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.

This Live from IPY! event was with PolarTREC Teacher Gerty Ward, and scientists Sarah Zimmerman, Rick Krishfield, and Brian Hunt who are all participating in oceanographic research on board the CCGC Louis S. St-Laurent on the Beaufort Sea.
There were about 120 people in attendance.
The beginning part of the presentation is composed of recordings from Gerty Ward and the
Online version of The News & Observer news paper article highlighting Gerty Ward's participation in a PolarTREC expedition on the Beaufort Sea. Gerty will be working with Rick Krishfield and other scientists on a Canadian icebreaker studying ocean currents and more!
