P01 - General Topics in Oceanography
Convener: Edmo Campos (Brazil)
Co-Conveners: Hosmay Lopez (USA), Elaine McDonagh (UK)
This symposium welcomes presentations of new results of research in physical and chemical oceanography concerning water masses and their interaction, currents, large-scale circulation and eddies, frontal zones and fronts, coastal upwellings and filaments, wind waves, internal waves, tides and other phenomena in different region of the ocean. Variability of oceanic processes on different space and time scale will be considered. The topics of the symposium also include chemical distribution and interactions, key problems in ocean colour, oil pollution, carbon cycle, acidification, and various extremes in the sea. The approach includes in situ and satellite observations, as well as numerical and laboratory modelling.
The symposium is intended to touch upon all problems of physical and chemical oceanography not included in the themes of other symposia.
P02 - Physics and Biogeochemistry of Semi-Enclosed, Shelf Seas, and Coastal Zones
Convener: Peter Zavialov (Russia)
Co-Conveners: Jianping Gan (China), Osmar Moller Jr (Brazil), Katrin Schroeder (Italy)
This interdisciplinary symposium provides a joint forum for oceanographers whose research focuses on physical, chemical, and biological processes in coastal zones, semi-enclosed and shelf seas of the World, as well as their responses to climate change and anthropogenic impacts. These areas are often characterized by complex interactions between land, ocean, and atmosphere, they exhibit rich dynamics driven by a variety of feedbacks and forcing mechanisms. Marginal seas and coastal areas are particularly vulnerable to climate change effects and anthropogenic stressors. Given their limited geographical extension and their sometimes constricted connection to the open ocean, these environments often exhibit shorter timescales in their responses to external forcing: this is why they are widely recognized as natural “laboratories” for studying oceanic processes and interactions between the physical, biogeochemical and climatic spheres. They also play an exceptionally important role in ecosystem services and socio-economic issues and require careful governance measures to avoid or mitigate environmental deterioration.
Gathering experts from different regions, the symposium will give a global perspective of the topic through comparison and elucidation of similarities and differences. Contributions on different regions are invited, related to themes such as innovative observational, theoretical, experimental and modeling studies of the hydrodynamics, marine biogeochemistry (e.g., nutrient dynamics, primary production, acidification, algae blooms) and the influence these regional seas and coastal zones exert on the adjacent basins/oceans and on the global scale. Studies of past, present and future climate variability are welcome, as well as interdisciplinary studies on the bio-physical interactions in semi-enclosed and shelf seas.
P03 - Storm Surges, Waves, and Coastal Hazards
Convener: Thomas Wahl (USA)
Co-Conveners: Ivan D. Haigh (UK), Marta Marcos (Spain), Aimée Slangen (Netherlands), Katherine Serafin (USA)
Invited speakers: Sanne Muis (The Netherlands), Dr. Philip Thompson (USA)
Extreme sea levels (excluding tsunamis) emerge as a combination of regional mean sea level, astronomic tides, storm surges caused by extra-tropical or tropical storms, a dynamic wave component leading to wave-setup and runup, and, in deltas and estuaries, river discharge. Resulting flooding events can have devastating impacts with wide ranging social, economic, and environmental consequences. The 2017 hurricane season in the North Atlantic was only the latest reminder of the vulnerability of low-lying densely populated and highly developed coastlines. In order to plan effective adaptation to coastal flooding hazards it is essential to improve the understanding of the superposition of the different extreme sea level components, and how they are modulated by climate change and variability, individually and in combination.
This symposium seeks contributions from studies that have: (i) examined changes in extreme sea levels and waves including the role of climate change and variability (past and future); (ii) undertaken statistical or process-based model analyses of extreme water levels or its individual components; (iii) assessed the various types of impacts (e.g., inundation, erosion, ecosystem degradation); (iv) or taken an integrated approach toward flood hazard and vulnerability evaluation of complex coastal systems as a result of extreme sea levels.
P04 - Mixing Processes in the Ocean
Convener: Toshi Hibiya (Japan)
Co-Conveners: Jody Klymak (Canada), Alberto Naveira Garabato (UK), Louis St. Laurent (USA)
The study of ocean mixing processes has made great strides through development of observation technology over the last decade such as the improvement of micro- and multi-scale profilers, innovation of ocean microstructure gliders and autonomous microstructure profilers. These new technologies enable field observations of ocean mixing processes to extend much deeper and wider than ever before. Needless to say, the accumulated knowledge of the observed features has stimulated theoretical and modeling studies related to ocean mixing processes such as internal wave-wave interactions, internal wave interactions with background shear, and associated energy cascade down to dissipation scales as well as assessment and reformulation of existing turbulent mixing parameterizations to be incorporated into the global circulation and climate models.
This symposium encompasses a wide variety of coastal and open ocean mixing processes; from the surface through the interior to the near boundary benthic mixing, including the roles of mixing in the biological processes and productivity of the ocean. Through detailed discussions, we would like to confirm how far our understanding of the ocean mixing processes has advanced over the last decade, defining the new frontier of ocean mixing research to be tackled in the next decade.
