1.0	Background

Thermosalinograph data was acquired on COARE EQ-1 (April 17, 1992 -
May 14, 1992) on the R/V Moana Wave. The thermosalinograph was mounted
to the R/V Moana Wave in the engine room with intake from the hull at
4m. 1 Hz data were acquired.

2.0	Factory sensor calibration

The following factory calibrations were used to convert the data to
engineering units.

TEMPERATURE: SEA-BIRD sensor number 621 was used. The 20 February 1992
calibration was used to calculate the temperature from the sensor
frequency. Assuming that the temperature sensor drifted linearly, the
correction was obtained from the 14 August 1986 and the 20 February
1992 calibrations. The correction of 0.0033C was applied.

CONDUCTIVITY: SEA-BIRD sensor number 235 failed on the first day of
operation. No spare was available, therefore, no data was acquired or
processed.

3.0	Processing

3.1	Gross error check:
	Detect out of range temperatures and use linear interpolation
        to replace them.

3.2	Running median filter:

	Use a 5 point running median filter to detect temperature
        glitches. If a glitch is found, the temperature of this record is
        immediately replaced by the median.

3.3	Triangular running mean filter
	Use a 3-point triangular running mean filter to smooth the edited 
        temperature.

3.4	Salinity
	Calculate salinity assuming pressure including pressure from the 
        pump is 20 dbar.

4.0	File format
	The 10 second thermosalinograph ACSII data file contains the 
        following to columns:


	Column 1: time (decimal Julian day since January 1, 1992)
	Column 2: temperature (C)

	FORTRAN Format: (f9.5, f8.4)
	C Format: "%9.5f %7.4f"

5.0	Futher information
	
Details of the processing can be found in Shipboard Measurements from
R/V Moana Wave during TOGA COARE Enhanced Monitoring Cruises Data
