Polenet Starts to Install GPS Systems at Brimstone Peak, Antarctica
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...

Norway-US Traverse: 2nd deep drill hole is well underway
Written 19 Dec 2007
3619 meters above sea level
Maximum & Minimum temperatures: -25 to -35°C
No doubt, this ice core has really challenged us. We started drilling last Saturday and have encountered a series of problems since then. Today, however, it seems like we reached a turning point. The optimism is back in the hard-working drilling team and maybe by tomorrow the second 90 meter ice core is retrieved.
Today, we also took part (by satellite phone) in a press seminar in connection with the visit of Norwegian Prime Minister Jens Stoltenberg to Troll Station in January 2008.

WMO Bulletin highlights IPY
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...

Exploring the Emperor Cone lava
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.

Norway-US Traverse: Test flight of the UAV
Written 18 December, 2007
3619 meters above sea level
Maximum & Minimum temperatures: -22 to -32 °C
All cameras were pointed towards the unmanned aerial vehicle (UAV) launcher when Stian made his first test flight today. The UAV carries one C-band radar, temperature and pressure sensors, a digital camera and a GPS. The C-band radar is similar to the ones on satellites and to the one we have mounted on one of the vehicles. Thus, data from these three different platforms will be compared. The camera can be used for route planning and crevasse detection. Some modifications will be made before the first long ...

Research vessel Polarstern sets out for Antarctic research season
PRESS RELEASE Climate change and life in the Southern Ocean Research vessel Polarstern sets out for Antarctic research season Bremerhaven, November 27, 2007. A ten-week expedition to the Lazarev Sea and the eastern part of the Weddell Sea opens this years Antarctic research season of the German research vessel Polarstern. On the evening of November 28, just some two hours after an official ceremony at the Berlin Museum of Natural History honouring Polarsterns 25th anniversary of service, the research vessel will begin its 24th scientific voyage to the Southern Ocean from Cape Town. The 53 scientists from eight nations aboard Polarstern will focus much of their work on climate-related research as part of the International Polar Year. In additio...

Norway-US Antarctic Traverse: Visited by a Basler aircraft
Written 17 Dec 2007
3619 meters above sea level
Maximum & Minimum temperatures: -22 to -36°C
The medical doctor at Troll paid us a visit today to inspect the wounded finger of our chief driller. In addition, we were supplied with spare parts for the vehicles.
The doctor inspected the wounded finger and put the chief driller on medication to prevent further inflammation. She is doing fine but is not allowed to use her right hand in order for the wound to heal. The remaining part of the drill team has currently reached to a depth of 50 meters.
The Basler also carried spare parts for our vehicles, in particular two transfer boxes, one differential and hydraulic oil. Shallow coring was completed and Stian prepared for flying the dron...

Studying Sun Shadows Around the World
Two eighth-grade students at James Monroe Middle School in Albuquerque, New Mexico are collaborating with staff at several Antarctic stations including; the Amundsen-Scott South Pole and Palmer Stations to measure shadows. By comparing the length of shadow the sun casts from a one-meter stick at solar noon measured at locations experiencing either winter or austral summer these students are testing the "longer shadows in the winter and shorter shadows in the summer" understanding.
Students have also arranged for several snapshot winter readings to be taken across the continental United States on solstice. Measurements h...

Arriving on the Ice: POLENET begins its ambitious field season
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...

Norway-US Antarctic Traverse: Chief driller has a wounded finger
Written 16 Dec 2007
3619 meters above sea level
Maximum & Minimum temperatures: -20 to -36 °C
Our chief driller has been troubled with a bleeding finger the last week due to metal pieces that are stuck in the finger. The situation has become worse these last few days and she is currently requested by our paramedic Kjetil to quit working.
The wound has been bleeding this last week. It is not serious but the wound will not heal properly. Today, our medical responsible, Kjetil Bakkland, removed pieces of metal in the finger but there might be more remaining. Because of this, the drilling of t...
