The crew of Coast Guard Cutter Polar Star, the United States’ only operational heavy icebreaker, is scheduled to return to Seattle after a 101-day Antarctic deployment Tuesday. Polar Star’s crew departed Seattle for Operation Deep Freeze 2015, the military resupply and logistical support mission for the U.S. Antarctic Program’s McMurdo Station. Coast Guardsmen aboard Polar Star escorted the cargo vessel Ocean Giant and fuel tanker Maersk Peary to McMurdo Station through ice ranging in thickness from 5 to 10 feet. These logistics allow scientific research to continue in the Antarctic.

Sea ice extent in both the northern and southern hemisphere was at record low levels for the month of January 2017. Last month set a record for the lowest sea-ice extent for the month, falling below the record set last year, according to the National Snow and Ice Data Center (NSIDC), a Colorado-based research outfit. Arctic sea ice this January averaged 5.17 million square miles, the lowest for the month in the 38-year sea ice record. "Greenhouse gases emitted through human activities…

West Antarctic Ice Sheet: How Stable is it?

A future warming of the Southern Ocean caused by rising greenhouse gas concentrations in the atmosphere may severely disrupt the stability of the West Antarctic Ice Sheet. The result would be a rise in the global sea level by several metres. A collapse of the West Antarctic Ice Sheet may have occurred during the last interglacial period 125,000 years ago, a period when the polar surface temperature was around two degrees Celsius higher than today. This is the result of a series of model simulations which the researchers of the Alfred Wegener Institute…

Marking the commencement of construction of the Damen Antarctic Supply Research Vessel (ASRV), a steel cutting ceremony has been held at Damen Shipyards Galati, Romania. Damen is constructing the ASRV for Serco Defence, a wholly owned subsidiary of Serco Australia who, in turn, signed a contract with the Australian Government last year for the delivery, operation and maintenance of the vessel. “Cutting the first steel for any vessel is always significant. However, the fact that the ASRV is such a ground-breaker makes this a very exciting moment,” said Damen Project Director Joop Noordijk.

As the 2015 Antarctic Treaty Consultative Meeting (ATCM) opens today in the Bulgarian capital, the Antarctic and Southern Ocean Coalition (ASOC) urged the ATCM to take action to promote the crucial importance of climate-related Antarctic research and its role in the Earth’s interconnected climate systems to the climate change community, including the United Nations Framework Convention on Climate Change (UNFCCC), in the run up this year’s COP21 climate summit in Paris. ASOC is also calling on the ATCM…

Antarctic season ends in the homeport after half a year Bremerhaven / Germany, 11 May 2016. on Wednesday, 11 May 2016, the research vessel Polarstern is expected back in its home port of Bremerhaven after a good six months of Antarctic expeditions. In the austral summer, the research vessel of the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI), penetrated into the southern Weddell Sea as far as the Filchner-Ronne Ice Shelf, where oceanographic and biological work which the focus.

Paris Climate Summit - A Missed Opportunity

As the annual Antarctic Treaty Consultative Meeting (ATCM) closed today in the Bulgarian capital, the Antarctic and Southern Ocean Coalition (ASOC) called the meeting’s adoption of a resolution on climate change a “missed opportunity” to have a meaningful impact in the run up to COP21 climate summit in Paris. The ATCM, the governing organization for the world’s seventh continent, agreed to a resolution encouraging national Antarctic scientific programmes to work with the international scientific community on the best ways to promote Antarctic climate change research in support COP21 objectives and to support national Antarctic programmes to carry out ambitious science to improve understanding of climate change impacts on the Antarctic environment and ecosystems.

Chilean Navy Aids Rescue Efforts

The Chilean Navy participated in a successful international operation rescuing a cruise liner's 100 passengers and 54 crew members after the boat crashed against an iceberg in the Antarctic Ocean. The 2,400-ton cruise liner M/S Explorer hit an iceberg early Friday near King George island in the Antarctic Ocean near a Chilean base and the Shetland del Sur islands. The cruise liner's captain and an official were the only one people to remain aboard until Friday morning, while the rest of the people remained all night in rafts floating in the cold waters. An emergency operation was carried out as soon as the accident occurred with the participation of military troops from Chile, Argentina, the United Kingdom and the United States.

Australian Antarctic icebreaker Aurora Australis has departed Casey research station to return to Australia. The ship weighed anchor to leave Casey at 1,600 hours (AEDST) carrying summer personnel, scientists and cargo for return to Australia. The 52 passengers rescued from the Akademik Shokalskiy, who have been well-cared for on board during resupply, are looking forward to the trip home. The journey to Hobart will take approximately seven to eight days and Aurora Australis is expected to arrive in Hobart on or about January 22, about 14 days later than originally scheduled.

The Antarctic Ocean Alliance (AOA) called on the 25 member countries gathering today for the annual meeting of the Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR) to finally agree on lasting and significant Southern Ocean protection. CCAMLR previously pledged to establish two marine protected areas by 2012, but, because of a lack of consensus, member states have failed to reach agreement on two major proposals on four separate occasions. The Southern Ocean is home to more than 10…

Research ship 'Akademik Tryoshnikov' built by Admiralty Shipyards will be employed in the service of Russian Antarctic stations. The Akademik Tryoshnikov is the first research vessel in the last 20 years built by the Admiralty Shipyards to order by Roshydromet. It will be used to resume annual maintenance of the Bellingshausen Station in the Russian Antarctic, and to reopen the Russkaya Station, which was closed in 1989. This station is the only location in the world where researchers can monitor various natural processes occurring across the space of several thousand kilometers.

Loss of Diversity Near Melting Coastal Glaciers

Dallmann-Expedition 2015

Melting glaciers are causing a loss of species diversity among benthos in the coastal waters off the Antarctic Peninsula, impacting an entire seafloor ecosystem. This has been verified in the course of repeated research dives, the results of which were recently published by experts from Argentina, Germany and Great Britain and the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI) in a study in the journal Science Advances. The scientists believe increased levels of suspended sediment in the water to be the cause of the dwindling biodiversity in the coastal region.
