This one hour webinar is a great look at the PolarTREC 2014-5 Antarctic expeditions. Each teacher presents on the research projects, implementation in the classroom, and outreach into communities.
Note: This event was not for our typical classroom-based education audience.
WAIS Divide (West Antarctic Ice Sheet), where the Velvet Ice team conducted its research, has recently be found to be one of the most vulnerable areas of Antarctica to global climate change. If recent predictions hold true, major glaciers in WAIS could collapse within 100 years, triggering massive shifts
This one hour event is an introduction to the expedition with Yamini Bala and her team. They address life at McMurdo and what it will be like at their remote field site at WAIS Divide (West Antarctic Ice Sheet).
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
