MOCNESS CTD variable names and units vs. GLOBEC Thesaurus


Pressure was sometimes stated as debars, sometimes as millibars.  It was always in decibars.

Pressure (unknown units):  these are decibars as are all measurements.
CH125	- 8/75 

Pressure (millibars):
KN65 ? 4/77 [added comments to .nm files that this is error, should be decibars. njc]

Pressure (decibars):
KN53	-11/75
KN62 [added comments to .nm files that this is error, should be decibars. njc]
EN11 ? 8/77
KN71 ? 11/77 [added comments to .nm files for mocs 104-117 that this is error, should be decibars. njc]


MAQUI75  (Polloni)  (for Chain-125), probably also  AT85, KN53 

Date: day, month, year (eg. 18 8 75 = 18Aug1975))
Time: hours, comma, minutes
Pressure  in millibars??? - no

6 calibration constants
1.  Conductivity calibration (millimhos): .0009999999Zg(1+0*P)  =>.0009999999*Zg
2.  Pressure : decibars (1db=1m)
	Press. Calib: .05*Zp-5.5
3.  Temp: degrees C.
4.  Temp. calib.: .016+.0050012*Zt
5.  Temp probe time C (secs)
6.  Lag of temp probe (# scans)
Flow calibration factor is in meters (4.7000) 

Magnetic tape format: 
	Record #
	Current time, hours and minutes in 24 integer form
	Current time in 1/60-of-a-second units (binary integer)
	Total # scans lost during the record
	Id tag (integer), inserted manually
	P, T, C, Fl
	Termination record: time, etc.
