COARE EQ-3 CTD data

COARE EQ-3 CTD data were collected using a SeaBird CTD 9-11plus
at the maximum sampling rate of 24 samples per second (24 Hz). 
They were screened for errors and processed to 2-dbar averages. 
Details of the CTD processing can be found in Shipboard Measurements
from R/V Moana Wave during TOGA COARE Enhanced Monitoring Cruises
Data Report. (To obtain a copy of this data report, please contact

CTD data are written to files using formats specified by the
WOCE Hydrographic Programme Office. These formats are based on
NODC formats, and are detailed in the WHP Office Report WHPO
90-1, available from Dr. Terrence Joyce, Director, WHP Office,
Dept. of Physical Oceanography, WHOI, Woods Hole, MA 02543.

Data consist of pressure, temperature and salinity for all
casts. Details of this format are given in the file Readme.format.
Briefly, the format consists of a self-documenting header followed
by the data.  The data records are written so that they can be read 
with a simple FORTRAN read statement. 

Temperatures are reported in ITS-90 units. Since temperature
sensor calibrations were done in IPTS-68 units, and the UNESCO
routines require IPTS-68 temperature, all intermediate
processing was done in IPTS-68. As a final step, temperature and
potential temperature were converted to ITS-90 using
t_90 = 0.99976 t_68.
