CTD profile basic hydrographic data
No documentation was provided with these data.
The PI did confirm that these data were acquired using a Seabird 911 model CTD. The DMO made logical guesses for parameter definitions and units. The reported value for 'seafloor' is 1000 for every station location. The DMO suspects that this is not the actual depth of the seafloor.
The stations are reported from leg 2 of the cruise, stations 2-1 through 2-9, and the date range is 6 June 2005 through 3 July 2005, with the deepest station to about 1000 meters.
