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...

Acidification Recorder Recovered From Antarctic Waters
2012-10-19 11:32:26

April Flowers for redOrbit.com - Your Universe Online A National Science Foundation (NSF) supported research team retrieved data from a sensor in Antarctic waters that they hope will provide critical baseline data for the acidification, or chemical changes, in those remote seas. Led by Gretchen Hofmann — professor of ecology, evolution and marine biology at the University of California, Santa Barbara (UCSB) — the all female team retrieved the sensor earlier this month...

NASA's Operation Ice Bridge Off To A Productive Start
2012-10-17 22:13:54

NASA's Operation IceBridge got the 2012 Antarctic campaign off to a productive start with a land ice survey of Thwaites Glacier and a sea ice flight over parts of the Bellingshausen Sea. During the first few weeks of a campaign, IceBridge typically concentrates on sea ice before it begins to melt as spring temperatures rise, but as often happens in the field, the weather had other ideas. On Oct. 12, the IceBridge team met with meteorologists at the Punta Arenas airport to discuss...

Scientists and flight crew members with Operation IceBridge, NASA's airborne mission to study Earth's changing polar ice, are beginning another campaign over Antarctica. Now in its fourth year, IceBridge's return to the Antarctic comes almost a year after the discovery of a large rift in the continent's Pine Island Glacier. The first science flight of the campaign began Friday at 8 a.m. EDT when NASA's DC-8 research aircraft left Punta Arenas, Chile, for an 11-hour flight that will take it...

Antarctic Ice Facing Changes By Fast-Flowing Glaciers
2012-09-19 14:14:23

Lee Rannals for redOrbit.com — Your Universe Online A new study found that fast-flowing and narrow glaciers could trigger massive changes in the Antarctic ice sheet, inevitably adding sea-level rise and ice-sheet decay. The team tested high-resolution model simulations against reconstructions of the Antarctic ice sheet from 20,000 years ago. Writing in the journal Proceedings of the National Academy of Sciences (PNAS), they said they used a new model during their study, capable...

Antarctic Minke Whale, Balaenoptera bonaerensis
2013-06-22 16:21:07

The Antarctic minke whale (Balaenoptera bonaerensis), also known as the southern minke whale, is one of two minke whales within the Mysticeti suborder, which contains baleen and rorqual whales. It can be found in every ocean in the southern hemisphere, residing in Antarctic waters in the summer months and northern waters in the winter months, where its range overlaps that the smaller common minke whale. The Antarctic minke whale was once classified with the common minke whale as a single...

Antarctica
2013-02-18 10:15:24

Antarctica is the Earths southernmost continent; it contains the geographic South Pole. It’s situated in the Antarctic area of the Southern Hemisphere, almost completely south of the Antarctic Circle, and is bordered by the Southern Ocean. It’s the fifth-largest continent at 5.4 million sq miles. On average, it is the driest, coldest, and windiest continent as well as having the highest average elevation of all the continents. Considered a desert, the annual precipitation is only 8...

Weddell Seal, Leptonychotes weddellii
2012-06-27 21:35:24

The Weddell seal (Leptonychotes weddellii) is a large true seal in the Lobodontini tribe. It is native to Antarctica, with its range consisting of a large “ring” that surrounds Antarctica. This seal will spend most of its time in the water instead of on land. The Weddell seal appears on the IUCN Red List with a conservation status of “Least Concern”.  It is estimated this seal numbers over 800,000 individuals in the wild. First discovered in 1820s by a British sealing captain...

Crabeater Seal, Lobodon carcinophagus
2012-06-26 14:40:11

The crabeater seal (Lobodon carcinophagus) is a true seal that can be found around the whole of Antarctica. Its range also includes small areas in South America, New Zealand, Africa, and Australia. It resides on the pack ice zone for the entire year, even as it shifts seasonally, and prefers to stay in the continental shelf area in water with a depth of less than 1,968 feet. Because the populations are so wide spread and are sufficiently mixed, there have been no subspecies found. Because...
