There are times and there is a list of site #s and positions. For most files the site # was entered into the original file name, so a rough position can be determined, though there is no assurance that each visit to the site stopped at exactly the same place. For some casts there was no record of site # and positions were inferred from order of sampling (assuming all casts are at standard sites), maximum pressure and T-S characteristics. The times and site #s thus determined were confirmed by the chief scientist from his records and bridge logs. In the absence of a log book and given the unreliability of time from this instrument, the times for all these casts should be considered approximate. There was no salinity calibration sampling and no history for this instrument since its last calibration, so no estimate can be made of those errors. Salinity for this cruise has been edited but large errors likely remain. SeaCat salinity is prone to error due to mismatch of conductivity and temperature response times, especially when the descent rate is non-uniform. These errors are likely to be much larger than calibration errors. SeaCat salinity errors are expected to be as high as 0.05units in areas of high gradients. Below 5m salinity is likely +/-0.005psu. !--1--- ---2---- ---3---- -4-- !Pressu Temperat Salinity Numb !re ure: :T0:C0 er_o !
