Earth's Climatic History Was Written In Dust
2014-01-25 05:28:19

April Flowers for redOrbit.com - Your Universe Online Polarstern, a research icebreaker, returned from the South Pacific in 2010 with a scientific treasure. The treasure, described in a recent issue of Science, consisted of ocean sediments from a previously almost unexplored part of the South Polar Sea. To geological history researchers, these inconspicuous mud samples are a valuable archive from which they can reconstruct the climatic history of the polar areas over many years of...

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...

Studies confirm that twice as much marine debris is lying on the seabed today compared to ten years ago The sea bed in the Arctic deep sea is increasingly strewn with litter and plastic waste.  As reported in the advance online publication of the scientific journal Marine Pollution Bulletin by Dr. Melanie Bergmann, biologist and deep-sea expert at the Alfred Wegener Institute for Polar and Marine Research in the Helmholtz Association. The quantities of waste observed at the AWI...

Polarstern Has News About Arctic Sea Ice
2012-10-11 18:43:41

Alan McStravick for redOrbit.com — Your Universe Online The Polarstern expedition has disconcerting news about our rapidly receding sea ice. The Polarstern, an ice-breaking research vessel, returned to the port of Bremerhaven two days ago. The Polarstern, operating on behalf of the Alfred Wegener Institute, was conducting research into the retreat of sea ice and the impact it will have on the Arctic Ocean and its ecosystems over the last two months. In all, 54 researchers and...

Why did the atmosphere contain so little carbon dioxide (CO2) during the last Ice Age 20,000 years ago? Why did it rise when the Earth's climate became warmer? Processes in the ocean are responsible for this, says a new study based on newly developed isotope measurements. This study has now been published in the scientific journal "Science" by scientists from the Universities of Bern and Grenoble and the Alfred Wegener Institute for Polar and Marine Research in the Helmholtz Association....

Elephant Seals Forced To Dive Deeper Due To Ocean Warming
2012-02-10 04:47:00

Global warming is having an effect on the dive behavior and search for food of southern elephant seals. Researchers from the Alfred Wegener Institute for Polar and Marine Research in the Helmholtz Association cooperating in a joint study with biologists and oceanographers from the Universities of Pretoria and Cape Town have discovered that the seals dive deeper for food when in warmer water. The scientists attribute this behavior to the migration of prey to greater depths and now wish to...
