Australia Stops Sea Shepherd From Using Drones
2012-01-03 13:51:55

The Australian government has stopped the anti-whaling group Sea Shepherd from using unmanned drones over the Antarctic. The Australian Antarctic Division told the group the drones must have an urgent environmental impact assessment if they are to be used in Antarctic Treaty waters. The drones were used by the group in December to find the factory ship Nisshin Maru before it made it into Antarctic waters. The Australian government requires anyone going to the far south from an...

Climate change effects to be monitored with new fiber-optic distributed temperature sensing Half-mile long thermometers have been dropped through the Ross Ice Shelf in Antarctica that will give the world relevant data on sea and ice temperatures for tracking climate change and its effect on the glacial ice surrounding the continent. The study based at the University of Nevada, Reno is funded by the National Science Foundation's Office of Polar Programs and other NSF grants. "This...

First record of a sauropod dinosaur in Antarctica suggests more widespread distribution of this species than previously thought For the first time, the presence of large bodied herbivorous dinosaurs in Antarctica has been recorded. Until now, remains of sauropoda - one of the most diverse and geographically widespread species of herbivorous dinosaurs - had been recovered from all continental landmasses, except Antarctica. Dr. Ignacio Alejandro Cerda, from CONICET in Argentina, and his...

100th Anniversary Of First South Pole Expedition

Explorers, scientists, and the prime minister of Norway were among those who gathered at the South Pole Wednesday to commemorate the 100th anniversary of the date that Norwegian explorer Roald Amundsen became the first man to ever lead a successful expedition to the Antarctic site. "We are here to celebrate one of the greatest feats in human history," Prime Minister Jens Stoltenberg said while unveiling an ice sculpture of Amundsen, according to Nils Myklebost of the Associated Press (AP)....

Next week marks 100 years since Roald Amundsen reached the South Pole. As a team of scientists brave the Antarctic to validate data from ESA´s CryoSat mission, it´s hard to imagine what these first intrepid explorers would have thought of today´s advances in polar science. The remote and vast expanse of the Antarctic is arguably the most hostile environment on Earth — infamously claiming the lives of Captain Robert Scott and his party all those years ago in their fated...

Accelerated melting of two fast-moving outlet glaciers that drain Antarctic ice into the Amundsen Sea Embayment is likely the result, in part, of an increase in sea-surface temperatures in the tropical Pacific Ocean, according to new University of Washington research. Higher-than-normal sea-level pressure north of the Amundsen Sea sets up westerly winds that push surface water away from the glaciers and allow warmer deep water to rise to the surface under the edges of the glaciers, said...

Scientists have created a detailed map called BEDMAP of Antarctica's rock bed that lies underneath its icy surface. The map gives a view of the landscape beneath the ice, and incorporates decades of survey data acquired by planes, satellites, ships and even people on dogsleds. In the map, the highest elevations are marked in red/black, while the light blue color shows the extent of the continental shelf.  The lowest elevations are dark blue, some of which lie below today's seal...

In order to identify the flight routes of the birds, postgraduate Matthias Kopp, under the guidance of Dr. Peter, equipped South Polar skuas with geolocators in their breeding areas on King George Island, about 120 kilometers off the Antarctic Mainland. Thus he has been screening their position data over a period of several years, followed by an analysis together with British colleagues and a scientist from Switzerland. "With the help of these data we can now for the first time...

A remarkable ESA campaign in one of the remotest regions on Earth has been fundamental in ensuring that the SMOS mission is delivering reliable data to improve our understanding of Earth´s water cycle. The two-year campaign set out to answer a simple but important question: do the microwave signals of a particular wavelength emitted from the surface the Antarctic ice shelf towards the SMOS satellite change over time? For a satellite mission that maps variations in soil...

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...

Ross Seal, Ommatophoca rossii
2013-01-01 15:44:30

The Ross seal (Ommatophoca rossii) is a true seal in the Phocidae family, and can only be found on pack ice in Antarctica. This species was formally described by James Clark Ross in 1841, during his British Antarctic Expedition. It is very uncommon to see in its range and rarely leaves the pack ice, with stray individuals occurring off southeast Australia or sub-Antarctic islands. The Ross seal can reach an average length between 5.5 and 6.9 feet, although some females can reach up to 8.2...

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...

Antarctic Silverfish, Pleuragramma antarcticum
2012-04-02 17:14:35

The Antarctic Silverfish, (Pleuragramma antarcticum), is a member of the Notothenioidei family of fish. It is widely distributed around the Antarctic, but has largely disappeared from the western side of the northern Antarctic Peninsula based on 2010 research funded by the National Science Foundation. It is also found throughout the Southern Ocean. It grows to an average size of 6 inches, but has been known to reach lengths of up to 10 inches. It is usually pink with a silver tint, and...

Cryolophosaurus, meaning "cold crest lizard", is a genus of theropod dinosaur from the Early Jurassic Period (Pliensbachian Age). It is known from the Hanson Formation (previously known as the Upper Falla Formation). It was discovered by paleontologist Dr. William Hammer in 1991. It was the first carnivorous dinosaur to be discovered in Antarctica. It was also the first dinosaur from Antarctica to be officially named. Dr. William Hammer and his team unearthed the dinosaur during the...

  • The unit of magnetic flux density in the International System of Units, equal to the magnitude of the magnetic field vector necessary to produce a force of one newton on a charge of one coulomb moving perpendicular to the direction of the magnetic field vector with a velocity of one meter per second. It is equivalent to one weber per square meter.
This word is named for Nikola Tesla, the inventor, engineer, and futurist.
