COARE CTD DataCOARE CTD data were collected using a SeaBird CTD 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 for EQ-1 can be found in HOT Data Report #1. Details of the CTD processing for EQ-2 and EQ-3 can be found in Shipboard Measurements from R/V Moana Wave during TOGA COARE Enhanced Monitoring Cruises Data Report. (To obtain a copies of these data reports, please contact Roger Lukas at the University of Hawaii at the address listed below).
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.
