Adventures on the sea ice!

Saturday Kyle and I had the adventure of a lifetime exploring the sea ice with our bear guard and scientist Dr. Tom Douglas (U.S. Army Cold Regions Research & Engineering Lab), graduate student Ross Lieb-Lappen (Dartmouth College), graduate student Melinda Webster (Univ. of Washington), and graduate student Erin Gleason (Univ. of Alaska, Fairbanks).  We took the snowmobiles ~1 mile out onto the sea ice to measure and collect brinecicles - salty icicles that form below uplifted chunks of deep blue sea ice.  Here are a collection of photos from our adventure!
