Will fresh water turn into ice when it is dunked in the chilly waters of the Canada Basin? Find out with PolarTREC teacher Bill Schmoker, aboard the USCGC Healy on the 2010 International Extended Continental Shelf Survey.
The Canadian Coast Guard Cutter Louis S. St. Laurent working in the Beaufort Sea, seen from the USCGC Healy on the 2010 International Extended Continental Shelf Survey. Note the bubbler system at the bow of the Louis, which enhances its icebreaking capabilities by lifting ice around the bow and wetting the surface of the ice. Filmed by PolarTREC teacher Bill

Density currents drive 3D movements within the world’s oceans that dwarf surface currents by volume. Density-driven movements due to temperature/salinity differences keep the world’s oceans well mixed & help to re-distribute heat from tropical areas towards polar areas. Resultant upwelling creates some of the world’s richest ocean ecosystems. Density movements known as turbidity currents are the world’s largest
Many students are familiar with topographic maps showing relief of land surfaces. In this lab they will produce their own bathymetric maps, the underwater equivalent. A bathymetric map shows sea floor features by contouring depths below sea level (instead of elevation above sea level as in topographic maps). Students will first probe depths in “Mystery Bay”, a box
This PolarConnect event with PolarTREC Teacher Bill Schmoker working onboard the US Coast Guard Cutter Healy was held with Centennial Middle School in Colorado. This event was closed to the public and does not have a Wimba archive.