P05 - The Meridional Overturning Circulation: Mean State and Variability
Convener: Agatha de Boer (Sweden)
Co-Conveners: Christopher Meinen (USA), Arne Biastoch (Germany), Maria Paz Chidichimo (Argentina)
Invited Speakers: Susan Lozier (USA), Casimir de Lavergne (Australia), Laura Jackson (UK), Renellys C. Perez (USA)
The meridional overturning circulation (MOC) impacts society though its effect on sea level, surface air temperature, precipitation patterns, hurricane intensities and other climatically relevant quantities. MOC variations can occur on time scales ranging from days to centuries. Recognition of the importance of the MOC has resulted in intensive observational and modeling research over the past few decades and these studies have led to an ever-improving picture of how the MOC system works. Insights have come from all latitudes, from the deep water formation regions in the Greenland-Norwegian and Antarctic Seas to the subtropical North and South Atlantic basins, and everywhere in between. Major advances have depended upon theoretical and numerical modeling studies as well as on in situ observations, and taken together these breakthroughs are bringing into better focus the role that the MOC is playing in the global climate and carbon systems.
This symposium welcomes abstracts on observations, theory, and numerical modeling of the MOC on all timescales from the mean state, to daily, interannual, decadal, centennial and beyond.
P06 - Oceanic Boundary Current Systems
Convener: Hyodae Seo (USA)
Co-Conveners: Lisa Beal (USA), Moninya Roughan (Australia), Shoshiro Minobe (Japan)
Oceanic boundary currents play a crucial role in regulating the global climate system. Western boundary currents, such as the Gulf Stream, Kuroshio, East Australian, and Agulhas Currents, export excess heat, salt, and biota poleward via vigorous fronts and mesoscale eddies, and their extensions are known as hot spots of air-sea interaction and ocean warming. Eastern boundary currents, such as the California, Humboldt and Benguela Current Systems, feature coastal upwelling and energetic (sub)mesoscale variability, which support enhanced oceanic productivity. In the Atlantic Ocean, the deep western boundary current, forming a lower branch of the Atlantic Meridional Overturning Circulation, is an essential element of the global conveyor belt and of multi-decadal global climate variability. The Somali Current is seasonally-reversing and cross-equatorial, cooling mid-summer sea surface temperatures and affecting the Indian Monsoons. Studies have shown that these and other boundary current systems are undergoing rapid changes in a changing climate, suggesting they are critical regions of oceanographic and climate research.
This symposium seeks contributions on all aspects of oceanic boundary current systems based on observational, theoretical, and modeling studies. We welcome contributions involving analysis of novel techniques for measurements, theoretical investigations of the boundary current dynamics and diagnostic studies based on ocean/air-sea coupled models. Submissions of abstracts are particularly encouraged on the role of boundary currents in interior ocean dynamics, ecosystem, atmospheric storm tracks/jet stream, and climate variability, as well as on the interaction/connectivity of the boundary currents with coastal oceans and marginal seas.
Invited speakers: Magdalena Andres (USA), Joyce Ong (USA), Bernadette Sloyan (Australia), Ping Chang (USA)
P07 - The Southern Ocean: Where Ocean, Ice and Atmosphere Meet
Convener: Hajoon Song (Korea)
Co-Conveners: Isabelle Ansorge (South Africa), Andrew Stewart (USA)
The Southern Ocean connects all three major ocean basins and is a critical link in the interplay between atmospheric, biospheric, cryospheric and oceanic processes. Compared to other ocean basins, changes in the Southern Ocean exert a disproportionate influence over the global climate system, and addressing their causes and influences requires a comprehensive approach across the various disciplines.
This symposium aims to highlight recent advances in our understanding of Southern Ocean processes across all disciplines, including, but not limited to:
P08 - Coastal Ocean Acidification
Convener: Jessica N. Cross (USA)
Co-Conveners: Kumiko Azetsu-Scott (Canada), Debby Ianson (Canada), Carolina Cantoni (Italy), Michiyo Yamamoto-Kawai (Japan)
Ocean acidification (OA) is causing complex biogeochemical changes over a range of temporal and spatial scales. It can be extremely difficult to understand OA in the highly complex coastal zone. However, this rapidly emerging scientific issue has raised serious concerns across the scientific and resource management communities as to its possible impacts on highly productive coastal fisheries and food webs.
This symposium will highlight new research in coastal acidification, including changes in biogeochemistry; complexities associated with other ocean processes (e.g., freshwater mixing; hypoxia; multiple stressors); impacts on ecosystems and economies; and modeling and projection of future OA.
P09 - Marine Biogeochemistry Through Time: Nutrient, Trace Metal, Oxygen, and Carbon Cycling in the Past, Present and Future
Convener: Kate Hendry (UK)
Co-Conveners: Zanna Chase (Australia), Katja Fennel (Canada), Patrick Rafter (USA)
Ocean biogeochemistry is undergoing significant changes, with likely effects on primary production and ecosystem health from massive human perturbations of the global carbon and nitrogen cycles. Future projections are highly uncertain, but unlocking drivers and effects of biogeochemical reorganizations in Earth’s past may hold clues.
