This one hour live event is hosted by PolarTREC teacher Lisa Seff and her team studying the oceanographic conditions of bowhead whale habitat. The team is stationed in Barrow, Alaska.
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
