ice age. The Polar Meteorology Group also used the MM5 model to create what is called the Antarctic Mesoscale Prediction System (or AMPS). AMPS is a forecasting system used to make weather forecasts for Antarctica and the surrounding Southern Ocean in support of the United States Antarctic Program. Polar Rock Repository BPRC maintains a large, unique collection of geological samples and materials at the Polar Rock Repository. The PRR is a national facility that houses rock sample collections from Antarctica obtained by U.S. scientists over the past 40+ years. Dr. Anne Grunow is the curator of the Polar Rock Repository. It is the only facility of its kind in the United States. The facility has storage capacity of ~140,000 rock samples and more than 30,000 samples have been catalogued already. The sample collections are available for researchers, educators, and museums to use. An online database and educational materials are available to help educate the public about polar geology. Greenland field studies 1980s photogrammetrist Henry Brecher conducted aerial photographic surveys of major Greenland glaciers. 1990s Dr. Ellen Mosley-Thompson obtained ice cores from multiple locations, including GITS. Dr. Ken Jezek conducted radar studies in Greenland's accumulation and ablation zone. In 1995, Ken Jezek was at Swiss Camp. 2005 Jason Box assisted Konrad Steffen in automatic weather station maintenance at Swiss Camp and sites that comprise the Greenland Climate Network. Jason Box returned to Greenland to: 1.) obtain an ice core from a position in southeast Greenland where the Polar MM5 model simulates a maximum in snow accumulation, 2.) install time lapse cameras pointed at two outlet glaciers, and 3.) conduct supra-glacial melt lake measurements. 2007 In June, 2007, Jason Box established time lapse cameras beside 5 major west Greenland outlet glaciers. In July–September, Jason Box prepared for and occupied a camp near the Arctic Circle for 7 weeks during which time he conducted surface energy budget (melt) and supra-glacial melt lake measurements. 2008 During a 3-week field campaign, Jason Box, Ian Howat, Slawek Tulaczyk, and Yushin Ahn conducted measurements on Store Glacier, west Greenland. Ian Howat installed GPS sensors on Store Glacier in west Greenland. 2009 Jason Box installed time lapse cameras at Petermann Glacier in anticipation of a large area loss that eventually did occur August, 2010. 2010 April–May, 2010, Jason Box co-led a 750 km Arctic Circle Traverse across the southern Greenland ice sheet to obtain 3 ice cores and