The aim of this symposium is to explore recent developments in our understanding of marine biogeochemistry at the interface of different disciplines. Topics could include limitation of primary production by micro-nutrients and macro-nutrients; the role of ecological interactions at the scales of populations, assemblages and ecosystems; boundary processes including sedimentary cycling, inputs from rivers, groundwater, the cryosphere and atmosphere; and physical movement that influences nutrient distribution and light availability by turbulent mixing, mesoscale eddies and large-scale ocean circulation. We welcome contributions that offer a broad perspective from a wide range of disciplines, including studies that utilise and bring together paleoclimate archives, modern oceanographic observations, and models.
P10 - Role of Ocean Processes in the Transport and Fate of Floating Plastic Litter in the Ocean and Shelf-Seas: Theory, Modelling and Observations
Convener: Erik van Sebille (Netherlands)
Co-Conveners: Kara Lavender Law (USA), Stefano Aliani (Italy), Nikolai Maximenko (USA)
After plastic debris enters the ocean, its distribution is to a large extent determined by the ocean circulation; in particular waves and currents. Knowing how and where marine debris is transported by the ocean is key to understanding its fate and impact on marine ecosystems.
Oceanographic phenomena that impact the transport and dispersion of buoyant marine debris occur on a large range of scales, from Stokes drift to Ekman convergence. The way that these different phenomena affect the dispersion of marine debris, and how this leads to the emergence of patchy accumulation regions and ‘hotspots’, is a major knowledge gap.
In this symposium, we invite presentations on advances in the theory and modelling, possibly supported by observations, of marine plastic debris of all sizes. Topics include but are not limited to:
P11 - Transitioning Towards an Inclusive Blue Economy: What Does It Take?
Convener: Essam Yassin Mohammed (UK)
Co-Conveners: Denise Smythe-Wright (UK)
Marine and coastal resources provide millions of impoverished people across the world with livelihoods, and provide a range of critical ‘ecosystem services’, from biodiversity and culture to carbon storage and flood protection, recreation and amenity opportunities. One billion people in the world rely on fish as their main or only source of animal protein, and more than 300 million are directly or indirectly employed by the fisheries sector. But global fish stocks are under threat from overfishing, pollution, habitat destruction and climate change. Despite their importance to large numbers of people around the world, fisheries have been ignored by mainstream policymakers for too many years because of misallocation of incentives and investments, compounded by ill-defined property rights, in which short-term profits come at the expense of long-term viability. The consequences of continued inaction could now be catastrophic. Unless threats to marine and coastal ecosystems are reversed, millions of livelihoods could be lost and numerous communities will have reduced access to a staple food that they rely on for their survival. Blue economy is an emerging approach to balance the three dimensions of sustainability in the ocean space. Contributions are invited to discuss the following key questions:
P12 - Technological Advances for Ocean Sciences
Convener: Hans van Haren (Netherlands)
Co-Conveners: Rajesh Nair (Italy), Sung Yong Kim (South Korea), Ken Johnson (USA)
The emerging paradigm for global marine observing activity envisages a “digital ocean” - a multitude of sensors measuring many variables, distributed across the seafloor, within the water column, at the sea surface, in the atmosphere and in space.
This symposium aims to bring to light recent or ongoing developments in the fields of marine instrumentation and observing infrastructure. The developments may range from innovations to state-of-the-art technologies to completely new designs, in various operating contexts: manual, standalone and networked. Contributions may cover purely technical and implemental or scientific aspects, or both.
JOINT SYMPOSIA WITH OTHER ASSOCIATIONS LED BY IAPSO
JP01 - Tides of the Oceans, Atmosphere, Solid Earth, Lakes and Planets (IAPSO, IAHS, IAMAS, IAG)
Convener: Philip Woodworth (UK, IAPSO)
Co-Conveners: Richard Ray (USA, IAPSO), Andreas Richter (Argentina, IAHS), Jean Paul Boy (France, IAG), Jeffrey Forbes (USA, IAMAS)
Invited speakers: Richard Ray (USA), Brian Arbic (USA), Steven Balbus (UK), Duncan Agnew (USA), Jens Oberheide (USA), Luciano Iess (Italy), Andreas Richter (Argentina)
The symposium will be open to any aspect of the science or history of the tides of the ocean, solid earth and atmosphere and of lakes and planets. The science will include the present accuracy of coastal, regional and global ocean tide models, tidal dissipation and its role in geophysics, internal tides and their role in mixing the ocean and in the global ocean circulation, secular changes in tides, new techniques for measuring tides and analysing the data, the role of tides in the origin of life on earth and palaeotides. It will also be open to presentations on earth and atmospheric tides, the tides of lakes and planets and many other aspects of tidal science. The symposium will provide a fitting mark of the 100th anniversary of the Liverpool Tidal Institute which led to many advances in tidal science in the 20th century.
