A huge number, 150,000, of Adélie penguins have disappeared from Antarctica's Commonwealth Bay. A recent study tied the occurrence to a giant iceberg that grounded in the area, isolating the penguins and causing them to starve to death. But critics are challenging that claim, suggesting that the birds relocated, instead.
When a giant iceberg crashed down in Commonwealth Bay, Antarctica, in 2010 it isolated a colony of Adélie penguins. Having to trek much farther for food, 150,000 penguins have died, putting the colony at risk of extinction.
In the dark, cold waters of both the Antarctic and Arctic oceans, sea spiders are growing larger than usual. Researchers say this phenomenon, known as polar gigantism, may or may not be attributed to the abundance of oxygen in the seawater.
Gentoo penguins, an arctic species distributed around the South Pole, have evolved a special method to remian ice-free, say researchers who are now hoping to adapt their findings to airplane wings which frequently need de-icing. "It's a little ironic that a bird that doesn't fly could one day help airplanes fly more safely," said one researcher.
Using a new, specialized net, a team of researchers recently collected polar cod (Boreogadus saida) from their icy homes in order to better understand the fishes' large-scale distribution and origin as well as the predators that feed on them.
Recently, researchers have pointed out that Antarctica's melting hasn't been as intense as many climate change experts had feared. However, new research has revealed that this is all about to change, with new data hinting that the White Continent's surface will double its current melt rate by 2050.
Climate change could warm ocean water temperatures to the point where king crabs could migrate to shallower Antarctica waters, drastically altering marine fauna along the continental shelf and causing widespread reduction in biodiversity.
University of Alaska Fairbanks researchers recently developed a computer program that estimates the impact climate change could have on the Antarctic ice sheet.
Researchers have been surveying bottom-dwellers in Antarctica for over two decades. After comparing high-resolution images, they found that an increasing amount of marine organisms are produced annually and they are storing surprisingly high amounts of carbon.
While the Southern Ocean was thought to have a weakening role in carbon uptake from the early 1990s to the early 2000s, that has changed, according to a new study.
As part of their ongoing "ScienceCasts" video series, Science@NASA reminds just how closely experts from around the world have been keeping a wary eye on Greenland's ice sheet. The result has been a mountain of research all showing the same thing: under the thinning of ice is a whole lot of nothing, and that's not good news.
Penguin fossils found in Antarctica reveal valuable information about the bird's unique adaptations. While they have evolved as flightless birds, they have many interesting traits that allow them to fly through water.
Iron stored in glaciers is running off into certain Antarctic coast marine areas, feeding phytoplankton and thus the rest of the marine food chain.
For a fish that takes up to 10 months to develop, researchers have new findings on how this Antarctic creature would fare in warmer water and elevated carbon.
