Thermosalinograph data are distributed in a format specified by this document.
The thermosalinograph data for each cruise are stored together with the navigation data in an ASCII file. The file names are determined by cruise name and number. For example, the thermosalinograph data for HOT-63 can be found in hot63ts.dat.
The thermosalinograph data files do not contain any header information. Only the data for each cruise are presented in the files. The order of variables in a thermosalinograph record are as follows: time (year, decimal year day), longitude, latitude, temperature, salinity and quality. Note, negative longitude corresponds to West longitude.
Data Record Format:
Column Variable
------- -------
1 Year
2 Decimal Year Day (January 1 = Year Day 0)
3 Longitude (decimal degrees)
4 Latitude (decimal degrees)
5 Temperature (Degrees Celsius,
International Temperature Scale of 1990)
6 Salinity (1978 International Practical Salinity Scale)
7 Quality (defined by investigator) **
FORTRAN FORMAT (i4, f10.5, f12.6, f11.6, f7.3, f7.3, i3)
** The quality word is the left-to-right concatenation of required
quality bytes for temperature and salinity; the first byte represents
temperature, the second represents salinity. Quality information is
only available for cruises after HOT-71.
The byte values are defined as follows:
byte value Definition
2 Acceptable measurement.
3 Questionable measurement.
4 Bad measurement.