JP02 - The North Atlantic-Arctic System: State, Process, and Change (IAPSO, IAMAS)
Convener: Thomas Haine (USA, IAPSO)
Co-Conveners: Paul Myers (Canada, IAPSO), Takashi Kikuchi (Japan, IAPSO), Rodrigo Caballero (Sweden, IAMAS), Mojib Latif (Germany, IAMAS)
The North Atlantic-Arctic Ocean, Atmosphere, and sea ice system influences regional, hemispheric, and global climate. It is where anthropogenic climate change is most conspicuous, such as the decline in summer-time sea ice, and very uncertain, like the future of the Greenland Ice Sheet. Recognition of these facts in the last decade, and greatly expanded observing networks, are revolutionizing knowledge and understanding of its physical oceanography, biogeochemistry, cryospheric, and atmospheric sciences. This symposium invites contributions quantifying the current state of the North Atlantic/Arctic system, elucidating processes that maintain that state, and investigating how it is changing. The symposium will bring together observers, modelers, and theorists to report latest research.
JP03 - Long-Term Climate Targets: from Emissions to Impacts (IAPSO, IAMAS, IACS, IAHS)
Conveners: Kirsten Zickfeld (Canada, IAPSO)
Co-Conveners: Eric Servat (France, IAHS), Ben Marzelon (Germany, IACS), Aimee Slangen (Netherlands, IACS), Nadine Mengis (Canada, IAMAS)
Long term global temperature and sea level increases are primarily determined by total anthropogenic emissions of carbon dioxide, though shorter-lived greenhouse gas emissions can also leave a long-term warming legacy. Limiting cumulative greenhouse gas emissions by decreasing net emissions to zero is therefore a prerequisite to stabilize long-term global temperatures and slow down sea level rise. Under the Paris Agreement, the world has committed to limiting long term warming to “well below 2°C” (and ideally to 1.5°C) above pre-industrial temperatures, in an attempt to avoid the most dangerous potential impacts of climate change. The scientific challenge is therefore to understand the climate warming legacy of current greenhouse gas emissions, to determine what levels of long term warming and sea level rise would produce unacceptably damaging impacts, and to better quantify the emissions budgets and pathways that would succeed in avoiding these levels of climate change. In this symposium, we welcome contributions on all aspects of this challenge.
Invited Speakers: Kiya Riverman (USA), Pietro Milillo (USA)
JP04 - Past Changes, in the Atmosphere, Oceans and Cryosphere, and their Relevance for Future Climate. (IAPSO, IAMAS, IACS, IAGA)
Convener: Karen Kohfeld (Canada, IAPSO)
Co-Conveners: Qiuzhen Yin (Belgium, IAMAS), Anne de Vernal (Canada, IAMAS), Tilo von Dobeneck (Germany, IAGA), Molly O. Petterson (USA, IACS)
Paleoceanographic and paleoclimatological research provides information on climate dynamics and biogeochemical cycling through time based on proxy reconstructions or model simulations of physical, chemical, and biological characteristics of the earth system. This symposium invites a wide range of data- and modeling-based presentations that aim to understand past behaviour of climate, ocean and ice. Submissions are encouraged on a range of topics, including glacial inceptions, millennial climate variability and abrupt change, characteristics of full glacial states, as well as past warm periods and their terminations as a means to better understand the future climate and its impacts on environment and ecosystems.
JP05 - Tsunamis (IAPSO, IASPEI, IAVCEI)
Convener: Vasily V. Titov (USA, IAPSO)
Co-Conveners: Fumuhiko Imumura (Japan, IAPSO), Maria Ana Baptista (Portugal, IAPSO), Alexander Rabinovich (Russia, IASPEI), Joan Marti (Spain, IAVCEI)
Tsunamis present persistent hazard for growing coastal population around the world. Tsunami events of this century vividly illustrated increasing risk of such disasters for coastal population and infrastructure. As the response to these deadly tsunamis of the XXI century, many new tsunamis forecast and warning capabilities have been developed and implemented. Tsunami warning systems have expanded from the Pacific to all world oceans, and now provide tsunami warning capabilities based on expanded set of real-time observations for virtually all vulnerable coastlines.
The global warning system presents new challenges for tsunami science. Newly available real-time data provide large volume of high-quality observations that require new methods and data-assimilation tools for use in data-based forecast products. New modelling and analysis methods are required to take advantage of the new computational and observational capabilities, to convert scientific and modelling results into actionable and effective forecast and warning. The tsunami science now has the opportunity to make all coastal communities resilient to tsunami threat. The symposium will discuss progress and challenges of all aspects of tsunami research and practical warning applications.
JP06 - Risk and Maritime Extremes (IAPSO, IAMAS)
Convener: Will Perrie (Canada, IAPSO)
Co-Conveners: Mark Hemer (Australia, IAPSO), Jeniffer Brown (UK, IAPSO), Xiaolan Wang (Canada, IAMAS), David Atkinson (Canada, IAMAS)
Climate change is increasingly impacting on human activities and communities. For example, as a consequence of sea level rise, coastal flooding events occur more often. Over land, heat waves seem to be experienced with increasing frequency. It is essential that society develops the capability to estimate the frequency, magnitude and impact of these extreme events, in order to adapt to and prepare for their changing tendencies and thus to try to mitigate their future impacts.
