This  was a cruise in conjunction with scientists on board the UK  research                                                         
ship  RRS Discovery (Cruise 69).  It was organised jointly by the Institute

The instrument used was a Bathysonde Salinity-Temperature-Depth system. The                                                         
calibrations curves for the Bathysonde were determined to be:

Stations were identified by their 4 digit station number.
