Scientists have discovered an active methane seep from Antarctica's sea bed that could shed light on the potent greenhouse gas trapped beneath frozen continent. Marine ecologist Andrew Thurber first glimpsed what a colleague described as a “microbial waterfall” during a dive in the icy waters of the Ross Sea in 2012.
Two new research projects – in partnership with British Antarctic Survey engineers – will drill deeper than ever before in Antarctica and in space. The first project, called INCISED, is led by the University of Durham, funded by the European Research Council, and has set its sights on the Antarctic. It will drill bedrock from beneath the polar ice sheets, with the goal being to retrieve scientific samples.
Mussels are the first-ever invasive species to take up residence in Antarctica, as found by a new study published last month in Scientific Report. According to the study, scientists found a colony of mussels, most likely transported accidentally to the frozen continent from Patagonia via ship, some 75 miles north of the Antarctic Peninsula.
Antarctica is now a harsh land of ice and snow but has not always been that way. Earth's southernmost continent long ago was home to temperate, swampy rainforests teeming with life, scientists said on Wednesday based on pristinely preserved forest soil they retrieved by drilling under the seafloor off Antarctica's coast.
The International Association of Antarctica Tour Operators (IAATO) announced on Thursday the appointment of Gina Greer as Executive Director. Gina will lead the Secretariat and work with IAATO’s Executive Committee to further the association’s mission of advocating and promoting safe, environmentally responsible private-sector travel to Antarctica.
Argentine researchers have announced the discovery of fossilized skin on the remains of the wing of a 43-million-year-old penguin on Marambio Island in the Antarctic.
Cruise vessel Roald Amundsen has been involved in a history-making event as it has travelled the furthest south of any Hurtigruten company ship in the expedition cruise line's 127 years of business, the company said, in a statement.
BAM Nuttall Ltd, which has been selected by the Falkland Islands Government, FIG, as the development partner to design and build a new port in Stanley Harbour is no adventurer in the South Atlantic and is closely linked to the UK efforts and investments in Antarctica. In effect, BAM Nuttall is involved in the building of the British Antarctic Survey's largest facility at Rothera Research station.
Scientists in Antarctica have recorded a new record temperature of 20.75 degrees Celsius, breaking the barrier of 20 degrees for the first time on the continent, a researcher said on Thursday.
Scientists in Antarctica have recorded, for the first time, unusually warm water beneath a glacier the size of Florida that is already melting and contributing to a rise in sea levels. The researchers, working on the Thwaites Glacier, recorded water temperatures at the base of the ice of more than 2 deg C, above the normal freezing point.
