Observations of thermohaline sound speed structure in the Beaufort Sea in the summer of 2015

Observations of temperature and salinity were made by ship CTD casts and a mooring in the central Beaufort Sea between July 15 and August 15 2015, as part of the Canada Basin Acoustic Propagation Experiment (CANAPE) pilot study. This talk will present an analysis of the observed temperature, salinity, and sound speed structure in terms of the fresh upper layer, the Pacific layers, the Arctic halocline, and the Atlantic layer. The talk will focus on identifying the spatial and temporal variability of the thermohaline and sound speed structures associated with eddies, internal waves, and diffusive layering (stair cases).
