Did you see the spectacular image of Alaska that was taken on June 17th by NASA’s MODIS satellite? Click here< to see the cloud-free image of Alaska that captures wildfires, snow, water, ice, and large plumes of sediment entering the Gulf of Alaska. Alaska’s grand landscape is breathtaking from space, land, and sea. We are currently drilling into the continental shelf, approximately 22 miles from the mainland and can see this beauty firsthand. From the ship we can see the breathtaking snow-capped peaks of the Chugach and Wrangell-St. Elias Mountains, and when the cloud curtain isn’t masking our view we have a spectacular view of Mt. St. Elias (18,008 ft) to the northeast and the Bering Glacier to the northwest.

There are a lot of microfossils in oceanic sediments and they provide a basis for age determination. The paleontologists studying sedimentary sequences have established first appearences and extinction of species through time.