The objective of this symposium is to stimulate discussion and exchange ideas related to statistical methodologies across the various relevant areas of environmental science, with a focus on maritime studies. Statistical modelling of complex extreme events has developed rapidly in recent years; theoretical analysis has transitioned to multivariate statistical tools with many environmental applications. We hope to examine the state-of-the-art in present approaches and methodologies, identify challenges and opportunities, and motivate new research interactions and developments.
Presentations from all areas of marine environmental science are welcome with a particular emphasis on the combinations of factors that can in some cases be related; our aim is to showcase mesoscale extreme events and to learn from other disciplines to improve maritime risk assessment. Coastal flooding can result from nonlinear interactions of multiple oceanographic, hydrological, geological, and meteorological processes (e.g. tides, sea-level anomalies, storm surge, waves, winds, fluvial discharges, precipitation, beach, loss and land subsidence). Moreover, although exceptional extreme variations of a single process (e.g. storm surge), can result in coastal flooding, the more normal situation is that a combination of notably high values of more than one process constitute the precursor mechanism, thereby making a compound extreme event. Additional topics can consider extremes related to lake-effect (or lake-modified) systems and coastal extreme weather. In many cases, processes are often not stationary, but vary with season, and on time-scales of years, decades, etc., with changing climate. Thus, characteristics of extreme events can may be described as: the extreme nature of the impact rather than individual component factors, the multivariate nature of the impact, and the statistical dependence of component factors.
OTHER IAPSO JOINT SYMPOSIA WITH OTHER ASSOCIATIONS LEADING
JA02 - Geophysical Data Assimilation (IAGA, IACS, IAG, IAHS, IAMAS, IAPSO, IASPEI, IAVCEI)
Convener: Sabrina Sanchez (Germany, IAGA)
Co-Conveners: Marie Bocher (Switzerland, IASPEI), Matthias Morzfeld (USA, IAGA/IAMAS), Takemasa Miyoshi (Japan, IAMAS), Entcho Demirov (Canada, IAPSO), Julien Brajard (France, IAPSO/IACS), Salvatore Grimaldi (Italy, IAHS), Pavel Novak (Czech Republic, IAG)
Data assimilation has become a valuable tool for improving our understanding of the Earth and its different dynamical layers, such as the core, mantle, oceans, atmosphere and magnetosphere. By merging sparse observations, complex physical models and their respective errors, data assimilation attempts to unveil hidden features of a given system as well as predicting its evolution. Although its long-term development in the field of meteorology has led to a well-established framework, data assimilation methodologies still bear considerable challenges. Amongst those we can cite the numerical stability of ensemble-based methods such as the Ensemble Kalman Filter, the identification and handling of model errors and biases, the hybridization of variational and sequential approaches, and the usage of multi-model ensembles for parameter estimation. Moreover, in many fields of application, such as core and mantle dynamics, as well as volcanism and space weather, data assimilation remains fairly exploratory. However, these novel applications can provide a platform for further analysis of the aforementioned challenges. This symposium aims at promoting a constructive dialogue between the different geophysical communities with a shared interest in the development of innovative strategies in data assimilation. We therefore particularly encourage the participation of contributions connected to emerging research fields of geophysical data assimilation, as well as the development of libraries, testbeds and computationally efficient data assimilation schemes.
JA07 - Geoscience Data Licensing, Production, Publication, and Citation (IAGA, IACS, IAG, IAHS, IAMAS, IAPSO, IASPEI, IAVCEI)
Convener: Masahito Nosé (Japan, IAGA)
Co-Conveners: Simon Flower (UK, IAGA), Yasuhiro Murayama (Japan, IAMAS), Helle Pedersen (France, IASPEI), Attilio Castellarin (Italy, IAHS), Gabriel Guimarães (Brazil, IAG), Toru Suzuki (Japan, IAPSO), Aude Chambodut (France, UCDI), Giuseppe Puglisi (Italy, IAVCEI)
A number of national and international geoscience research infrastructures have been created in recent years, for example, EPOS (the European Plate Observing System), Copernicus (European Union's Earth Observation Programme), IUGONET (the Inter-university upper atmosphere global observation network), EarthCube (the ‘system of systems’ infrastructure for geosciences) and AuScope (the Autralian geoscience and geospatial infrastructure). At the same time the World Data System is evolving and certification of data repositories (ICSU-WDS, CoreTrustSeal) is becoming an important concern. Together these initiatives make it possible for users to easily access huge archives of disparate geoscience data and metadata in a secure and reliable manner, a task that was complex and time consuming before these initiatives were available.
