CReSIS: bringing you info on climate change one ice sheet at a time

Did you know that glaciers could be up to two miles thick and weigh more than a million tons? Have you ever wondered how snowflakes become ice? And what’s the albedo effect?

The Center for Remote Sensing of Ice Sheets (CReSIS) has the answer to such questions and much, much more. Over the past four years, CReSIS has been developing technologies, conducting field investigations and compiling data to help understand the rapid changes in the polar ice sheets in Antarctica and Greenland. In conducting this research, their vision is to one day understand and predict the role of polar ice sheets in sea level change.

A total of five multi-disciplinary teams work together to conduct research allowing for efficient and well-coordinated progress. I took a closer look at the Satellite Measurements team and the instrumentation they’re using is quite fascinating. The instruments provide high-resolution information on everything from topography to temperature to surface melt. When comparing how these parameters change over time, the team can determine their effects on sea level, identify potential mechanisms controlling that effect, and then create computational models that explain these changes. You can even follow the field experiments that the center is currently conducting at their blog.

On top of all of that, CReSIS is also helping to inspire, educate and train K-12, undergrad and graduate students by encouraging the pursuit of careers in science and engineering as well as offering a variety of research opportunities. My personal favorite is the Ice, Ice, Baby lessons activities. Who cares if its designed for K-8 students! If you’re looking for something to do on a rainy day, I highly recommend making glacier goo. You can learn a lot while making a mess!
