Latest Glaciology Stories
One hundred and two years ago, the Titanic set off on its fateful maiden voyage from the United Kingdom. Coinciding with that anniversary is a new report that has determined the conditions surrounding the iceberg that would eventually take 1,517 lives.
A new study led by Lance Lesack, a Simon Fraser University geographer and Faculty of Environment professor, has discovered unexpected climate-driven changes in the mighty Mackenzie River’s ice breakup.
Scientists studying the behavior of the world's ice sheets--and the future implications of ice sheet behavior for global sea-level rise--may soon have a new airborne tool that will allow radar measurements that previously would have been prohibitively expensive or difficult to carry out with manned aircraft.
Will next year’s summer Arctic ice extent be high or low? Can ship captains plan on navigating the famed Northwest Passage — a direct shipping route from Europe to Asia across the Arctic Ocean — to save on time and fuel? A new study says year-to-year forecasts of the Arctic’s summer ice extent are not yet reliable.
Six massive glaciers in West Antarctica are moving faster than they did 40 years ago, causing more ice to discharge into the ocean and global sea level to rise, according to new research.
Using sediments from a remote lake, researchers from Brown University have assembled a 60,000-year record of rainfall in central Indonesia. The analysis reveals important new details about the climate history of a region that wields a substantial influence on the global climate as a whole.
British researchers who typically study polar moss samples because they provide indications of past climate conditions have found that Antarctic moss can survive trapped under ice for over 1,500 years.
The last stable section of the Greenland ice sheet is receding and now considered unstable – a development that could portend even more ice loss in the future and significant sea level rise.
Using a cutting-edge research technique, UCLA researchers have reconstructed the temperature history of a region that plays a major role in determining climate around the world.
Scientists working on NASA’s Operation IceBridge mission are en route to Greenland to kick off this year’s Arctic land and sea ice data collection efforts, officials from the US space agency announced on Wednesday.
The Columbia Plateau ecoregion is a Level III ecoregion designed by the United States Environmental Protection Agency in the U.S. states of Oregon and Washington, with little areas over the Washington state border in Idaho. This ecoregion stretches across a wide swath of the Columbia River Basin from the Dalles, Oregon to Lewiston, Idaho to Okanogan, Washington near the Canadian border. It incorporates nearly 500 miles of the Columbia River, as well as the lower reaches of major tributaries....
The Arctic Ocean which is located in the Northern Hemisphere and mostly in the Arctic north polar region, is the shallowest and smallest of the world’s five major oceanic divisions. The International Hydrographic Organization recognizes it as an ocean, although, some oceanographers consider it as the Arctic Mediterranean Sea or simply, the Arctic Sea, classifying it a Mediterranean sea or an estuary of the Atlantic Ocean. Alternatively, the Arctic Ocean can be considered as the northernmost...
Meltwater is water that is released from melting snow or ice. This includes meltwater from glacial ice and ice shelves over oceans. Meltwater is often produced during volcanic eruptions, and can cause dangerous lahars (landslides of wet volcanic debris). When meltwater pools on the surface rather than draining or flowing away, it forms pools known as melt ponds. Meltwater will often refreeze as the temperature drops. Meltwater can also collect or melt under the ice's surface. Sub-glacial...
- Having no light.
- Of or relating to the region of a body of water that is not reached by sunlight and in which photosynthesis is unable to occur.
