The American Geophysical Union (AGU) is currently accepting abstract
submissions for the 2013 Fall Meeting. The meeting will be held 9-13
December 2013 in San Francisco, California. Conveners of the following
sessions invite presentations from the Arctic community:

C023 - Polar Technology Enabling Science
New and rapidly evolving technologies, including communications, low
power electronics and sensors, energy source and storage systems,
advanced signal processing, and cyberinfrastructure, are enabling new
capabilities and enhanced science at high latitudes. This session is
intended for posters that document available technology enabling science
at fixed locations and on mobile land, sea, and air platforms in Polar
Regions that have been deployed or are under development.

C022 - Polar Snow and Firn: Physical and Chemical Processes in the Snowpack
Advanced technology has improved capabilities to monitor and model snow
and firn changes relating to atmospheric processes. The snowpack is
important in the Earth system, with increasing significance to
tropospheric chemistry. Interactions between the atmosphere and surface
influence accumulation, metamorphism, densification, and chemistry and
alter microstructure and stratigraphy. This session focuses on field,
laboratory, and modeling work on polar snow and firn processes. We
invite abstracts on these processes, including those which influence
chemistry, photochemistry, metamorphism, and physical and radiative
properties. Papers applying new technologies and incorporating these
data into modeling efforts are welcomed.

PP002 - Aeolian Dust in Earth's Climate System
Rapid advances in the application of highly resolved sedimentological
and geochemical studies, in combination with geochronometric techniques
and chronostratigraphic tools, have opened up new vistas in the
investigation of (paleo)records of atmospheric dust loading using
aeolian sediments. As these sediments are widespread on the continents,
novel multi-proxy investigations enhance our understanding of long-term
aeolian dust dynamics and climate variability. Innovative contributions
are welcome on the application of new and established methodological
approaches; including stratigraphy, geochronology, paleoclimatology,
paleoenvironmental assessment, dust in climate models, and
geoarchaeology of aeolian deposits in the Northern and Southern
Hemispheres.

C011 - Glacier, Ice Cap, and Ice Sheet Hydrology
The hydrologic system of glaciers, ice caps and ice sheets and their
downstream rivers is intrinsically linked to their responses to climate
variability. This system may take a variety of forms, and include firn
layers, supra- and sub- glacial lakes, streams, transport pathways
through moulins, crevasses, and other conduits. We invite contributions
examining this development and function of the coupled hydrological
system, its significance and importance, storage and retention
components and interactions between this system and ice thermal state,
dynamics, and water and energy exchange. This includes movement of water
between sub-glacial lakes, supra-glacial lake storage, rivers and
interactions with seawater in marine environments.

C013 - Hydrological Response to Climate Change in Permafrost Regions
Permafrost degradation has led to phenomena such as thickening of the
active layer, increased release of C and N into ecosystems, increasing
contribution of groundwater discharge to winter baseflow in rivers and
thermokarst driven wetting or drying of landscapes. Hydrological
response is highly diverse depending on climate, permafrost continuity
and other landscape attributes including hydrogeology, topography,
geomorphology, vegetation and disturbance regime. This session aims to
develop a framework to characterize the current state of permafrost
hydrology, and investigate the similarities and differences in behavior
across diverse permafrost landscapes in order to project climate driven
hydrological response in the future.

OS020 - Sustainable Oceans
The session will highlight the interconnected issues arising from human
impact on our oceans. It will focus on the role of the Earth sciences in
translating basic knowledge into designs for solutions to existing and
emerging problems. The Arctic is the region that shows many effects of
human development of our planet at amplified amplitudes. The session
provides an ideal platform for highlighting issues of sustainable
development of the Arctic in a changing global environment.

H012 - Changes in the Arctic Freshwater System
Climate change and variability are affecting freshwater systems within
the Arctic domain, thereby also modifying both marine and terrestrial
biogeophysical processes. This session focuses on how major Arctic
freshwater source, flux and storage components are being modified,
including: atmospheric and river transport,
precipitation-evaporation-permafrost/soil moisture regimes, glacier/ice
cap mass balances, sea-ice formation/ablation, and marine exchanges
including oceanic storage/release of low-salinity water. Also of
interest are ecological and socio-economic effects that cascade from
changes in these freshwater components and related processes.

H077 - Role of Remote Sensing in Ecohydrology and Biogeophysics
Remote sensing and sensor networks are important tools for studying
interactions among boundary-layer atmosphere, climate, soil, and
vegetation. Hydrological processes impact the ecology through changing
biogeophysical variables such as biomass, leaf area index, water content
in vegetation, leaf structural index, etc. This session solicits
presentations with interdisciplinary foci especially in the nexus of
ecohydrology and biogeophysics with the aid of remote sensing
techniques, including visible near infrared, thermal infrared, active or
passive microwave, gravity and magnetic, electromagnetic methods, etc.
or any combination of these techniques at scales from a single leaf to a
continental region.

The abstract submission deadline for all sessions is Tuesday, 6 August
2013 at 11:59 p.m. Eastern Daylight Time. The first author must be a
current 2013 AGU member. Details on abstract submission are available at:
