The Science Coordination Office (SCO) for the Greenland Environmental
Observatory at Summit will be hosting an informational seminar for
current and potential researchers as a splinter meeting at EGU. All
interested parties are encouraged to attend. Information regarding the
logistical capabilities, science capabilities, and future planning of
the research platform will be presented. Individuals from the SCO and
NOAA will be available to answer questions.
Research at GEOSummit focuses on glaciological processes including
air-snow exchange of reactive atmospheric compounds, mass balance
studies of the ice sheet, and boundary layer meteorology. Furthermore,
the station provides an ideal test bed facility for ground truthing and
testing of remote sensing platforms. Recent studies at the site have
included the testing of radars, remotely operated vehicles, and
robotics.
BACKGROUND
The Greenland Environmental Observatory at Summit (GEOSummit) is a
year-round arctic sampling station funded by the U.S. National Science
Foundation with cooperative agreements between the Danish Polar Centre
and the Greenland Home Rule Government. GEOSummit is located at the top
of the Greenland Ice Sheet (72o N, 38o W) and provides unique
opportunities for investigation of atmospheric and glaciological
processes.
In 1993 the GISP2 drilling project completed drilling 3054 m. of ice.
Beginning the following year and continuing to the present, intensive
field campaigns were conducted at the site to characterize the
atmosphere-to-firn dynamics in order to enable more comprehensive
analysis of the ice core record. A baseline measurement program was
established in 2003 to provide year round measurements of key
site-specific variables.
Currently the suite of baseline measurements available to researchers
includes station meteorology, accumulation measurements from a 100-stake
array and a 12 km transect, weekly surface snow chemistry, monthly snow
pit chemistry and stratigraphy, and filter sampled radionuclides. Also
available are aerosols measured continuously with an eight-drum impactor
sampler. NOAA Climate Monitoring and Diagnostics Laboratory (NOAA-CMDL)
instrumentation is on site to provide continuous ozone, black carbon,
carbon cycle gas, and greenhouse gas sampling contributing to the Global
Atmospheric Watch (GAW) program. Flasks are collected weekly for carbon
cycle gasses and halocarbon flasks are collected bi-weekly.
