Passage of icebergs through surface waters changes their physical and biological characteristicsIn a finding that has global implications for climate research, scientists have discovered that when icebergs cool and dilute the seas through which they pass for days, they also raise chlorophyll levels in the water that may in turn increase carbon dioxide absorption in the Southern Ocean.An interdisciplinary research team supported by the National Science Foundation (NSF) highlighted the research...

Icebergs apparently head off to South Georgia when they are going to die. The blocks of ice break off Antarctica and get swept towards the Atlantic and then ground on the shallow continental shelf that surrounds the 105-mile long island. They dump billions of tons of freshwater into the local marine environment. U.K. scientists say that the giants have quite dramatic impacts, even altering the food webs for South Georgia's animals. "The scale of some these icebergs is something else,"...

Adding to their unique information from previous tandem missions, ESA's ERS-2 and Envisat satellites have been paired up again "“ for the last time. Data from this final duet are generating 3D models of glaciers and low-lying coastal areas. The 2010 tandem campaign continues the work of the satellites' earlier joint efforts on measuring the speed of fast-moving glaciers, detecting land-ice motion and developing elevation models over flat terrain. Their third pairing took place from...

On Aug. 5, 2010, an enormous chunk of ice, about 251 square kilometers (97 square miles) in size, or roughly four times the size of Manhattan, broke off the Petermann Glacier along the northwestern coast of Greenland. The Petermann Glacier lost about one-quarter of its 70-kilometer-long (40-miles) floating ice shelf, according to researchers at the University of Delaware, Newark, Dela. The recently calved iceberg is the largest to form in the Arctic in 50 years. Icebergs calving off the...

A massive iceberg has broken off from a glacier in Greenland and has started drifting south into shipping lanes and waters occupied by oil rigs, according to a recent Associated Press (AP) report. On Tuesday, AP writer Karl Ritter noted that the iceberg, which detached from the Petermann glacier in Greenland last week, was "an island of ice more than four times the size of Manhattan." He also noted that the 260 square kilometer mass could cause "untold damage" as it drifts south towards the...

Envisat has been observing a rare event in the Arctic since early August - a giant iceberg breaking off the Petermann glacier in North-West Greenland. The Petermann glacier is one of the largest glaciers connecting the Greenland inland ice sheet with the Arctic Ocean. Upon reaching the sea, a number of these large outlet glaciers extend into the water with a floating 'ice tongue'. The ice tongue of the Petermann glacier was the largest in Greenland, with an extension of about 70 km until...

An award-winning new website is using realtime imagery from ESA's Envisat satellite to provide a wealth of information on sea ice to aid safe passage through the treacherous waters of the Antarctic. Although remote, the Southern Ocean is an increasingly busy route for sea traffic. These seas are used more and more to conduct scientific research, transport freight, harvest fertile fishing grounds and carry tourists to experience one of Earth's last wildernesses. However, ever-changing pack ice...

New detailed observations of what happens when glaciers float on ocean surface Glaciers that lose their footing on the seafloor and begin floating behave very erratically, according to a new study led by a Scripps Institution of Oceanography, UC San Diego researcher. Floating glaciers produce larger icebergs than their grounded cousins and do so at unpredictable intervals, according to Scripps glaciologist Fabian Walter and colleagues in a paper to be published in the journal Geophysical...

A mammoth iceberg that struck a glacier off Antarctica, dislodged a newer chunk of ice that could affect ocean currents and also lower the levels of oxygen in the world's oceans, according to Australian and French scientists. The two icebergs are drifting together about 62 to 93 miles off Antarctica after the Feb 12-13 collision, said Neal Young, a glaciologist for the Australian Antarctic Division. The first iceberg, measuring 60 miles long, collided with the Mertz Glacier Tongue and...

The giant iceberg, known as B17B, is gradually breaking up into smaller pieces as it drifts northeast from Antarctica towards Australia. The 140 square kilometer block of ice has now reduced its size to 115 square kilometers, making the iceberg approximately 18 kilometers long by 8 kilometers wide. Australian Antarctic Division glaciologist, Dr Neal Young, has been tracking the iceberg's progress using satellite images from NASA and the European Space Agency since it was first seen about...
