Who we are and what we're doing!


Welcome to our project site!
We are six National Science Foundation-funded researchers from Pacific Lutheran University, Berkeley Geochronology Center, University of Washington, and the University of Maine who are studying the glacial history of the Pensacola Mountains in West Antarctica.

Our 2011-2012 field season is almost underway! We will spend about two weeks in McMurdo equipping ourselves for another month in the Pensacola Mountains. We spent December 16th, 2010 through January 17th, 2011 in the Pensacola Mountains, where we mapped and sampled glacial deposits along the Foundation Ice Stream. This year, we will revisit last year's field sites, and map new regions of the mountain range.

Our work will track the thinning history of the Weddell Sea Sector of the West Antarctic Ice Sheet, and will also provide insights into ice sheet dynamics, and the history of sea level contribution from this sector of the ice sheet.

In the coming weeks and months, we will use this site to show you our preparations for the 2011-2012 field season, and to share our initial results as they emerge. Please check back to catch up with our progress. Thanks for finding us!

December 19th - Our first day in the Schmidt Hills!

Hello Friends!

The map below gives you a rough idea of our route to our Schmidt Hills camp, which was documented in the pictures in my last post.


Our adventure continued in the Schmidt Hills! We spent the morning of our first full day in the Schmidt Hills organizing our camp. After that, we hiked up to the nearest mountain to begin to orient ourselves to the area.

Heading out of camp for our first hike in the Schmidt Hills



You can barely see our camp in the distance! For those of you who are following a map, this photograph was taken facing east across the valley in the middle of the Schmidt Hills. 
Greg and Chris summiting the peak to the ESE of camp, just north of Mount Coulter on the map above.
Group shot! We are wearing harnesses because we had to rope up to cross the snow and ice immediately below the edge of the exposed rock.
Seth admiring the view out to the shear margin of the Foundation Ice Stream. The force that the fast-flowing ice of the ice stream places against slower surrounding ice stresses the ice at the margin. The ice cracks in response to this stress, causing a band of crevasses. In this photograph, the shaded, rough-looking area you see beyond the rock is the eastern shear zone of the Foundation Ice Stream.
Tomorrow, I'll post two more entries. The first one will show you how we flag safe travel routes in our field areas, and the second will summarize our rock sampling efforts in the Schmidt Hills! Many more beautiful pictures to come.

I'm also working on creating a maps page where you can see higher-resolution satellite imagery of our field area.

Stay tuned! Hope all is well,

Claire
