PolarTREC (Teachers and Researchers Exploring and Collaborating) is a program in which formal and informal educators spend 3-6 weeks participating in hands-on field research experiences in the polar regions. The goal of PolarTREC is to invigorate polar science education and understanding by bringing educators and polar researchers together.
This graphic is a summit ice core timeline depicting the phenomena that as we drill deeper ice cores, the ice gets older. The graphic compares this timeframe with major milestones in history. It is a concept developed by Zoe Courville and Dr. Mary Albert at Dartmouth University, in partnership with CRREL (Cold Regions Research and Engineering Laboratory).
Nature creates its own density column in marine systems, which is extremely important for the triggering of the spring bloom of phytoplankton. Phytoplankton are an important food source for all organisms- from microscopic zooplankton to large marine mammals such as walrus and whales. The different salinities (and therefore, different densities) of water help to stabilize the water column (by limiting
