International Team to Drill Beneath Massive Antarctic Ice Shelf
11.09.11 - A multidisciplinary, international team of researchers is heading this month to an isolated edge of Antarctica, Pine Island Glacier, to determine how the ocean is melting away the glacier’s underbelly.

Arctic Sea Ice Hits 2nd-Lowest Level
10.04.11 - Last month the extent of sea ice covering the Arctic Ocean declined to the second-lowest extent on record, narrowly avoiding a new low.

Glacier Loss Detailed After Ice Shelves Collapse
07.25.11 - An international group of scientists has detailed glacier ice loss following the collapse of the Larsen A and B ice shelves in 1995 and 2002.

NASA Sets Sail on Mission's Final Arctic Voyage
06.21.11 - Scientists embark this week on the second and final leg of a NASA oceanographic field campaign to study how changing conditions in the Arctic affect the ocean's chemistry and ecosystems.

NASA's Arctic Ice Campaign Adds Second Aircraft
04.21.11 - NASA scientists conducting an airborne Arctic campaign to monitor changes in sea ice and ice sheet thickness have a new tool -- a second aircraft.

NASA Finds Polar Ice Adding More To Rising Seas
03.08.11 - The Greenland and Antarctic ice sheets are losing mass at an accelerating pace, according to a new NASA-funded satellite study.
-
Melting Snow and Ice Warm Northern Hemisphere →
02.24.11 - Mark Flanner at the University of Michigan and his collaborators used satellite data to measure how much changes in snow and ice in the Northern Hemisphere have contributed to rising temperatures in the last 30 years.
-
Record Low Arctic Sea Ice Extent for January →
02.09.10 - The U.S. National Snow and Ice Data Center (NSIDC) has reported that Arctic sea ice was at its lowest extent ever recorded for January (since satellite records began).
-
Channel Beneath Pine Island Glacier →
01.20.10 - Beneath the Pine Island Glacier in Antarctica, scientists have found a deepwater channel -- a likely pathway for warm water to reach the glacier’s underbelly and melt it from below.

Unstable Antarctica: What's Driving Ice Loss?
12.15.10 - New studies reveal mechanisms driving ice loss in West Antarctica, with implications for improving predictions of sea level rise.
-
The Role of Melt in Loss of Old Arctic Sea Ice
11.09.10 - A NASA analysis of satellite data challenges previously held beliefs about how the Arctic loses its older and thicker 'multiyear' sea ice.
-
Arctic Sea Ice Reaches 2010 Minimum Extent
10.06.10 - Sea ice has reached its minimum extent for 2010, measuring in at the third-lowest extent since satellite measurements began.

NASA Releases New Image of Massive Greenland Iceberg
08.12.10 - A new NASA satellite image shows the continued movement of a massive iceberg that broke off Greenland's Petermann Glacier on Aug. 5.
-
Ice Island Calves off Petermann Glacier
08.09.10 - A chunk of ice some 97 square miles in size broke off Greenland's Petermann Glacier on August 5. The resulting iceberg is the Arctic's largest since 1962.

Cutting Into Arctic Sea Ice
07.23.10 - "Over by the fish, below the soccer field," said ice scientist Bonnie Light, pointing at the Arctic sea ice from the bridge of the U.S. Coast Guard Cutter Healy earlier this month during NASA's ICESCAPE oceanographic mission.
-
Antarctica Traced from Space
07.22.10 - The point where ice separates from land is called the "grounding line." For scientists, an accurate map of the grounding line is a first step toward a complete calculation of how much ice the continent is losing.
