Significant Iron Contributed To North Atlantic Ocean By Glaciers
2013-03-11 12:23:52

Woods Hole Oceanographic Institution 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. A new study by biogeochemists and glaciologists at Woods Hole Oceanographic Institution (WHOI) identifies an unexpectedly large source of iron to the North Atlantic — meltwater from glaciers and ice sheets, which may stimulate plankton...

Global Sea-Level Rise Could Occur Unevenly Across Globe
2013-02-19 15:43:16

Peter Suciu for redOrbit.com — Your Universe Online The fact sea levels could rise if the polar ice caps melt has been long established, but according to new research some regions could see greater increases than others. According to research published in the journal Geophysical Research Letters, sophisticated computer modeling of sea-level rise over the coming century suggests parts of the Pacific could see the highest rates of rise while some polar regions will actually...

New Model Assesses Extent Of Sea Level Rise By 2100
2013-01-07 09:01:17

Lawrence LeBlond for redOrbit.com - Your Universe Online Two professors with the Intergovernmental Panel on Climate Change (IPCC) have taken on a new approach to assess future sea level rise due to the world´s melting ice sheets. Their study, published this week in Nature Climate Change, is the first of its kind to use structured expert elicitation (EE) along with an approach that mathematically pools other experts´ opinions to gain a clear picture on ice sheet melting....

West Antarctic Ice Sheet Warming Faster
2012-12-24 05:32:08

redOrbit Staff & Wire Reports - Your Universe Online A portion of the Antarctic ice sheet is warming nearly twice as quickly as experts had previously believed, which could increase the region's future contribution to rising sea levels, a team of researchers from the Ohio State University (OSU) has discovered. According to BBC News Environmental Correspondent Matt McGrath, the study authors analyzed temperature records from Byrd Station, a scientific outpost in the center of the...

Ocean Currents Helps Predict Arctic Sea Ice
2012-11-21 15:07:41

Lee Rannals for redOrbit.com - Your Universe Online Researchers at MIT have developed a new method for optimally combining models and observations of the Arctic Ocean to accurately simulate the seasonal extent of the ice change and the ocean circulation beneath. The Arctic Ocean freezes each winter to form sheets of sea ice that spread over millions of square miles. This ice then acts as a massive sun visor for the Earth and helps to reflect solar radiation and shield the planet from...

Rising Temperatures Could Lead To Sea Levels Rising Three Feet Or More
2012-11-15 13:56:59

April Flowers for redOrbit.com - Your Universe Online A rapid response between global temperatures and ice volume/sea-level that could lead to sea-levels rising by over 3 feet have been revealed by a new study from the University of Southampton. Global ice-volume variability has been one of the main feedback mechanisms in climate change during the last few million years. This is because of the strong reflective properties of large ice sheets. Scientists reconstruct ice volume...

NASA Studies Antarctic Sea Ice
2012-11-14 19:43:13

Alan McStravick for redOrbit.com — Your Universe Online A new study by NASA and the British Antarctic Survey tries to explain the increase of ice cover in the Antarctic that is seemingly contrary to the effects of climate change that have been witnessed over the previous two decades. In their report, they purport they have the first direct evidence that this increase in sea ice cover is due to changing winds that have had an impact on the changes to Antarctic sea ice drift. The...

Greenland Could Be Affected By Warming Temperatures
2012-11-14 09:01:27

April Flowers for redOrbit.com - Your Universe Online There are almost as many global climate models as there are climate scientists. Even with all of these models, however, it's very difficult to pin down how warming temperatures globally will affect any specific region. A research team from The City College of New York and the University of Liege, Belgium, and supported by the National Science Foundation (NSF), have made the "global local" using the output of three global models and...

Understanding Antarctic Ice Loss
2012-10-22 19:44:40

Alan McStravick for redOrbit.com — Your Universe Online Amazing GRACE. Scientists and researchers have some interesting news out of Antarctica. The rate of global sea level change has been fairly well-established. The understanding for exactly why this is occurring got a new wrinkle this past week. Utilizing the Gravity Recovery and Climate Experiment (GRACE) satellite data, a team was able to more accurately calculate the ice sheet mass loss by mapping and removing the mass changes...


Word of the Day
vermicular
  • Like a worm in form or movement; vermiform; tortuous or sinuous; also, writhing or wriggling.
  • Like the track or trace of a worm; appearing as if worm-eaten; vermiculate.
  • Marked with fine, close-set, wavy or tortuous lines of color; vermiculated.
