"First Person": Examining Climate-Related Changes in the Arctic with an Eye Towards What is Yet to Come

10/29/2009 Biologist Eric Post talks about climate change in the Arctic and how some effects are so subtle as to be, for now, "like a thief in the night." More

From Climate Science to Ecology: NSF-funded LARISSA Takes an In-depth Look at the Collapse of a Massive Antarctic Ice Shelf

10/27/2009 The LARsen Ice Shelf System, Antarctica (LARISSA) project will conduct a uniquely in-depth and wide-ranging study of an ice-shelf ecosystem in the wake of the spectacular collapse of the Larsen B ice shelf. More

NOAA's Arctic Report Card: Changes Affecting Air, Ocean, and Everything in Between

10/22/2009 Despite the fact that summer 2009 had more sea ice than in 2007 or 2008, scientists are seeing drastic changes in the region from just five years ago and at rates faster than anticipated, according to NOAA's "Arctic Report Card." More

U.S. Fish and Wildlife Service Proposes Polar Bear Critical Habitat

10/22/2009 The U.S. Fish and Wildlife Service has announced a proposal to designate critical habitat for the polar bear, and will open a 60-day public comment period on the measure. More

Indiana School Welcomes Home NOAA ‘Teacher at Sea’ from Arctic Voyage of Discovery

10/20/2009 Christine Hedge, a 7th-grade science teacher who spent six weeks in the Arctic Ocean on board the U.S. Coast Guard icebreaker Healy, discovered an underwater mountain. More

National Ice Center Marks 2009 Arctic Sea Ice Minimum

10/16/2009 The National/Naval Ice Center (NIC) has concluded that the 2009 sea ice minimum, which occurred between Sept. 16 and 23, is the third lowest since 1979. More

"First Person": Researchers Discuss How Scientific Tools Yield a New Perspective on the Fates of Two Historic Polar Expeditions

10/8/2009 Writing in American Scientist, NSF-funded researchers describe how they used satellite ice measurements to examine the roles of luck and environment in the outcomes of Nansen's Fram expedition and Shackleton's Endurance voyage. More

NASA Ice Campaign Takes Flight in Antarctica

10/8/2009 Starting in November, NASA will fly missions in a DC-8--a 157-foot-long airborne laboratory--to study to study changes to Antarctica's sea ice, ice sheets, and glaciers as part of the agency's Operation Ice Bridge. More

Algae and Pollen from the Antarctic Geologic Drilling Program Sediment Core show Sudden Antarctic Warming Occurred in the Past

10/1/2009 Using samples from the multinational ANDRILL Program, NSF-funded researchers and their international colleagues now have evidence that a sudden warm period occurred in Antarctica about 15.7 million years ago and lasted for a few thousand years. More

Successful Flight of University of Kansas' Unmanned Aircraft Promises to Enhance Polar Climate-Change Research

9/9/2009 An innovative unmanned aircraft conceived and built at the NSF-funded Center for Remote Sensing of Ice Sheets recently passed its first flight test, a crucial step toward gathering better data at slower speeds and lower altitudes over icy terrain. More
