Ice that forms in the polar oceans is an important driver behind the global climate. This ice is physically different from frozen precipitation in a number of different ways. In this brief inquiry activity, students make qualitative observations about two types of ice cubes and deduce ice composition based on their observations. This activity may serve as an introduction to
Presentation prepared for the Rochester Community Schools Board of Education related to the PolarTREC 2017 Neutron Monitors for Solar Study expedition.
Video created by PolarTREC teacher Bill Schmoker onboard the International Continental Shelf Survey. This was the first piston core that returned a gas hydrate sample in the core cutter. The hydrate was about 20 feet beneath the sea floor. Once on deck it began fizzing with escaping methane. Gas hydrates turn out to be very widespread throughout the world's oceans
Boat opps aboard the USCGC Healy during the 2010 International Extended Continental Shelf Survey, filmed by PolarTREC teacher Bill Schmoker. Here we see the launch and deployment of the Arctic Service Boat.
Breaking heavy ice in the Canada Basin (northern Arctic Ocean) aboard the USCGC Healy during the 2010 International Extended Continental Shelf Survey. In the distance notice the Canadian Coast Guard Cutter Louis S. St. Laurent. Filmed by PolarTREC teacher Bill Schmoker.
Deploying an ice buoy from the USCGC Healy in the Beaufort Sea. The buoy drifts with the ice pack and relays its position to a satellite and so can be used to monitor ice movement. Filmed by PolarTREC Teacher Bill Schmoker on the 2010 International Extended Continental Shelf Survey.
