Sarah-Louise Simmons, 22 years old and a PhD student at the University of Bristol. I’m a glaciologist studying the effect of carbon runoff from Greenland on the Arctic Ocean. Here I am looking very cool on a glacier in Svalbard! Read more on my Svalbard adventure here: http://la-mooey.blogspot.co.uk/2012/08/svalbard-74-to-81-north.html

I am a geologist and a glaciologist.  I have a Masters Degree in Geology from the University of Washington.  I have traveled to Antarctica to study the motion of the West Antarctic ice sheet near a flow divide, and I have cored lakes in Montana to try and understand the timing of the last ice age.  Currently I work with large mineral deposits all over the United States.  In this picture I am studying the glaciers of Mt. Rainier in the state of Washington.  This is what a scientist looks like.

My name is Erin Pettit, I am a glaciologist at the University of Alaska Fairbanks. I study glaciers and ice sheets and their role in our changing climate - in Antarctica, Greenland, Alaska, Canada, and more. I also explore the mountains with a team of teenage girls each summer through my program called Girls on Ice.
