CTD Processing Notes and Comments:
Re: SJ9506
Seward Johnson cruise SJ9506 25 Apr - 3 May 1995; using the (NBIS Mark III) CTD system.
Calibrated CTD files provided by R. Limeburner, WHOI.
Re: SJ9508
Seward Johnson cruise SJ9508 6 - 16 June 1995; using the (NBIS Mark III) CTD system.
Calibrated CTD files were prepared by R. Limeburner except for stations 1, 37, 51 and 61 which were processed by Russ Burgett, URI.
There was no station 95 for this cruise.
Examination of the files showed the salinity (and sigma_t) to be suspect. The salinty and sigma_t fields have been manually edited and obvious problems marked as no data (nd), however care should be taken when using the salinity and sigma_t from these files. Pressure, temperature, salinity and sigma_t from a SeaBird CTD added to the Seward Johnson CTD package are available for casts 112-114, 116, 124-128, 130-136, 138-140, 142-151, 153-160, 162, 164-172, and 174-185. It is recommended to use these files when possible. They are available as a separate object.
Examination of the unprocessed CTD files showed a 4 dbar pressure offset in the CTD calibration. This offset was added to the pressure in the calibrated files.
Re: SJ9508sb
Seward Johnson cruise SJ9508 6 - 16 June 1995; using the (Seabird SBE-25) CTD system.
The Seabird CTD was added to the Seward Johnson CTD package after cast 111 due to poor quality conductivity data. Seabird casts 112-114, 116, 124-128, 130-136, 138-140, 142-151, 153-160, 162, 164-172, and 174-185 are available in this data set.
