This one hour event by Melissa Barker explains the research being done at Toolik Field Station, Alaska on nutrient transport in arctic watersheds. She is joined by team member Dr. Sarah Godsey.
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
