February 21, 2011 (PhysOrg) – The contribution of Greenland to global sea level change and the mapping of previously unknown basins and mountains beneath the Antarctic Ice Sheet are highlighted in a new film released by Cambridge University this morning. The work of glaciologist Professor Julian Dowdeswell, Director of Cambridge University’s Scott Polar Research Institute, […]
By MICHAEL FIELD26 February 2011 (Stuff) – An Antarctic ice shelf used as a runway is breaking away, forcing an emergency airlift to close summer operations on the continent. The situation is being complicated by the Christchurch quake which is limiting operations at Christchurch Airport. Staff at New Zealand’s Scott Base and the US’s McMurdo […]
A warmer Antarctica makes a hospitable home for these crabs, endangering an entire ecosystem that has no defenses against them. By Eric NiilerTue Feb 8, 2011 07:00 AM ET McMURDO STATION, Antarctica — Warming waters along the Antarctic peninsula have opened the door to shell-crushing king crabs that threaten a unique ecosystem on the seafloor, […]
Caption by Kathryn Hansen and Michael CarlowiczJanuary 19, 2011 In October 2009, a series of flights over Antarctica led to the discovery of a hidden feature beneath a floating ice shelf. Scientists participating in NASA’s Operation IceBridge mapped the water depth and seafloor topography beneath Pine Island Glacier and found a deepwater channel—a likely pathway […]
New paper in Nature Geoscience examines inertia of carbon dioxide emissions Contact: Jennifer Myers, myers@ucalgary.ca, University of Calgary 9-Jan-2011 New research indicates the impact of rising CO2 levels in the Earth’s atmosphere will cause unstoppable effects to the climate for at least the next 1000 years, causing researchers to estimate a collapse of the West […]
By David DeFranza, Washington, DCon January 6, 2011 Between 2005 and 2006, author Fen Montaigne traveled to Antarctica with Fraser to observe the life cycle of the penguins. “This colony was once much larger,” Montaigne says, “but in recent years all the Adélie colonies in the northwestern Antarctic Peninsula have been in steep decline as […]
By Lee-Maree GalloOctober 25, 2010 – 11:36AM Increased snowfall in the Antarctic has been linked to drought in south-western Australia. Researchers, including Australian Antarctic Division principal research scientist Tas van Ommen, have been analysing ice cores in the Antarctic and revealed snowfall variability may be linked to climate in the Southern Ocean and the South-West. […]
By News StaffSeptember 6th 2010 01:00 AM The Greenland and West Antarctic ice caps are melting at half the speed previously predicted, shows a team from the Jet Propulsion Laboratory, Delft University of Technology (TU Delft, The Netherlands) and SRON Netherlands Institute for Space Research in Nature Geoscience. The melting of the ice caps has […]
By Alister Doyle, ReutersWednesday, 1 September 2010 Tiny marine creatures found on the seabed on opposite sides of West Antarctic give a strong hint of the effects of sea level rise, say scientists. The discovery of very similar colonies of bryozoans, animals that anchor themselves to the seabed, in both the Ross and Weddell Seas […]
By Rodrigo OrihuelaAug 3, 2010 7:45 AM PDT Argentina is importing record amounts of energy as the coldest winter in 40 years drives up demand and causes natural-gas shortages, prompting Dow Chemical Co. and steelmaker Siderar SAIC to scale back production. Electricity supplied from Brazil and Paraguay rose to a daily combined record of about […]
