<p>Seward Johnson cruise <strong>SJ9508</strong> 6 - 16 June 1995; using the (NBIS Mark III) CTD system.</p>

<p>Calibrated CTD files were prepared by R. Limeburner except for stations 1, 37, 51 and 61 which were processed by Russ Burgett, URI.</p>

<p>There was no station 95 for this cruise.</p>

<p>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.</p>

<p>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.</p>

<p>Seward Johnson cruise <strong>SJ9508</strong> 6 - 16 June 1995; using the (Seabird SBE-25) CTD system.</p>

<p>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.</p>
