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:
- SESSION 25352: Drivers and Implications of Recent Changes in Arctic
Greening and Browning
Conveners: Larry D. Hinzman, Howard E. Epstein, and Natalie Boelman.
Invited Speaker: Uma Bhatt, University of Alaska Fairbanks.
Remote sensing observations of the Arctic show recent and complex changes
in tundra vegetation. For many decades, a trend toward greener vegetation
("Arctic greening") was observed across the circumpolar region. Recently
however, greater variability in the extent of greening has been seen and
decreases in vegetation ("Arctic browning") have been observed in some
regions in some years. The drivers of this increased variability in
greening versus browning among years and across the landscape is currently
poorly understood. Expansive changes in tundra vegetation could have strong
implications for the surface energy balance and climate change in the
Arctic, as well as impacts on permafrost thaw, carbon cycling, hydrological
processes, vegetation composition, and biota. This session solicits
abstracts on the underlying drivers and the potential impacts of Arctic
greening and browning, and abstracts that discuss the research needed to
continue to advance our scientific understanding of this topic.

- SESSION 26064: Understanding Ice Sheet Surface Melt
Conveners: John Cassano, Sarah Das, Sridhar Anandakrishnan, and Lauren
Everett.
Runoff from Greenland surface melt contributes a large fraction of the ice
sheet's ongoing mass loss, and surface melt-induced processes such as
hydrofracture and ice cliff failure have the potential to lead to
additional large future ice losses from the Antarctic ice sheet. Our
understanding of the factors driving surface melt at both poles, as well as
how surface melt impacts ice dynamics, is limited by a short observation
period, high spatial and temporal variability, and a complex set of
dynamics between the atmosphere, ocean, and ice sheet. Unraveling these
complex relationships is necessary for advancing our ability to understand
ice sheet mass balance and predict its future impact on sea level rise.
Abstracts are requested for this session on improving our understanding of
ice sheet surface melt variability and dynamics, including how surface melt
and surface melt-induced processes are observed, quantified, and modeled in
the past, present and future.

- SESSION 29503: Runoff Generation in Snow Dominated Regions: Connecting
Seasonal Snowpacks and Streamflow Response
Conveners: Ryan Webb, Graham A. Sexstone, Jessica M. Driscoll, and Juan
Ignacio Lopez.
Over a billion people worldwide rely on water resources that are derived
from snow in mountainous regions. Understanding both the volume of water
stored in seasonal snowpacks and its subsequent runoff generation is vital
for improved water resource management and planning in these regions.
Advances in field measurements, remote sensing observations, and modeling
capabilities are critical for linking snowpack information with streamflow
response and particularly pertinent to understand how changing snow
dynamics will impact future water infrastructure and supply. This session
seeks to explore the allocation of snowmelt to various hydrological
processes including overland flow, shallow subsurface flow, groundwater
recharge, evapotranspiration, and hydrograph separation between the various
streamflow components. Organizers invite submissions focusing on the
connection between seasonal snowpacks and streamflow response through an
improved understanding of runoff generation processes, from the catchment
to continental scale.
