Abstract:

This cruise was completed from May 10, 2012 to May 15, 2012, starting from and returning to Cocodrie, LA. Moorings were deployed at six different locations, to measure temperature, salinity and velocity profiles, all at different levels in the water column. These moorings are planned to be recovered after a year. In addition, 36 rafos floats were deployed to drift at a 300 meter depth, also for a year. Last, a section of 14 CTD casts were performed, from the surface to the bottom, at the location of the moorings and along the De Soto Canyon axis.
