redOrbit Staff & Wire Reports - Your Universe Online A team of 74 scientists from 18 countries, mostly working on an unpaid volunteer basis, have mapped and catalogued nearly 200,000 glaciers, creating the first-ever global inventory of icebergs and ice floes. The catalogue, which was compiled as part of the Randolph Glacier Inventory (RGI) project, includes information about locations and size. It will allow for calculations of volume, as well as their ongoing contributions to...

Wilkes Basin in East Antarctica
2014-05-06 05:46:34

April Flowers for redOrbit.com - Your Universe Online A new study from the Potsdam Institute for Climate Impact Research (PIK) reveals that a persistent ice discharge into the ocean could be triggered by the melting of just a small volume of ice on East Antarctica's shore. Such a persistent discharge could result in unstoppable sea level rise for thousands of years to come, according to computer simulations of the Antarctic ice flow using improved data of the ground profile underneath the...

Ancient Landscape Found Beneath Greenland Ice Sheet
2014-04-18 11:47:38

[ Watch The Video: Ancient Soil Found Under Greenland Ice Sheet ] By Joshua E. Brown, University of Vermont Glaciers are commonly thought to work like a belt sander. As they move over the land they scrape off everything—vegetation, soil, and even the top layer of bedrock. So scientists were greatly surprised to discover an ancient tundra landscape preserved under the Greenland Ice Sheet, below two miles of ice. "We found organic soil that has been frozen to the bottom of the...

Researchers Decipher Climate Paradox From The Miocene Using Complex Model Simulations
2014-04-14 12:34:00

AWI Scientists of the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI), have deciphered a supposed climate paradox from the Miocene era by means of complex model simulations. When the Antarctic ice sheet grew to its present-day size around 14 million years ago, it did not get colder everywhere on the Earth, but there were regions that became warmer. A physical contradiction? No, as AWI experts now found out, the expansion of the ice sheet on the Antarctic...

Measuring Changes In Polar Ice Sheets Using Unmanned Aircraft
2014-04-03 09:22:14

[ Watch The Video: Researchers Test Drones To Monitor Antarctic Ice ] National Science Foundation Boldly going where larger, human-piloted planes cannot, they promise to close a key gap in knowledge for climate modelers Scientists studying the behavior of the world's ice sheets--and the future implications of ice sheet behavior for global sea-level rise--may soon have a new airborne tool that will allow radar measurements that previously would have been prohibitively expensive or...

Greenland river discharge
2014-03-19 03:59:06

redOrbit Staff & Wire Reports - Your Universe Online After growing frustrated attempting to measure the amount of water draining from Greenland’s melting ice sheet, one UCLA graduate student has developed a new method of measuring the width of a river over an extended period of time using freely available imagery from orbiting satellites. Currently, the volume of water running through a river at any given time is determined using a series of ground-based measurements. Hydrologists...

pine island glacier
2014-02-21 04:41:24

redOrbit Staff & Wire Reports - Your Universe Online Previous instances of rapid thinning of Pine Island Glacier suggests that current ice loss in the Antarctic could continue for several more decades, a team of geologists from the US, UK and Germany report in this week’s edition of the journal Science. Pine Island Glacier, which is part of the West Antarctic Ice Sheet, is rapidly accelerating, thinning and retreating, and the researchers report that it has thinned rapidly in the...

Greenland Ice Sheet
2014-02-07 04:35:58

Lee Rannals for redOrbit.com - Your Universe Online Researchers writing in the journal Nature say that ocean warming could be causing a four-fold increase in ice loss on the Greenland Ice Sheet. The Greenland Ice Sheet is about a 2-mile thick layer of ice that covers the country. Glaciers that drain the ice sheet plunge into coastal fjords that are about 2,000 feet deep, helping to expose the ice sheet edges that contact the ocean. Oceanographers from Woods Hole Oceanographic...

NASA To Map Iceland's Winter Glaciers With High-Precision Radar
2014-01-29 06:05:22

April Flowers for redOrbit.com - Your Universe Online This week, a high-precision radar instrument from NASA's Jet Propulsion Laboratory (JPL) left for Iceland to create detailed maps of how glaciers move in the dead of winter. These maps will aid scientists in understanding some of the most basic processes involved in melting glaciers, which are major contributors to rising sea levels. The instrument—developed by JPL and flying on a NASA research aircraft—departed from NASA's...

Climatic Variability Has A Significant Impact On Pine Island Glacier
2014-01-03 07:31:08

redOrbit Staff & Wire Reports - Your Universe Online Pine Island Glacier, one of the largest routes for ice to flow from Antarctica into the sea, is far more susceptible to climatic and ocean variability than previously believed, according to research published Thursday in the advanced online version of the journal Science. Observations from Dr. Pierre Dutrieux of the British Antarctic Survey (BAS) and his colleagues showed sizable fluctuations in ocean heat in Pine Island Bay. They...


Word of the Day
endocarp
  • The hard inner (usually woody) layer of the pericarp of some fruits (as peaches or plums or cherries or olives) that contains the seed.
This word comes from the Greek 'endon,' in, within, plus the Greek 'kardia,' heart.
