The American Geophysical Union (AGU) is currently accepting abstract
submissions for the 2014 Fall Meeting. The meeting will be held 15-19
December 2014 in San Francisco, California.
IMPORTANT NOTE: The abstract submission tool is new this year. AGU
organizers strongly recommend review of the tutorial on the abstract
submission process prior to submission.
Conveners of the following eight sessions invite presentations from the
Arctic community:
Session 3400: Arctic hydrology in a changing climate
Conveners: Cathy Wilson, Stan Wullschleger, and Larry Hinzman.
Session description: How does permafrost hydrology vary across landscape
gradients in the Arctic, and what factors control its evolution with
climate warming? Conveners invite presentations that examine the roles
of climate, topography, sub-surface properties, geomorphic setting,
ecology and permafrost conditions on hydrologic system behavior from
local to regional scales. Modeling, data synthesis and observational
studies that highlight either current hydrologic processes or future
trends are welcome. Presentations on research related to discontinuous
and shallow permafrost regions are particularly welcome.

Session 3716: Coast and Nearshore Mapping Efforts in Alaska
Conveners: Thomas Heinrichs and Ann Gibbs.
Session description: Many Alaskan coastal communities and habitats are
increasingly threatened by coastal erosion, storm-surge flooding, and
potential oil spills, all of which are likely to intensify in the future
as sea-ice melts and temperatures warm. Accurate maps of the coast,
including both bathymetry and topography, are fundamental for assessing
historical changes as well as modeling and projecting future impacts to
the coast. Historically the Alaskan coast and nearshore regions have
been poorly mapped. Elevation data are coarse and existing geodetic and
offshore water-level information is insufficient. This session invites
contributions from new coastal and nearshore mapping efforts in Alaska
focusing on new technologies, overcoming existing technical challenges,
and/or demonstrating how coastal mapping efforts relate to climate
change, coastal hazards, ecosystem management, and oil spill response.
Oral and poster contributions are welcome.

Session 2980: Natural Wetlands and Open Waters in the Global
Methane Cycle
Conveners: Elaine Matthews, Martin Wik, Torsten Sachs, and Ruth Varner.
Session description: Natural wetlands and open waters (lakes, ponds,
streams, reservoirs) are major, climate-sensitive methane (CH4) sources.
Uncertainties in CH4 dynamics from these landscapes derive from
heterogeneity in vegetation, microtopography, permafrost, hydrology, and
CH4 production and emission. Sign and magnitude of responses of wetland
and open-water distributions and their emissions under warming climate
are uncertain. Understanding and modeling distributions and CH4 dynamics
of these heterogenous ecosystems is crucial to predicting biogeochemical
and distributional dynamics under past, present and future climates.
Studies on: global-to-regional modeling of CH4 dynamics in wetlands and
open waters; modeling of wetland and open-water distributions; airborne
and space-borne assessment of CH4 emissions; role of wetlands and/or
water bodies in the global CH4 cycle under past and future climates;
synthesis studies of CH4 fluxes and controlling variables; remote
sensing of hydrologic dynamics and vegetation characterization in
wetlands and open waters; process studies of CH4 production, oxidation
and emission are welcome.

Session 3494: Climate Change and Nutrient Cycles of
High-Latitude Ecosystems
Conveners: Kyle Whittinghill, Tamara Harms, and Kate Buckeridge.
Session description: Despite strong nutrient limitation of primary
productivity at high-latitudes, less attention is paid to the effects of
climate change on nutrient cycling than to carbon cycling. Climate
change may alter nutrient cycles by altering disturbance and
precipitation regimes, vegetation communities, and thawing of permafrost
soils. Changes in availability of nutrients may have significant effects
on storage and release of carbon. In this session, conveners propose to
explore how changing climate alters nutrient dynamics in
permafrost-dominated ecosystems. Presentations on the cycling of N, P,
and other nutrients, especially those on disturbance effects,
terrestrial-aquatic linkages, and growing season controls on
productivity are welcome.

