As we transit toward the next station with a speed of about 8 knots, we are taking continuous profiles of the upper 100 meters of the ocean. To do so we use a Moving Vessel Profiler (MVP), an instrument measuring temperature and conductivity (from which salinity can be derived) is free-falling in the ocean and then automatically pulled back to the surface.
The goal here is to survey the Labrador Current fronts, which are sharp changes in the temperature and salinity vertical structure over short distances, and the mixing of Labrador Current water with other water masses over the Labrador continental shelf. The Labrador Current is a water mass particularly cold, fresh, and high in dissolved oxygen.
