Dr. Adams, Matt Heddin, and myself climbed aboard a helicopter this morning and crossed the McMurdo Sound for another one of Antarctica's Dry Valleys. Garwood Valley was our destination. I will not try and explain my day to you in words. It could not be done. My hope is that this little video can convey some of the beauty and science I experienced today. Enjoy the beauty of this special place.

How long ago were the volcanoes active? Is it possible that the volcanoes are the key to the life in Antarctica puzzle? Also, is it possible that types of cyanobacteria like the type shown in the video are what could be decomposing the mummy seals?

Kevin Dickerson replied:

Mt. Erebus, the volcano that is on the same island as McMurdo (Ross Island), is still active. We see steam rising off of it's summit most days. Yes, scientists think that the volcanoes might have played an important roll in the life of Antarctica. Volcanoes might have been another type of nunatak which could have held it's isolated ecosystem. A nunatak is a mountains that have been above the ice. Kind of like an island in the ocean.
