Include units, scales, resolution, accuracy) Files contain 13 lines of header with a format of variable length character strings: ('h ',a), followed by the data with a format of (f7.1,4f8.3,f7.1,f8.3,f7.3, f6.1, f8.3, 2f8.2). The header contains: file name, latitude, longitude, time, bottom depth, station number, station name (may be blank), 2 comment lines, and the data column labels. The data includes: pressure (dbars), accurate to better than plus/minus 1 db temperature (C), accurate to plus/minus 0.01 C salinity (psu), accurate to plus/minus 0.004 psu potential temperature (C), Sigma-theta (kg/cubic meter), specific volume anomaly (cl/ton), geopotential anomaly (J/kg) fluorescence (0-5 v), light transmission (0-5 v) oxygen current (0-5 v) oxygen temperature (C) oxygen saturation (ml/l) #format_publication: * (a reference for any document which defines/describes the data format(s)) #format_comments: * (any information about the format that will be useful, but is not elsewhere on this form) #misc_documentation: * #submittor_documentation: * any textual information about the data, provided by the submitter, or investigator, (not NODC folks) For example, in most cases this has been an ASCII text file accompanying the data on a DAT , diskette, or CDROM. It may contain information which is redundant with other parts of this form. * leave blank
