Abstract:

LONG-TERM GOALS - To conduct high-latitude glider surveys that will lead to i enhanced autonomous observational capabilities in the high Arctic, with focus on ii diapycnal fluxes of heat and salt which may have significant influence on the upper water column and sea ice, and iii provide direct measurements of the dissipation rate of turbulent kinetic energy. This is an important and critically undersampled parameter for numerical modeling of the coupled ice-ocean system.OBJECTIVES - To enhance the observational capabilities in the high Arctic by integrating and utilizing direct microstructure turbulence and current measurements onto existing AUV gliders as part of the large-scale NABOS program.
