Project Summary
During the last two years joint Brazilian-Chilean-US collaborative effort focused on recovery a record that would show no evidence of melting or be compromised by of ice flow dynamic, and potentially cover time spin of at least 200 years. This international program of scientific collaboration and shared logistics provides an efficient way to investigate ongoing climate and glaciological changes impacting the Antarctic Peninsula. Our joint goal was to fill the gap of longer-term, high-resolution climate observations over the Antarctic Peninsula.
Snow sampling and shallow drilling was conducted during the February of 2007 at the Detroit Plateau, Antarctic Peninsula and following glaciochemical and stable isotope analyses confirmed that site potentially could be used for recovering a well preserved ice core record.
In October 2009 Rob Russell as part of collaboration of CECS with NASA and Johns Hopkins teams collected airborne radar data thatpoiint to potential ice thickness in the area from 240-560 m. Detailed results should be available in a few months. In November 2008 additional GPS survey, snow sampling and search of snow covered weather station was conducted. We are in the process of developed glaciochemical, stable isotopes time series that will be intercalibrate with weather station data, modern climate reanalysis and satellite data resulting in reconstructions of past climate (sea ice extent, airmass circulation, temperature, chemistry of the atmosphere, and accumulation rate). The resulting data set and interpretations will contribute to the Scientific Committee on Antarctic Research (SCAR) International Trans Antarctic Scientific Expedition (ITASE), to the International Partnership of Ice coring Sciences (IPICS), the IPY GLABENAP, Signals in Antarctica of past Global changes (SAGES), and to the interpretation of other Antarctic ice core records