Clear licensing of geoscience data gives users clarity over how they can use and share the data, protects the rights of data providers and promotes integrated research. Data publication and citation will benefit data suppliers by giving them proper credit, professional recognition and rewards for their works, in a similar manner to the way that publication of scientific results benefits scientific researchers. Licensing, publication and citation of data are becoming a requirement for contribution to geoscience infrastructures. The system of licensing, producing, publishing, and citing of geoscience data is a structure for persistent intellectual content identification and management as well as for connection of users with content suppliers.
This symposium solicits contributions presenting actual practices and future plans of data licensing, producing, publication, and citation of scientific data, and possible related topics.
JA12 - Innovation in Geoscience Education, Outreach and Citizen Science (IAGA, IAHS, IAPSO, IASPEI)
Convener: Manoj Nair (USA, IAGA)
Co-Conveners: Rick Saltus (USA, IAGA), Edgar Bering (USA, IAGA), Barbara Leichter (Austria, IAGA), Christophe Cudennec (France, IAHS), Isabelle Ansorge (South Africa, IAPSO), Laura Gallardo (Chile, IAMAS), Raju Sarkar (Bhutan, IASPEI), Paul Denton (UK, IASPEI), John Taber (USA, IASPEI),
This Symposium calls for papers describing innovations in geoscience instruction methods and citizen science initiatives. Papers are welcome describing advances in all levels of instruction, including secondary and higher education. We are particularly interested in papers about inventive approaches to inquiry-based learning in all geosciences. Involving students and the public in designing experiments and collecting data has been shown to foster a scientific identity, to increase overall interest in science, and to improve the perceived value of scientific research. Papers are welcome on all aspects of education and citizen-science including methodology, data-collection, non-traditional areas of curriculum, case studies, etc. In particular we invite contributions that describe ways to broaden the public understanding and appreciation of science and to attract non-traditional and under-represented students into the sciences.
JC01 – Projecting Sea Level in the 21st Century and Beyond (IACS, IAMAS, IAPSO)
Convener: Andy Aschwanden (USA, IACS)
Co-Conveners: Ben Marzeion (Germany, IAMAS), Gary T. Mitchum (USA, IAPSO)
The seas are currently rising, and the rise is expected to continue into the 21 century and beyond, challenging societies around the globe. The primary contemporary contributors to global mean sea level are thermal expansion due to warming oceans and melting glaciers and ice sheets. Spatially-varying changes in absolute and relative sea level arise from the associated changes in solid Earth loading and variability of the Earth's gravity field. This joint symposium brings together the fields of glaciology, oceanography, atmospheric sciences, hydrology, and solid earth geophysics to assess the relative importance of each component and their respective uncertainties over the next centuries with focus on both regional and global sea level changes.
JC02 – Atmosphere-Ocean-Sea Ice Interactions: Local Processes and Global Implications (IACS, IAMAS, IAPSO)
Convener: John Cassano (USA, IAMAS)
Co-Conveners: Hiroyuki Enomoto (Japan, IACS), Elisa Manzini (Germany, IAMAS), Matthew Lazzara (USA, IAMAS), James Renwick (New Zealand, IAMAS), Thomas Spengler (Norway, IAMAS), William Perrie (Canada, IAPSO)
Changes in the Arctic and Antarctic climate system are strongly related to atmosphere-ocean-ice (AOI) interactions. Phenomena such as the dramatic decrease in sea ice extent in the Arctic over the past 30 years contribute to rapid regional warming through feedbacks between the atmosphere, ocean, and sea ice. On the other hand, Antarctic sea ice variability is internally dominated with no strong multi-decadal trend. Understanding and modelling these variations in the coupled AOI system remains a challenge at both poles. AOI interactions are also associated with synoptic weather systems and mesoscale extreme weather phenomena such as cold air outbreaks, katabatic winds, and polar lows. In the Arctic, for example, sea ice loss is associated with rapid regional warming which is often tightly linked to mid-latitude weather and climate. Arctic sea ice loss may also impact the state of the stratospheric vortex, which in turn can affect the large-scale hemispheric circulation in the troposphere. Furthermore, in the Antarctic, sea ice change may affect ice shelf behaviour and hence could affect sea level change. The representation of these physical processes and interactions at different spatial and temporal scales, however, remains a major challenge for current weather and climate models.
This symposium brings together researchers working in the areas of polar meteorology and oceanography as well as sea ice to focus on physical processes as well as on global change related to the Arctic and Antarctic. Special emphasis is on the coupling between the ocean, ice, and atmosphere and the interactions between the Polar Regions and the large-scale hemispheric and global circulation. Further focus is on processes and parameterizations related to physical exchange, including the influence of sea ice floe-size distribution and sub-mesoscale ocean/sea ice dynamics and thermodynamics. Contributions are welcome dealing with theoretical and observational studies, including remote sensing, as well as studies using numerical models.
JC07 – Gravity-Driven Flows in the Earth System (IACS, IAPSO, IAVCEI)
Convener: Jim N. McElwaine (UK, IACS)
Co-Conveners: Dieter Issler (Norway, IACS), Federico Falcini (Italy, IAPSO), Roberto Sulpizio (Italy, IAVCEI)
Gravity-driven flows ― subaqueous and subaerial, terrestrial and extra-terrestrial ― occur in a variety of types that nevertheless share many features. There is large potential for improving our understanding of these fascinating and practically important phenomena by comparing experimental data and mathematical modelling approaches across traditional subdiscipline boundaries.
