Subsurface temperature data consist of cruise information record (HEADER) and subsurface temperature data records (DATA) obtained during the cruise. The "REC_IND" field definition is the same as one in the hydrographic data.

HEADER (Cruise Information)
Element Start Position Field Type Description of Field
FORMAT CODE 1 A4 Format Code of the file: 'T1.2'
CRUISE NO 6 I4 Cruise number identified with the year and the month.
PERIOD 11 2(2I2,1X) Date of beginning and end of the subsurface temperature observations.
AREA 21 A98 Observation area.
NO OF STN 119 I4 Number of stations.
SHIP CODE 124 A2 Ship Code (listed in Table)
REC_IND 126 A1 '@'
