Measuring a Glacier’s Motion

WHILLANS ICE STREAM, ANTARCTICA-- There are two basic projects that we are working on through our field work in Antarctica. One is looking at changes in the ice surface motion through time. To do this we make three types of GPS measurement... {Read More »}

Returning Home

LARAMIE, WYOMING-- During last week, the weather steadily turned from cold and overcast to warm and sunny. On the first day of good conditions we launched in the morning and captured a bear shortly thereafter... {Read More »}

Whillans Ice Stream behaves in a unique way – it slips twice a day in episodes that are linked to the tidal cycle... {Read More »}

Why We Install GPS Systems

DEVERALL ISLAND, ANTARCTICA-- The POLENET project installed their newest high-precision GPS system on Deverall Island, Antarctica. These GPS systems tell us how much the ground underneath the ice sheet is moving upward... {Read More »}

Life on the West Antarctic Ice Sheet

WHILLANS ICE STREAM, ANTARCTICA-- In this audio dispatch, I describe our first week in our field camp on the West Antarctic Ice Sheet. Hear about our research on lakes under the glaciers and get a slice of life as a remote polar scientist... {Read More »}

Tango 1 and the Air We Breathe

MCMURDO STATION, ANTARCTICA-- We have been preparing for a week to move to our deep field location, Tango 1. Tango 1 is a camp deep in the Transantarctic Mountains about 800 miles from the McMurdo Station. This is going to be a completely new Antarctic experience for me... {Read More »}