This interdisciplinary symposium therefore aims to summarize our current understanding of, and identify future research challenges in, gravity-driven flows.
Contributions are welcomed on the following topics, among others:
JG04 - Geodesy for Atmospheric and Hydrospheric Climate Research (IAG, IAMAS, IACS, IAPSO)
Convener: Annette Eicker (Germany, IAG)
Co-Conveners: Rosa Paccione (Italy, IAG), Sonia Seneviratne (Switzerland, IAMAS), Stephen Price (USA, IACS), Benoit Meyssignac (France, IAPSO)
Invited Speakers: Anny Cazenave (France), Natalya Gomez (Canada), Gottfried Kirchengast (Austria)
The growing record of (space-)gravimetric and geodetic data (GRACE, GNSS, radar altimetry, InSAR, VLBI, tide gauges…) provides a new view on Essential Climate Variables such as tropospheric water vapor, water storage and ice mass changes, steric and barystatic sea level, sea surface winds, waves, sea ice extent/thickness, or the Earth’s energy imbalance. These observations have the advantage to be globally homogeneous, and independent from other data commonly used to develop and evaluate climate models.
Geodetic time series reveal a complex picture of natural climate variability, long-term climate change and anthropogenic modifications. Combined with other observations or re-analyses, they provide excellent tools to assess climate models and improve our understanding of land- and ocean-atmosphere interactions.
We invite contributions dealing with (1) using geodetic data to characterize, analyse, and understand current climate change, (2) evaluating climate models against geodetic data, (3) using these data to constrain and improve climate projections, (4) creating long and consistent geodetic time series, (5) climate modelling of geodetically observable variables, and (6) the prospects of future missions.
JG06 - Monitoring Sea Level Changes by Satellite and In-Situ Measurements (IAG, IAPSO)
Convener: Xiaoli Deng (Australia, IAG)
Co-Conveners: Fabio Raicich (Italy, IAPSO)
As the climate continues to warm, it is important to precisely measure sea level changes and its different components at both global and regional scales. This IAG-led Joint Symposium JG6 symposium invites contributions from studies that monitor and observe sea level changes on multiple scales employing satellite altimetry, GNSS at tide gauges, GNSS reflectometry, airborne laser scanning, satellite gravimetry and in-situ measurements.
Topics to be covered, but not limited to, include (1) precise mapping and monitoring of the sea level variability on different time and spatial scales; (2) relationship between the sea levels from satellite altimeters (since 1993) and terrestrial water storage estimates from GRACE satellites (since 2002); (3) separation of inter-annual and decadal-scale sea level variability from now 25-year altimeter records for a robust estimate of the long-term sea level trends; (4) climate contributions to sea level rise, and (5) the estimation of the sea level budget.
JM05 - Ocean-atmosphere Mechanisms of Variability, Change and Predictability (IAMAS, IAPSO)
Convener: Tim Woolings (UK, IAMAS)
Co-Conveners: Hisashi Nakamura (Japan, IAMAS), Iracema Cavalcanti (Brazil, IAMAS), Toshio Yamagata (Japan, IAPSO)
This symposium welcomes contributions of theoretical, modelling and observational work related to ocean-atmosphere variability and change. Interaction between the ocean and atmosphere plays an important role in many aspects of climate variability, predominantly from seasonal timescales upwards. The associated teleconnections cover the globe and can also interact with other systems such as the land and cryosphere. The long timescales inherent in such coupled variability proves an invaluable source of skill for near-term climate predictions in particular, but the longer term forced climate change signal is also significantly affected by ocean-atmosphere coupling.
Specific topics covered by the symposium include but are not limited to: Tropical coupled variability and teleconnections; mechanisms of mid-latitude air-sea interaction; the role of ocean frontal zones and eddies in the coupled system; representation of air-sea interaction and teleconnections in climate models; role of ocean variability in near-term climate predictability; and ocean-atmosphere coupling under anthropogenic climate change.
JM08 - Earth System Models: Assessing the Earth System’s State and Fate from Regional to Planetary Scales (IAMAS , IAPSO, IACS, IAHS)
Convener: Paul Kushner (Canada, IAMAS)
Co-Conveners: Nathan Gillet (Canada, IAMAS), Marika Holland (USA, IAPSO), Gerhard Krinner (France, IACS), Sophie Nowicki (USA, IACS), Manuela Girotto (USA, IAHS), Stephen Déry (Canada, IAHS)
Earth System Models provide our principal means to simulate Earth System processes and to predict the evolution of the planet. Each generation of Earth System Models, including components that simulate the atmosphere, oceans, land, vegetation, ice, snow, and the dynamical and biogeochemical processes that link these components, has provided new insights into the workings of the Earth System, predictions from seasonal to decadal scales, and projections of the future of the planet under greenhouse warming and other sources of radiative and compositional driving. These models have progressively simulated finer scales, and through regional refinement or downscaling can be used to investigate regional-scale climate processes and impacts. This symposium encourages contributions dealing with the many facets of Earth System Model development and application, including new modelling results from the Coupled Model Intercomparison Project Phase 6, development and assessment of models making use of recent Earth observations from ground-based and space-based measurements, prediction of climate on seasonal to centennial timescales, climate change detection and attribution, regional-scale climate modelling and process analysis, high resolution climate modelling, and subgrid scale parameterization development. As a joint symposium, submissions on the latest advances in Earth System Modeling across the atmospheric, biogeochemical, oceanic, cryospheric, and hydrological sciences are encouraged.
