digital elevation models for Greenland and Antarctica
2014-08-21 06:00:57

April Flowers for redOrbit.com - Your Universe Online Data from the European Space Agency's (ESA) CryoSat-2 spacecraft has been used to map elevation and elevation changes in both Greenland and Antarctica by a team of researchers from the Alfred Wegener Institute (AWI) in Germany. The new maps, which are the most complete to ever be created from a single satellite mission, reveal the ice sheets are losing volume at an unprecedented yearly rate (approximately 500 cubic kilometers). The...

Finding Deepest Iceberg Scours To Date Provides New Insights Into Arctic’s Glacial Past
2014-08-13 03:02:09

Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research Scientists from the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI), have found between Greenland and Spitsbergen the scours left behind on the sea bed by gigantic icebergs. The five lineaments, at a depth of 1,200 meters, are the lowest-lying iceberg scours yet to be found on the Arctic sea floor. This finding provides new understanding of the dynamics of the Ice Age and the extent of...

Key To Adaptation Limits Of Ocean Dwellers Uncovered By Scientists
2014-07-02 03:35:33

Alfred Wegener Institute The simpler a marine organism is structured, the better it is suited for survival during climate change. Scientists of the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research, discovered this in a new meta-study, which appears today in the research journal Global Change Biology. For the first time biologists studied the relationship between the complexity of life forms and the ultimate limits of their adaptation to a warmer climate. While...

The high cliffs of Eastern Siberia – which mainly consist of permafrost – continue to erode at an ever quickening pace. This is the conclusion which scientists of the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research have reached after their evaluation of data and aerial photographs of the coastal regions for the last 40 years. According to the researchers, the reasons for this increasing erosion are rising summer temperatures in the Russian permafrost regions as...

Pleistocene Ice Sheet Evidence Uncovered
2013-10-01 04:53:02

April Flowers for redOrbit.com - Your Universe Online Traces of large ice sheets from the Pleistocene on a seamount off the north-eastern coast of Russia have been discovered by a team of geologists and geophysicists from the Alfred Wegener Institute (AWI) Helmholtz Centre for Polar and Marine Research. For the first time, these traces confirm that within the last 800,000 years in the course of ice ages, ice sheets more than approximately a mile thick also formed in the Arctic Ocean....

Long-term Data Reveal Deep Greenland Sea Warming Faster Than The Global Ocean
2013-09-25 12:53:48

Alfred Wegener Institute Recent warming of the Greenland Sea Deep Water is about ten times higher than warming rates estimated for the global ocean. Scientists from the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research recently published these findings in the journal Geophysical Research Letters. For their study, they analyzed  temperature data from 1950 to 2010 in the abyssal Greenland Sea, which is an ocean area located just to the south of the Arctic Ocean....

New AWI Thermal Imaging System Helps Researchers Protect Large Whales From Noise Around The Clock
2013-08-13 08:19:35

Helmholtz Association Pile driving during construction of wind farms and the use of airguns when searching for oil and gas unavoidably result in noise pollution in the surrounding area. To ensure that marine mammals are not harmed when in the close vicinity of these activities, regulatory authorities request so-called mitigation measures for their protection. One of such measures requires airguns to be switched off or pile driving to be stopped when whales approach the respective sound...

For Antarctic Clams Age Matters
2013-04-19 09:03:56

April Flowers for redOrbit.com - Your Universe Online According to a new study from the British Antarctic Survey (BAS), the University of Kiel, and the Alfred Wegener Institute, age matters for Antarctic clams when it comes to adapting to the effects of climate change. The study, published in the journal Global Change Biology, provides new insights into the likely impact that predicted environmental change could have on the future of ocean biodiversity. The Antarctic clam (laturnula...

New Chart Shows Entire Topography Of Antarctic Seafloor In Detail
2013-04-09 15:10:20

Alfred Wegener Institute for Polar and Marine Research Reliable information on the depth and floor structure of the Southern Ocean has so far been available for only few coastal regions of the Antarctic. An international team of scientists under the leadership of the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research, has for the first time succeeded in creating a digital map of the entire Antarctic seafloor. The International Bathymetric Chart of the Southern Ocean...

Arctic Melt Ponds Are Forcing Rapid Sea Ice Loss
2013-01-18 15:16:11

Brett Smith for redOrbit.com - Your Universe Online Melt ponds, a favorite phenomenon among arctic photographers, are turquoise or dark blue pools of water that appear on ice floes during the Arctic summer. According to a new report in Geophysical Research Letters, scientists from the Alfred Wegener Institute (AWI) have been observing more and more melt ponds atop one-year ice floes, instead of meter-thick, multi-year ice that used to dominate, even during the warmest months in the...
