USCGC Healy experiencing the first ice of 2010 International Extended Continental Shelf Survey in the Bering Sea. Filmed by PolarTREC teacher Bill Schmoker.

Launch & recovery of the RHI (rigid-hull inflatable) boat aboard the USCGC Healy in foggy conditions. Filmed in the Canada Basin (northern Arctic Ocean) during the 2010 International Extended Continental Shelf Survey by PolarTREC teacher Bill Schmoker.

Gas (methane) Hydrate ice recovered in core catcher during bottom sampling opps aboard USCGC Healy in the Southern Beaufort Sea during the 2010 International Extended Continental Shelf Survey. Filmed by PolarTREC teacher Bill Schmoker.

Conducting gravity coring operations aboard the USCGC Healy in the Southern Beaufort Sea during the 2010 International Extended Continental Shelf Survey. This is a simple way to retrieve soft sediment cores- the coring pipe is driven into the sea bed by the 2-ton weight at the top of the coring device. Filmed by PolarTREC teacher Bill Schmoker

Black-legged Kittiwakes are joined by an immature Herring Gull (maybe Vega Gull??) in the Canada Basin (northern Arctic Ocean). Filmed aboard the USCGC Healy on the 2010 International Extended Continental Shelf Survey by PolarTREC teacher Bill Schmoker.

Helicopter transfer via Canadian Coast Guard MBB Bo 105 from USGCC Healy to Canadian Coast Guard Cutter Louis S. St. Laurent in the Canada Basin (N. Arctic Ocean) during the 2010 International Extended Continental Shelf Survey. Filmed by PolarTREC teacher Bill Schmoker

PolarTREC teacher Bill Schmoker gives a walking tour of the USCGC Healy in the Canada Basin (N. Arctic Ocean) on the 2010 International Extended Continental Shelf Survey.

USCGC Healy breaking ice in the Canada Basin (N. Arctic Ocean.) Filmed from the Canadian Coast Guard Cutter Louis S. St. Laurent by PolarTREC teacher Bill Schmoker on the 2010 International Extended Continental Shelf Survey. Here the Louis is stopped for sonar repairs and the Healy is prepping a clear lane for the eventual resumption of sonar subseafloor profiling.

Helicopter transfer between the Canadian Coast Guard Cutter Louis S. St. Laurent & USCGC Healy in the Beaufort Sea. This is a MBB Bo 105 helicopter, a twin-engine craft with 4 rotor blades. Filmed by PolarTREC teacher Bill Schmoker on the 2010 International Extended Continental Shelf Survey.

USCGC Healy entering the ice pack north of Barrow in the Canada Basin. Note the paint scraped off on one large piece of ice and the Canadian Coast Guard Cutter Louis S. St. Laurent following us into the ice. Filmed by PolarTREC teacher Bill Schmoker on the 2010 International Extended Continental Shelf Survey.
