Science objectives

The purpose of the cruise is to acquire full water column profiles of temperature, salinity, pressure, oxygen and velocity using a shipboard CTD/rosette and the High Resolution Profiler (HRP-II), plus detailed bathymetry (with SeaBeam)  across a variety of topographic features between Guadeloupe,  the mid Atlantic Ridge and Bermuda Rise.  These data will be used to investigate the strength of turbulent mixing, deep properties and flows across the region of study and their relationship to seafloor topography.

Science Activities

~ 120 HRP deployments
~ 70 CTD/rosette stations, with water samples for salinity, oxygen, nutrients
SeaBeam survey

Pre-cruise planning meeting: Visit WHOI

Curry and Polzin will meet with Marine Ops personnel.
