22 December 2007 Westhaven Nunatak, Antarctica. The goal of this field season is to deploy GPS systems on bedrock, so we can understand how the bedrock is moving. These systems are meant to be “permanent”, in that they will operate year round. We get to these sites by helicopter, and a twin otter (a type of fixed wing aircraft). When we are within 200 km of McMurdo, the U.S. base station, we use helicopter support to reach our sites. Unfortunately, weather has been bad this year. A lot of low pressure systems, which means low-hanging clouds, which means no helicopter work. We had an opportunity last week where weather was good, so we took advantage of it and flew both during the day and the night (it’s light here 24 hours a day in the summer). We ...

The site progettosmilla.it has an aim of explaining to the Italian students (with a target of 14 years old) and teachers, the ANDRILL project and the basic geographic features of Antarctica. In the various sections of the site, users can find detailed descriptions (made by a teacher of the educational project of ANDRILL with the supervision from ANDRILL scientists) of all the phases of the research viz. objectives, methods, instruments and results. The idea is to involve as many as possible students and teachers in the scientific process and adventure of the ANDRILL research. In order to support this, the site further contains: multimedia material (1450 photos, 20 videos and 10 audio), blogs, interactive a...

We were all pretty exhausted after 12 hours in the field, but wanted to take advantage of the weather, so back out we went 45 minutes later, this time to a site called Brimstone Peak. The site install went well (although we will need to go back to finish up one more item) and the weather was great again. Again, about -20C (-4F) and not too much wind. Really ideal conditions for an altitude of 7,500 ft. but still tiring to move all that equipment…. Guick lesson for those who don’t know: The way oxygen works at altitude is that as you get higher, the pressure decreases. Basically this means that your body has to work harder to pump oxygen from your lungs into your blood. That’s why it’s harder to breathe when you are at high elevations. So here’s the catch: the bar...

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...

Summer seems to have arrived on Mt. Morning. The air outside my tent today was cool, and if it wasn’t entirely springlike, temperatures were certainly above freezing. Margins of a few icy ponds had melted, and little sprigs of algae unfurled green fronds under the surface. We spent the day traversing the 25,000-year-old lava flows below Emperor Cone. Traveling with geologists, you don’t have to worry too much about forgetting your water bottle – our camp was almost always in sight. In about nine hours, we got no farther away from camp than 1 kilometer. But in that short space we found plenty to look at: wind-eaten rocks, two very different forms of lava, and a fence of hexagonal stone pillars, among other sights you’ll hear about another day.

My name is Stephanie, and I am a graduate student with Ohio State University. My research focuses on using GPS to study crustal deformation in Antarctica, and this blog is meant to document my experiences in Antarctica, or “the ice” as it is affectionately known by many. This is my third time down to the ice, but only my second season. By season, I mean summer in Antarctica, from about October through February, when the sun is out for 24 hours a day. In 2004/2005, I was here putting out GPS equipment throughout the Transantarctic Mountains as part of the TAMDEF project (Transantarctic Mountain Deformation Project). Now I am here continuing that work as part of a project called POLENET (Polar Earth Ob...

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...
