The 27th IUGG General Assembly will be held from 8-18 July in Montréal, Québec, Canada.
The Palais des Congrès, Montréal
1. The PAGES 2k Network CLIVASH2k project encourages abstracts to the following IACS session:
C06 "New Frontiers in Paleoclimate Reconstructions and Proxy Interpretations from Ice Cores"
Convener: Barbara Stenni (Italy) Co-Conveners: Anais Orsi (France), Nancy A. N. Bertler (New Zealand), T.J. Fudge (USA)
This symposium welcomes contributions of state-of-the-art ice core science from both polar regions as well as mid and low latitude glaciers. We invite contributions on, but not limited to, the following topics: - results from new drilling campaigns - new analytical and drilling techniques -advances in ice-core proxy interpretations - paleoclimate reconstructions which may integrate other natural archives and / or develop array reconstructions - climate model simulations, including isotope enabled models - ice/bedrock investigations from ice core and fast access drilling projects.
We encourage contributions on different temporal scales spanning the past decades to glacial-interglacial cycles.
2. The PAGES working group C-SIDE encourages abstracts to the following sessions:
JP04 - Past changes, in the atmosphere, oceans and cryosphere, and their relevance for future climate (IAPSO, IAMAS, IACS, IAGA)
Convenors: K Kohfeld, A de Vernal, Q Yin, T von Dobeneck, M Patterson
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.
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 General circulation of the Southern Ocean turbulence and mixing; Air-sea interactions; Interactions with the cryosphere (sea ice, ice shelves); Biogeochemical processes; Recent and future changes in the state of the Southern Ocean; Advances in modeling and observing the Southern Ocean.
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 (Australia)
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.
The abstract submission has been extended to 1 March 2019.