Session 2714: Carbon Cycling in Arctic and Subarctic Aquatic Systems
in a Changing Climate
Conveners: Kim Wickland, Suzanne Tank, and Jorien Vonk.
Session description: Aquatic systems are important locations for
receiving, processing, and transporting carbon, and are potential
sentinels of climate change effects. These systems are especially
vulnerable to climate change in Arctic and subarctic regions, where
hydrology and vegetation distribution are changing, wildfire disturbance
is common, and considerable amounts of carbon are stored in permafrost
soils that are subject to thaw. Impacts on and responses of Arctic and
subarctic aquatic system biogeochemistry are complicated, and diverse
approaches across multiple scales are needed to understand effects of
current and future climate change. This session will bring together
research on carbon delivery to aquatic systems and importance of
changing flowpaths, processing of C in aquatic systems, aquatic system
productivity, and fluvial exports to coastal zones and/or gaseous fluxes
to the atmosphere. Submissions that deal with all aspects of carbon
cycling in arctic and subarctic aquatic ecosystems, including field,
modeling, and remote sensing studies are welcome.

Session 3585: Results from a Decade+ of Arctic Ocean Network Observations
Conveners: Rick Krishfield, Jamie Morison, Andrey Proshutinsky,
and John Toole.
Session description: Pronounced and ongoing changes in the Arctic Ocean
have been documented since approximately 2000 by long-term oceanic
Arctic Observing Network (AON) programs such as the North Pole
Environmental Observatory, Beaufort Gyre Observational Program,
Ice-Tethered Profiler Project, An Ocean Observing System for the Bering
Strait and many others (see for example, data archived at the Advanced
Cooperative Arctic Data and Information Service at NSIDC). These data
provide an exceptional basis for analysis and synthesis of long-term
variations in the Arctic Ocean and overlying sea ice. The goals of our
proposed special session are to: report major results of observational
studies conducted by AON; analyze and synthesize important findings to
better understand the causes and mechanisms of changes; investigate
climatically induced transformations in key Arctic Ocean and sea ice
processes and parameterize their subgrid variability; and evaluate
representativeness and effectiveness of observing systems to monitor
rapidly changing climate conditions.

Session 2633: Changing Ecosystems of the Arctic and Antarctic
Conveners: Eileen Hofmann, Gus Shaver, and Jackie Grebmeier.
Session description: The terrestrial, freshwater, and oceanic
environments of the Arctic and Antarctic are undergoing considerable
modifications as a result of climate change. These changes are affecting
the structure and productivity of the ecosystems at the two poles, as
evidenced by changes in species range, shifts in timing and magnitude of
biological production, loss of some polar species, and establishment of
new species from subpolar regions. This session will provide a venue to
discuss these biological changes, compare the consequences to trophic
interactions, and explore the drivers that affect ecosystem variability
and change at both poles. Abstracts that consider projections of the
possible consequences of these changes for future productivity of high
latitude ecosystems and potential effects for resource usage are also
invited.

Session 3272: Removing Carbon Dioxide from Earth's Atmosphere
Conveners: Marcia McNutt, Jennifer Wilcox, and Edward Dunlea.
Session description: Human activities over the past centuries--mostly
fossil fuel burning and deforestation--have resulted in the release of
nearly two trillion tons of carbon dioxide (CO2), significantly
increasing concentrations in the atmosphere. Today, scientists,
engineers, and policy makers are working together to discover, validate,
and implement strategies to reduce CO2 emissions. However, given the
pace of emissions reductions, efforts to remove anthropogenic CO2 from
the atmosphere and sequester them may be necessary within the portfolio
of solutions to reduce negative climate-change impacts. This session
provides a venue to discuss various carbon dioxide removal techniques,
including bioenergy with carbon capture and sequestration, land
management (afforestation, reforestation, etc.), and ocean iron
fertilization. Abstracts that consider carbon reservoir properties and
carbon disposal are also invited.
