  2. Program Solicitation in Antarctic Research



    The National Science Foundation (NSF) is accepting proposals for research supported by the United States Government in Antarctica. The goals of the program include expanding our fundamental knowledge of the region and using Antarctica as a platform from which to support research. Support is available for fieldwork and Antarctic-related analytical work at home organizations. Full proposals are due on June 8, 2009. Futher program information is available at: http://www.nsf.gov/pubs/2009/nsf09536/nsf09536.htm?govDel=USNSF_25

    Antarctica has long been a research site of interest for astrobiologists. The continent supports a range of unique organisms that can survive...

  3. Microbial Populations in Antarctic Permafrost


    Members of NAI’s Michigan State University Alumni Team are part of an international team of scientists characterizing the microbial populations in Antarctic permafrost soils. Based on multiple samples, they describe the presence of diverse populations of both aerobic and anaerobic bacteria, cyanobacteria, green algae, yeasts, and fungi. Based on the documented ages of the permafrost regions—perhaps more than 5 million years old—these findings represent the oldest viable microorganisms discovered in permafrost on Earth. Their paper appears in the April issue of Astrobiology.

  4. NAI Researchers Search for Meteorites in Antarctica


    Follow along as scientists from NAI’s University of Hawai’i Team go on expedition with the NSF/NASA – sponsored Antarctic Search for Meteorites (ANSMET) program. View photos, read about the team and their mission, and stay current with regular dispatches from the “Streets of McMurdo.” The ANSMET program enables researchers to collect meteorites in Antarctica first hand for scientific study. Over 75% of meteorites are recovered from Antarctica, and more than 15,000 samples have been supplied to over 400 scientists in 32 countries over the last 30 years.

  5. Arctic, Antarctic, Mars


    The city of Hammerfest lies at the northern tip of Norway, well above the Arctic Circle. If you board a ship heading north from there, just before you reach the polar ice cap you run into a group of islands known as the Svalbard archipelago.

    For the past two summers, a group of scientists has traveled to the largest of these islands to study an environment that sheds light on a notorious meteorite, discovered at the opposite end of the Earth, in Antarctica.

    The meteorite, ALH84001, began as a rather unremarkable piece of volcanic rock that formed about 4.5 billion...
