Description
The Greenland Environmental Observatory (GEOSummit) on the summit of the Greenland Ice Sheet (72°N, 38°W, 3200 m.a.s.l.) was established by the U.S. National Science Foundation (NSF) and the Danish Commission for Scientific Research in Greenland to provide year-round, long-term measurements for monitoring and investigations of the Arctic environment. The multidisciplinary facility is home to several year-round investigations as well as numerous seasonal campaigns which take advantage of the unique location of the observatory. GEOSummit provides investigators ease of access to the highest site north of the Arctic circle. Since 1989, when the GISP II ice-coring activities began, the site has hosted numerous atmospheric and glaciological investigations. Following two trial winter over periods (1997-1998, and 2000-2002), the NSF Long Term Observatory (LTO) program committed funding to maintain year-round measurements of key baseline variables of climate change at the site for a period of five years from 2003-2008. In addition, several programs funded through European agencies have a year-round presence at the site.
