|Amy Hansen taking a break to build a snowman. Arctic snow is far too dry and powdery to pack, but you can cut out styrofoam-like blocks!|

This ice auger is a different tool from the one we use to take ice core sections. Instead of collecting the ice, the auger lets us cut out holes through which we can lower various kinds of equipment. The tricky part is that we have to drill several holes side by side to achieve a hole wide enough to use anything larger than the underwater camera. This is much harder than it sounds.
|See the ice bridge in the lower left? That's not conducive to lowering large equipment into the water.|

Speaking of algae, here's a shot taken through the eyepiece of our lab microscope of a dense sample of ice algae. Most of the organisms you see are diatoms, single-celled photosynthetic organisms with cell walls made of silica.
The algae carpet the bottom of our ice cores, as evidenced by this photo:
In an earlier post, we mentioned the pure blue ice you find breaking the monotony of the largely barren, colorless Arctic landscape.
|The exterior of this block is covered in snow, but you can see the blue interior through a crack in the ice.|
