Students will find an expedition within the PolarTREC archives and use the research to make a video explaining why studying polar science is important.
Overview
PolarTREC supports teachers on expeditions with real scientists to study in the field. Studying in the Arctic and Antarctic environments can be a harsh and rewarding experience. I participated in Operation IceBridge, an aerial study
Operation IceBridge is an aerial survey that measures both land and sea ice in the Arctic and the Antarctic. There are many reasons to monitor the polar regions. The cryosphere is essential in helping to maintain global climate. One important reason is to investigate sea level rise. Land ice can cause sea levels to rise, when it melts, by adding
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
Lake El'gygytgyn (67.5º N, 172º E) is one of the best preserved large asteroid impact craters on earth. In the winter of 2009, I joined an international science team and traveled to the frozen arctic lake to drill and extract lake sediments to study climate change as well as sample the rocks that were changed when the crater
The sediment in Lake El'gygytgyn, (pronounced EL-ge-GIT-gin) located in NE Siberia, holds one of the longest records of climate change anywhere in the continental Arctic. How does sediment (clay and mud) tell us something about past climate? Proxy data! By studying the microfossils of diatoms and pollen in the sediment, we can re-construct the lake environment millions of
Lake El'gygytgyn (also called, Lake E) permafrost drilling started in mid-November of 2008. The ICDP (International Continental Drilling Program) is posting news reports and images to this blog several times each week. Check out early reports from Lake E.
