Originator's Protocol
Independent temperature samples were recorded by two SiS RTM 4002X reversing thermometers (instruments s/n T1563 and s/n T1590). These reversing thermometers were attached to a rosette bottle on the RV Prince Madog carousel water sampler. Samples were collected near-bed during all casts. When the carousel was returned to the surface, the recorded temperatures and standard deviations were read off each reversing thermometer and noted on a CTD logsheet. 35 samples were taken at 35 CTD stations during cruise PD020_02.
BODC Processing
The data were supplied to BODC on CTD logsheets. The mean of these temperature values was extracted from these sheets and entered into an Excel spreadsheet. This was converted to an ASCII format file for loading into the BODC archive. Methodology and units were checked against information held in the BODC parameter dictionary and an appropriate parameter code was attributed to each variable. The file's data and metadata fields were then checked prior to loading into a database.
The data were loaded into the database under the Oracle Relational Database Management System by matching the sample's station identifier and depth with the information already held in the database for this cruise. The data were successfully loaded without further modification.
Comments
The values for casts C01 and C02 have been flagged 'M' as they are data from reversing thermometer T1590 only and do not represent an average value of both instruments.
