One of the biggest icebergs on record has broken away from Antarctica, scientists said on Wednesday, creating an extra hazard for ships around the continent as it breaks up. The one trillion tonne iceberg, measuring 5,800 square km, calved away from the Larsen C Ice Shelf in Antarctica sometime between July 10 and 12, said scientists at the University of Swansea and the British Antarctic Survey. The iceberg, which is roughly the size of the U.S. state of Delaware or the Indonesian island of Bali, has been close to breaking off for a few months.

The 29 countries party to the Antarctic Treaty unanimously agreed today to a resolution at the 39th Antarctic Treaty Consultative Meeting (ATCM) stating their “firm commitment to retain and continue to implement…as a matter of highest priority” the ban on mining activities in the Antarctic, which is part of the Protocol on Environmental Protection to the Antarctic Treaty (also called the Madrid Protocol). The resolution was initiated by the United States to commemorate the 25th anniversary of the 1991 signing of the Protocol.

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.

The Australian Antarctic Division has rescheduled its early season voyages with the icebreaker Aurora Australis delayed in heavy ice conditions off the Antarctic coast. The ship is in heavy ice about 180 nautical miles off Davis station, returning from resupplying the station and delivering summer personnel. Radar satellite images this morning indicated that while there may be some useful openings, the sea ice extends to approximately 60 nautical miles around the ship. Beyond that, less concentrated ice will be easier to navigate. Australian Antarctic Division Director, Dr.

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…

Antarctic Cruise Hits Rocks

The MS Nordkapp hit rocks near Deception Island, an ice-capped caldera off the Antarctic peninsula that is a popular stop for cruise ships. It sustained an 80-ft. gash in her bows. As the ship dropped anchor, the Royal Navy ice-patrol ship HMS Endurance responded to a call for assistance, dispatching a helicopter and diving teams to assess damage and supervising the transfer of passengers to the Nordkapp’s sister ship, MS Nordnorge. Speaking from the bridge of HMS Endurance, Captain Nick Lambert said that once passenger safety had been secured, his priority was to contain pollution. While nobody was hurt, the accident highlights the vulnerability of unspecialized ships sailing in remote and often uncharted Antarctic waters.
