The American Geophysical Union (AGU) is currently accepting abstract submissions for the 2017 Fall Meeting. The meeting will be held 11-15 December 2017 in New Orleans, Louisiana.

Conveners of the following three sessions invite abstract submissions:

  1. SESSION 23839: Past Climate Change in the Arctic and Subarctic: Lessons for the Future
    Conveners: Yarrow Axford, Meredith A. Kelly, and Erich C. Osterberg.

The Arctic's climate, cryosphere, and oceans are changing rapidly and influencing global climate systems. Understanding past warm conditions and past periods of climate change in the Arctic and subarctic will aid in forecasting future high-latitude changes and associated global impacts. Organizers invite submissions of proxy and modeling studies that assess the magnitude, rates, causes, and impacts of past climate changes in the Arctic and subarctic. Studies may address timescales from decades to millions of years. Organizers also welcome submissions that compare recent observations with paleoclimate records or that link past Arctic climate events to global changes.

  1. SESSION 22650: Ice Sheet and Glacier Change: integrating instrumental, geological and modelling methods to understand ice sheet and glacier evolution
    Conveners: Sarah Alice Woodroffe, Kristian K. Kjeldsen, Laura Levy, and Leanne Mary Wake.

Understanding the past evolution of ice sheets and glaciers, and producing predictions of future change requires a longer-term perspective than can be provided by geodetic data alone. The aim of this session is to improve our understanding of how and why glaciers and ice sheets change. The session focus is on investigating the multitude ways that glacier and ice sheet histories are reconstructed over a range of timescales from decadal to millennial.
Organizers welcome submissions that provide a new perspective by integrating instrumental, geological, and modelling techniques to understand past glacier or ice sheet change. In particular, organizers invite studies that focus on combining onshore and offshore records, different types of proxy data, a range of geodetic techniques, and/or innovative modeling approaches to enhance the understanding of past glacier or ice sheet evolution and help to better predict future changes.

  1. SESSION 22537: Geophysical Characterization of Coupled Cold Regions Hydrology and Permafrost Dynamics
    Conveners: Andy Parsekian, Martin A. Briggs, Burke J. Minsley, and Baptiste Dafflon.

The cold regions of Earth are changing, with significant impacts on landscape-scale hydrological processes. Surface and airborne geophysical methods are increasingly used to observe these changes because of the contrasts in geophysical properties that exist between frozen and thawed ground, or between solid-ice features and liquid water. In permafrost regions, geophysical methods also offer insight into groundwater flow, surface-water/groundwater exchange dynamics, and post-fire changes to the hydrologic system. This session is open to ground or airborne geophysical studies that focus on scientific objectives such as the detection and delineation of ground ice or permafrost, evaluating sub- and suprapermafrost water flow, thermokarst evolution, and monitoring active layer dynamics. Organizers will consider field-measured or modeled seismic, resistivity, ground-penetrating radar, gravity, magnetics, and other electromagnetic studies at any spatial scale. Organizers also encourage multidisciplinary projects that incorporate geophysics with the impacts of frozen material change on cold-regions ecology and/or biochemistry.
