The PI group seeks to observe the upper Arctic Ocean using autonomous instrumentation and build understanding of the physical processes controlling the evolving thermohaline stratification, the ocean currents and air-ice-sea interactions on time scales of minutes to interannual. This award is supporting the acquisition of 4 Ice-Tethered Profilers with Velocity (ITP-V) instruments as a contribution to the Marginal Ice Zone DRI. This specific research element is 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 spring/summer.
