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....

Glass Sponge Community Thrives Despite Antarctic Ice Loss
2013-07-11 18:53:49

Brett Smith for redOrbit.com - Your Universe Online The waters around Antarctica can be an inhospitable place, but a new study has shown that dynamic events in the region are constantly shaping and even boosting the ecosystems in the Southern Ocean. The study, published in Current Biology, reports on a surprisingly prolific community of glass sponges colonizing an area formerly covered by permanent ice - surprising because the sponges live long, slow lives that can extend up to 10,000...

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...

According to a press release from Europe´s Space administration (ESA) part of Antarctica´s ice sheet has increased in height. These findings come from the ESA´s ice-measuring satellite, CryoSat. According to the ESA, these findings not only provide good news from the ice sheets, but also show the effectiveness of their CryoSat missions. According to their website, ESA.int, CryoSat is Europe´s first mission to address the thickness of land and sea ice and how this...

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...

Image 1 - Link Found Between Summer Arctic Sea Ice Cover And Winter Weather In Central Europe
2012-02-02 08:04:05

Even if the current weather situation may seem to speak against it, the probability of cold winters with much snow in Central Europe rises when the Arctic is covered by less sea ice in summer. Scientists of the Research Unit Potsdam of the Alfred Wegener Institute for Polar and Marine Research in the Helmholtz Association have decrypted a mechanism in which a shrinking summertime sea ice cover changes the air pressure zones in the Arctic atmosphere and impacts our European winter weather....

Image 1 - Antarctic Expedition Checks CryoSat Data
2011-12-10 04:41:07

Next week marks 100 years since Roald Amundsen reached the South Pole. As a team of scientists brave the Antarctic to validate data from ESA´s CryoSat mission, it´s hard to imagine what these first intrepid explorers would have thought of today´s advances in polar science. The remote and vast expanse of the Antarctic is arguably the most hostile environment on Earth — infamously claiming the lives of Captain Robert Scott and his party all those years ago in their fated...

The end of the last ice age and the processes that led to the melting of the northern and southern ice sheets supply basic information on changes in our climate. Although the maximum size of the ice sheet in the northern hemisphere during the last ice age is relatively well known, there is little reliable data on the dimensions of the Antarctic ice sheet. A publication appearing in the journal “Science” on 1 December now furnishes indications that the two hemispheres attained...

Alfred Lothar Wegener (November 1, 1880 "“ November 2, 1930) was a German scientist, geologist, and meteorologist. He is best known for establishing the theory of the continental drift. His 1915 theory of continental drift surmised that the continents were slowly floating around the Earth. Most of his basis was strictly circumstantial evidence, and further he was not able to exhibit a mechanism for continental drift, which resulted in an unaccepted hypothesis until the 1950s. At that...

tesla
  • The unit of magnetic flux density in the International System of Units, equal to the magnitude of the magnetic field vector necessary to produce a force of one newton on a charge of one coulomb moving perpendicular to the direction of the magnetic field vector with a velocity of one meter per second. It is equivalent to one weber per square meter.
This word is named for Nikola Tesla, the inventor, engineer, and futurist.