JM09 - Satellite Remote Sensing: Vital Information on the Health of our Planet (IAMAS, IACS, IAPSO, IAHS)
Convener: Kaley Walker (Canada, IAMAS)
Co-Conveners: Bojan Bojkov (Germany, IAMAS), Yangbo Chen (China, IAHS), Yasko Kasai (Japan, IAMAS), Paul Kushner (Canada, IACS), Stephen Howell (Canada, IACS), Stefano Vignudelli (Italy, IAPSO), Nicolas Grisouard (Canada, IAPSO), Yanping Li (Canada, IAHS), Hong Lin (Canada, IAMAS)
Space-based observations provide a unique global perspective on the Earth's atmosphere and surface, including the oceans, land, vegetation, ice, and snow. Current and planned satellite missions from Canada, and international agencies in US, Europe, China and Japan have provided and will provide a wealth of new information about the Earth system and that can be used to investigate a wide range of environmental and scientific questions. This symposium encourages contributions dealing with the many facets of space-based remote sensing, including new measurement technologies and techniques, both passive and active; retrieval algorithms; validation of satellite products; assimilation of data into numerical models; scientific results and discoveries and operational utilization and development.
JS06 - Old Data for New Knowledge: Preservation and Utilization of Historical Data in the Geosciences (IASPEI, IAG, IAHS, IAGA, IAMAS, IACS, IAPSO, IAVCEI)
Convener: Josep Batlló Ortiz (Spain, IASPEI)
Co-Conveners: Alberto Viglione (Austria, IAHS), József Ádám (Hungary, IAG), Edward Cliver (USA, IAGA), Kris Harper (USA, IAMAS), Bruce Raup (USA, IACS), Florence Fetterer (USA, IACS), E. Pattabhi Rama Rao (India, IAPSO), Roberto Carniel (Italy, IAVCEI)
Studying a changing world needs long series of data. Moreover, reanalysis of old geophysical/geodetic data in the light of our present knowledge has become an important tool for understanding topics such as solar variability, climatic change, tectonics, earth rotation, and extreme natural events (e.g., magnetic storms, hurricanes, rainfall, floods, earthquakes etc.). Those old data are in analogue form and, many times, are contained in unique documents. Historical information may also be retrieved from documentary evidence such as narrative sources and legal-administrative institutional documentation (e.g. chronicles, newspapers, private and official protocols and correspondence, account books, etc.). Techniques and methodologies for preservation, dissemination, interpretation, homogenisation and use of such data, as well as for their present scientific use are important topics for advancing of our understanding of the changing Earth and of past extreme events. Different approaches have been devised to deal with different data and problems. Sharing the already large accumulated experience in the different fields covered by the IUGG shall contribute to improve our preservation and dissemination tools, our analysis methods and, ultimately, to further research results. This symposium welcomes contributions on:
(a) Locating, assessing, preserving, and disseminating historical data about sunspots, polar motion, time and temperature measurements, magnetograms, seismograms, eruptions, glacier extent, tide gauge records, aurorae, flood/drought events and many others and
(b) Methodologies and study cases using these historical data to advance our understanding of the Earth.
JV05 - Recent Advances in Subaqueous Volcanism Derived from Ancient and Modern Volcanic Successions, Laboratory and Numerical Approaches (IAVCEI, IAPSO)
Convener: James White (New Zealand, IAVCEI)
Co-Conveners: Karin Orth (Australia, IAVCEI), Adam Soule (USA, IAVCEI), Evi Nomikou (Greece, IAVCEI), Steffen Kutterolf (Germany, IAVCEI), Rebecca Carey (Australia, IAVCEI), Chris German (USA, IAPSO)
Seventy percent of Earth’s volcanoes are hidden beneath the surface of the oceans. Although largely ‘invisible’, submarine volcanoes are responsible for >75% of Earth’s magma output, and the eruptions put gas, heat, and volcanic material into the hydrosphere and atmosphere as well as greatly influence biogeochemical processes.
This symposium will include presentations of both terrestrial ancient marine volcanic environments modern-day submarine volcanic systems, with the aim of enabling cross-fertilization of ideas. We call for abstracts for field, laboratory and numerical studies of submarine volcanism. We also call for abstracts that combine innovative and emerging technologies that enable breakthrough developments for advancement of knowledge in submarine volcanism.
