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.
Last month the extent of sea ice covering the Arctic Ocean declined to the second-lowest extent on record, narrowly avoiding a new low.
NASA-funded researchers have created the first complete map of the speed and direction of ice flow in Antarctica.
Scientists observed for the first time the power of an earthquake and tsunami to break off large icebergs a hemisphere away.
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.
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.
The Greenland and Antarctic ice sheets are losing mass at an accelerating pace, according to a new NASA-funded satellite study.
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.
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).
A NASA analysis of satellite data challenges previously held beliefs about how the Arctic loses its older and thicker 'multiyear' sea ice.
Sea ice has reached its minimum extent for 2010, measuring in at the third-lowest extent since satellite measurements began.
While the 2010 minimum extent of arctic sea ice remains to be seen, NASA's Aqua satellite captured this snapshot on Sept. 3.
A new NASA satellite image shows the continued movement of a massive iceberg that broke off Greenland's Petermann Glacier on Aug. 5.
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.
"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.
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.
During the ICESCAPE voyage to the Arctic, scientists have been looking at the phytoplankton in the Arctic's Chukchi Sea -- how many, how big and at what depths they are found.
Jakobshavn Glacier shed 2.7 square miles of ice overnight as researchers watched the ice sheet rift and then retreat.
ICESCAPE has brought together a team of ice and ocean experts in the fields of biology, chemistry and physics to collect data across the sea in an effort to piece together the plankton picture.
The expedition got underway this morning as the U.S. Coast Guard icebreaker Healy steamed out of this island fishing port in the North Pacific.
