Has Antarctic Sea Ice Expansion Been Overestimated?

European Geosciences Union (EGU) New research suggests that Antarctic sea ice may not be expanding as fast as previously thought. A team of scientists say much of the increase measured for Southern Hemisphere sea ice could be due to a...

Scientists Tracking Breakup Of Arctic Summer Sea Ice
2014-07-17 03:27:40

By Hannah Hickey, University of Washington As sea ice begins to melt back toward its late September minimum, it is being watched as never before. Scientists have put sensors on and under ice in the Beaufort Sea for an unprecedented campaign to monitor the summer melt. The international effort hopes to figure out the physics of the ice edge in order to better understand and predict open water in Arctic seas. "This has never been done at this level, over such a large area and for such...

West Antarctic Ice Sheet
2014-07-12 06:07:29

redOrbit Staff & Wire Reports - Your Universe Online Much of the climate change-related research published recently has focused on the impact of warming temperatures on the West Antarctic ice sheet – but what is it about this region that causes scientists to be so interested in it? According to the US National Oceanic and Atmospheric Administration (NOAA), the West Antarctic ice sheet contains two major slabs of frozen water (the Ronne and Ross Ice Shelves), as well as several...

West Antarctica's Thwaites Glacier Is Melting Due To Geothermal Heat
2014-06-10 10:18:21

Gerard LeBlond for redorbit.com - Your Universe Online Researchers from the Institute for Geophysics at The University of Texas at Austin (UTIG) have discovered that Thwaites Glacier is being eroded by the ocean, as well as being melted from geothermal heat. Their findings are published in the current edition of the Proceedings of the National Academy of Sciences (PNAS). Accurate information from beneath the West Antarctic Ice Sheet has previously been inaccessible, but new findings of...

Melting Arctic Sea Ice Opens New Passages For Invasive Species
2014-05-28 03:24:06

Smithsonian Scientists say early action could protect coasts For the first time in roughly 2 million years, melting Arctic sea ice is connecting the north Pacific and north Atlantic oceans. The newly opened passages leave both coasts and Arctic waters vulnerable to a large wave of invasive species, biologists from the Smithsonian Environmental Research Center assert in a commentary published May 28 in Nature Climate Change. Two new shipping routes have opened in the Arctic: 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...

National Snow and Ice Data Center Will next year’s summer Arctic ice extent be high or low? Can ship captains plan on navigating the famed Northwest Passage — a direct shipping route from Europe to Asia across the Arctic Ocean — to save on time and fuel? A new study says year-to-year forecasts of the Arctic’s summer ice extent are not yet reliable. Scientists at the National Snow and Ice Data Center (NSIDC), University College London, University of New Hampshire and University...

Warm Rivers Play A Role In Arctic Sea Ice Melt
2014-03-06 06:32:21

Brett Smith for redOrbit.com - Your Universe Online According to a new study from NASA researchers, warm river waters draining into the Arctic Ocean are adding to the melting of sea ice in the Arctic Ocean each summer. Published in the journal Geophysical Research Letters, researchers reported on an abrupt inflow of warm river water into the Arctic Ocean that swiftly warmed the top layers in the sea, fueling the melting of summer ice. “River discharge is a key factor contributing...

Arctic Sea Ice Trends

April Flowers for redOrbit.com - Your Universe Online According to new research from the University College London, the melt season across the Arctic is getting longer by five days every ten years. Julienne Stroeve, Professor of Polar Observation and Modeling at UCL Earth Sciences, led the team in analyzing satellite data. The analysis, published in Geophysical Research Letters, revealed that the Arctic Ocean is absorbing even more of the sun’s energy in summer, leading to an even...

Antarctic ice shelf
2014-03-03 05:04:27

McGill University In the mid-1970s, the first available satellite images of Antarctica during the polar winter revealed a huge ice-free region within the ice pack of the Weddell Sea. This ice-free region, or polynya, stayed open for three full winters before it closed. Subsequent research showed that the opening was maintained as relatively warm waters churned upward from kilometers below the ocean's surface and released heat from the ocean's deepest reaches. But the polynya -- which...

Adelies Ross Sea ice floes
2014-02-27 05:21:14

April Flowers for redOrbit.com - Your Universe Online The Ross Sea is a major, biologically productive ecosystem in the Antarctic, which "clearly will be extensively modified by future climate change" in the coming decades as longer periods of ice-free open water are created by rising temperatures and changing wind patterns. According to a new paper funded by the National Science Foundation (NSF), these ice-free periods affect the life cycles of both predators and prey. The research...

Arctic Ocean
2013-04-18 22:31:23

The Arctic Ocean which is located in the Northern Hemisphere and mostly in the Arctic north polar region, is the shallowest and smallest of the world’s five major oceanic divisions. The International Hydrographic Organization recognizes it as an ocean, although, some oceanographers consider it as the Arctic Mediterranean Sea or simply, the Arctic Sea, classifying it a Mediterranean sea or an estuary of the Atlantic Ocean. Alternatively, the Arctic Ocean can be considered as the northernmost...
