Latest Glacial landforms Stories
You might think that the noisiest parts of Earth’s oceans are the shipping lanes near busy American or European ports, but you’d be wrong. Thanks to rapidly melting, shearing and calving ice sheets, the waters near Alaska and Antarctica are actually the noisiest waters known to man, according to a new study in Geophysical Research Letters.
Ice loss from the Greenland Ice Sheet has increased four-fold over the past four decades, and scientists now report that oceans play a vital role in how quickly the ice sheet will melt and how much total mass will be lost.
Trapped air bubbles squirting out of disappearing glacial ice causes a sizzling noise that might provide clues to the rate of glacier melt and help researchers better monitor the fast-changing polar environments.
Once thought to be a major contributor to sea-level rise, a new study indicates glacial melt water was found to have only a minor effect on sea levels.
Lakes often form on top of a glacier and drain onto the bedrock below, lubricating a glacier's movements as a result. A new study from an international group of researchers has found the way these lakes drain can affect the velocity, extent and direction of a glacier's progress.
While using a innovative radar analysis method to accurately image the subglacial water system under West Antarctica's Thwaites Galcier, scientists discovered a swamp-like canal system beneath the ice.
All living organisms rely on iron as an essential nutrient. In the ocean, iron’s abundance or scarcity means all the difference as it fuels the growth of plankton, the base of the ocean’s food web.
Antarctica's topography began changing from flat to fjord-filled starting about 34 million years ago, according to a new report from a University of Arizona-led team of geoscientists.
The high elevation flat surfaces characteristic of the Norwegian landscape are in geologically terms young, according to a paper in Nature Geoscience.
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...
