Press release Exploration of lake hidden beneath Antarctica's ice sheet begins 15 January 2008 PR No. 1/2008 A four-man science team led by British Antarctic Survey's (BAS) Dr Andy Smith has begun exploring an ancient lake hidden deep beneath Antarctica's ice sheet. The lake - the size of Lake Windermere (UK) - could yield vital clues to life on Earth, climate change and future sea-level rise. Glaciologist Dr Smith and his colleagues from the Universities of Edinburgh and Northumbria are camped out at one of the most remote places on Earth conducting a series of experiments on the ice. He says, "This is the first phase of what we think is an incredibly exciting project. We know the lake is 3.2km beneath the ice; l...

We had a slight “event” a week or so ago, when our group was at a site called Mt. Paterson. Mount Paterson is about 550 miles west of McMurdo, somewhat near the coast. I would have put a post up about this earlier, but it was a somewhat sensitive issue. Enough time has elapsed now, and I think it is important to talk about, so I’m putting up some photos. In short, we had a plane crash in the Basler. If you have read previous posts, you will know that a Basler is a fixed wing aircraft, slightly larger than a Twin Otter, and therefore capable of carrying more weight. It uses skis to land, just like a Twin Otter. I wasn’t on the flight, another member of our group, Bob, ended up taking my place. There were six people from out group total (3 GPS, 3 seismic) and 4 people from fixed wing...

There's a changed mood on board now the frantic pace of the CTD (Conductivity, Temperature, Depth) circuit has abated. Work continues along with the CEAMARC trawls but it seems as if people have been absorbed by the ship. I have a kind of holiday - a reading blitz, and have just finished reading about the explorer Hubert Wilkins. Wilkins grew up on a property on the wrong side of the Goyder line in South Australia and saw the Federation drought of 1901 destroy the family farm. His remarkable exploration expeditions to both poles were driven by a certainty that understanding the climate of the polar regions was the key to predicting weather and that understanding climate could alleviate human suffering. When he set off for Antarctica with Shack...

Press Release from RV Polarstern 04.01.2008 Antarctic biodiversity research hits Time magazine’s “Top 10” scientific discoveries for 2007 Time Magazine has recognised Antarctic biodiversity research in its Top 10 scientific discoveries for 2007. The discovery was reported in the journal Nature in May 2007. The researchers found over 700 new species of organisms, including isopod crustaceans, carnivorous sponges and giant sea spiders on the seafloor of the Weddell Sea off Antarctica, at bottom depths from 700 m to 6,000 m. The Nature paper on biodiversity and biogeography of the Southern Ocean deep sea was published by a team of 21 biologists. Right now, four of them are at sea off Antarctica on the German icebreaker RV Polarstern, conti...

The IPY exhibit at the Exhibition on Earth observations during the Ministerial Summit of the Group on Earth Observations (GEO) 27-30 Nov 2007 in Cape Town, South Africa was well attended by ministers and visitors. Dr Pierre Cilliers from the Hermanus Magnetic Observatory and Mr Michael Nxumalo, professional officer of the Souith African IPY office at the National Research Foundation set up and attended to the stand on behalf of the International IPY office. The stand also featured several posters on topics related to the South African IPY programme. The themes of the posters were among others "The Hermanus Magnetic Observatory, Contributions to Global Observations of the Earth's Geomagnetic Field", "The Hermanus Magnetic Observatory, Space Weather Observation for disast...

The October 2007 issue of the WMO Bulletin focussed on the International Polar Year 2007-2008. The issue contained an IPY overview and six articles covering polar weather, stratospheric ozone, polar atmospheric chemistry, polar oceans, cryosphere connections to hydrological cycles in the Arctic, and future space observations of polar regions. As part of its sponsorship of IPY, WMO makes the IPY articles (in English) available for free download on its website, see: http://www.wmo.ch/pages/publications/bulletin/october_2007.html These articles provide fresh reviews of many aspects of polar science. The I...

Watch the glaciers of Kenai Fjords transform before your eyes as nearly a century of change is revealed by repeat photography. Dr. Bruce Molnia, glaciologist with the U.S. Geological Survey, has been conducting repeat photography research throughout Alaska for the last decade. His work in Kenai Fjords National Park focuses on photographs shot in 1909 by U.S. Grant and D.F. Higgins. Between 1905 and 1909, they completed the first detailed survey of the glaciers of Prince William Sound and the Kenai Fjords coast. Their photographs, archived in Denver, Colorado, provide an opportunity to document a century of change. With support from the Park Service motor vessel Serac, Molnia traveled the Kenai Fjords coast, duplicating the 1909 photos. Using clues such as mountain ridge lin...

The Shamrock Glacier in Lake Clark National Park and Preserve, Alaska, USA, has receded about 2 miles from its 1928 position near its terminal moraine. Some newly exposed morainal surfaces are now vegetated. 1928 photograph by Stephen R. Capps. 2004 repeat photography by M. Torre Jorgenson. The Southwest Alaska Inventory & Monitoring Network (SWAN) is an office of the National Park Service dedicated to providing the scientific foundation for effective, long-term protection and management of natural resources in five units of the national park system. Collectively these units comprise approximately 9.4 million acres, 11.6 percent of the land managed by the National Park Service, or 2 percent of the Alaska landmass, and include a diversity of geologic features, eco...

Climate Change ‘Magic’: Disappearing Lakes and Reappearing Artifacts In the summer of 1999, artist Hamish Fulton took a hike through the icefields of Wrangell-St. Elias National Park and Preserve (WRST). One highlight of his journey was a traverse near Iceberg Lake on the Bagley Icefield. Imagine his surprise when he crested a low pass expecting to see the lake, but all that remained was a small creek emerging from the melting terminus of a small alpine glacier. Icerberg Lake had disappeared. While in another area of WRST, scientists were discovering rare archeological materials melting from ancient glaciers. How and why these events happened is covered in the latest issue of Alaska Park Science. The tenth issue of Alaska Park Science, entitled “S...
