Researcher Egbert Schwartz and PolarTREC teacher Justin Kendhammer will travel to the Dry Valleys of Antarctica in search of life in the seemingly barren soil. One of the questions they will attempt to answer is whether microbes in the soil are native to Antarctic soil or whether they have been blown onto the continent from elsewhere in the world.
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
