The goal of this project is to reconstruct the behavior of atmospheric circulation, specifically the Aleutian Low pressure system, over the past 10,000 years and to assess how its variability relates to past shifts in climate.

The research team will continue to explore remote regions of the seafloor around McMurdo Station, Antarctica with a recently developed remotely operated vehicle (ROV) for underwater research.

A team of researchers and technicians from the Center for Remote Sensing of Ice Sheets (CReSIS) spent two months documenting conditions at the West Antarctic Ice Sheet (WAIS) divide using a variety of techniques, including weather observations, GPS, ice coring, radar, and seismic sensing.

The expedition members will visit several research sites in Greenland as part of an initiative to foster enhanced international scientific cooperation between the countries. The expedition members will spend several days learning about the research conducted in Greenland, the logistics involved in supporting the research, and gain first-hand experience conducting experiments and developing inquiry-based educational activities. This year's work builds on the 2007, 2008, and 2009 expeditions and is supported by the National Science Foundation. The project was developed through cooperation with the U.S.-Denmark-Greenland Joint Committee, which was established in 2004 to broaden and deepen cooperation among the United States, the Kingdom of Denmark, and Greenland.

Team researchers will be investigating air-surface chemical interactions in the Arctic, and how these will evolve in future climates. Their efforts are part of the Ocean, Atmosphere, Sea Ice, Snowpack (OASIS) program—an international program that involves scientists from the United States, Canada, France, Germany, Italy, and the UK.
