Abstract:

As a contribution to the Marginal Ice Zone ORI, this research element was designed to observe the seasonal evolution of the upper-ocean stratification. document the time-varying ocean currents and characterize the turbulent ice-ocean exchanges of heat, salt and momentum as the sea ice cover retreats poleward in springsummer using Ice-Tethered Profilers with Velocity. A total of 5 systems were deployed for MIZ, programmed to acquire vertical profiles of upper-ocean temperature, salinity and horizontal velocity at 3 hour resolution, as well as direct vertical turbulent flux estimates from just below the ice-ocean interface several times per day. Results advance understanding of the Arctic air-ice-ocean system.
