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 was conducted with PolarTREC teacher Claude Larson, and members of the research team that she worked with on the Prehistoric Human Response to Climate Change 2010 project in Kamchatka, Russia.
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.
