The American Geophysical Union (AGU) is currently accepting abstract submissions for the 2018 Fall Meeting. The meeting will be held 10-14 December 2018 in Washington, D.C.

Conveners of the following sessions invite abstract submissions:

SESSION GC006: Advances in Understanding Causes and Consequences of High-latitude System Changes for Improved Sub-seasonal to Decadal Predictability
Conveners: Wieslaw Maslowski, Renu Joseph, Wilbert Weijer, and Hailong Wang

The polar regions have experienced some of the most dramatic changes currently occurring anywhere on Earth. Historical Earth System model (ESM) reconstructions are in broad agreement with these changes, however gaps remain in understanding and model representation of drivers of change in the polar systems and their impacts on lower latitudes. Reasons for that include sparseness of observations and challenges in understanding and representing critical processes and feedbacks in ESMs. The Interagency Arctic Research Policy Committee (IARPC) Arctic Science Plan is an example of an integrative approach for necessary coordination of regional observations and model improvements required to increase fidelity and predictive capability of future changes for decision making.

Conveners solicit presentations that advance understanding of the amplified response of high-latitude systems to environmental change, and its global impacts. Conveners are particularly interested in studies that synthesize modeling and observational approaches, while focusing on high-latitude processes and feedbacks, as well as polar¬–mid-latitude linkages.

SESSION EP020: From the Mountains to the Sea: Significance of Grain-Size Distributions in Stratigraphy, Sedimentology & Paleoclimatology - Analyses, Application, and Interpretation
Conveners: Bjoern Machalett, P. Thompson Davis, and Inka Meyer

Geological landscapes are shaped by processes that produce, transport and deposit mixtures of particles. Information on how sediment has been produced and modified is encoded in grain-size distributions, which evolve after sediment production by mixing from different sources, size reduction by physical and chemical attack, and sorting during transport and deposition. The detailed investigation of particle size distributions of sediments, suspended load, or aerosols is an increasingly used approach in assessing those environmentally driven geophysical processes in sedimentary systems. This session aims to provide a lively forum to review all aspects of particle size investigations applied to terrestrial, coastal, marine, lacustrine, or atmospheric environments, e.g. material sorting, land-atmosphere processes, sediment dispersal studies, advances in measurement techniques and data analysis, as well as statistical characterization and modeling of particle size distributions.
