As final data is calibrated after raw data has been edited, the parameters actually used for calibrating raw data have been lost. (Dec., 1987) There are 4 bits in each number to represent which channel that the number shall be in (Vax : bit 12-15, Sperry: bit 21-24). The 16 data channels are numbered from 0 to 15 : Blank, Volt. reference, Press. supp., Press. offset, Temp. supp., Temp. offset, Cond. supp., Cond. offset, Blank, Blank, Press. supp., Press. offset, Temp. supp., Temp. offset, Cond. supp., and Cond. offset. Data file is formatted as 16I6. Note that the number which appears in column 1 may not be channel 0 (because record may be out of sync.) Example : the address bit of number 7770 indicates it is channel 1, hence it is Volt. reference. (7770= 0001 1110 0101 1010) (on the VAX, bit 12-15 of 7770 is 0001) Dummy values are used for 'INSTRUMENT SERIAL NUMBER' and 'DEPTH OF WATER'. *ADMINISTRATION MISSION : 1979-73 AGENCY : IOS, Frozen Sea Research Group, Sidney, B.C.
