COARE EQ Water Sample DataWater sample data are written according to the *.sea files specified by the WOCE Hydrographic Programme Office, for submission of these data to the WHP.
Formats for these files 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.
The files are self-explanatory, one column is written for each measured parameter. Missing data are filled with -9. A 5-line heading labels each column.
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.
Variables having 7 asterisks on the 4th heading line have a quality flag associated with them. These 1-digit quality flags are concate- nated to form quality word which is listed as the last variable in each row. The values each digit can assume and their meanings are listed below:
Bottle quality flag definitions: Byte Value Definition 1 Not assigned. 2 No problems noted. 3 Leaking. 4 Did not trip correctly. 5-8 Not assigned. 9 Samples not drawn from this bottle. Water sample quality flag definitions: Byte Value Definition 1 Sample for this measurement was drawn from water bottle but analysis not received. 2 Acceptable measurement. 3 Questionable measurement. 4 Bad measurement. 5 Not reported. 6 Mean of replicate measurements. 7 Manual chromatographic peak integration. 8 Irregular digital chromatographic peak integration. 9 Sample not drawn for this measurement from this bottle.
