CHARLES ISELIN CRUISE 9407, CTD DATA QUALITY REVIEW

GENERAL COMMENT: THIS DATA SET IS OF POOR QUALITY, USE "CAUTION".

1..CAST SAMPLING INFORMATION EDITED TO BE CONSISTENT WITH THE EVENT LOG. DATES AND TIMES ARE REPORTED AS GMT.
2..CASTS 96 AND 98 CONTAIN ONLY A SURFACE DATA CYCLE. FILES DELETED. 3..OXYGEN BAD ALL CASTS. REPLACED WITH -9..
4..SALINITY IS NOISY. SOME CASTS WORSE THEN OTHERS. NO ATTEMPT TO CLEAN UP. USE WITH CAUTION.
5..LIGHT TRANSMISSION. CASTS 68 - 99 SHOW A ONE VOLT OFFSET FROM CASTS 1-68. CALIBRATION PROBLEM? USE WITH CAUTION. NO ATTEMPT TO CLEAN UP SPIKES.
6..FLUORESCENCE. CASTS 68 - 99 SHOW A TWO VOLT OFFSET FROM CASTS 1 - 68. CALIBRATION PROBLEM? USE WITH CAUTION. NO ATTEMPT TO CLEAN UP SPIKES.

ENDEAVOR CRUISE 259, CTD DATA QUALITY REVIEW

1..CAST SAMPLING INFORMATION WAS EDITED TO BE CONSISTENT WITH THE EVENT LOG. DATES AND TIMES ARE REPORTED AS GMT.
2..NO CTD CAST 20. APPEARS TO BE THE RESULT OF MIS-NUMBERING.
3..CTD CAST 13 HAS ONLY ONE DATA CYCLE, SURFACE VALUE. FILE DELETED.
4..CTD CAST 27. THE DATA REPORTED FOR CAST 27 IS THE EXACT SAME AS FOR CAST 28. THE FILE FOR CAST 27 DELETED.
5..CTD CAST 29. FLUOROMETER DATA BAD ENTIRE CAST, REPLACED WITH -9.0 BAD/MISSING DATA INDICATOR.
6..CTD CAST 30. TRANSMISSOMETER DATA, DATA SPIKE AT 274 DECIBARS. REPLACED WITH -9.0.
7..OXYGEN DISPLAYS OCCASIONAL DATA SPIKES AND SHIFTS EXTENDING OVER MORE THEN ONE DECIBAR. NO ACTION TAKEN

ENDEAVOR CRUISE 260, CTD DATA QUALITY REVIEW

1..CAST SAMPLING INFORMATION WAS EDITED TO BE CONSISTENT WITH THE EVENT LOG. DATES AND TIMES ARE REPORTED AS GMT.
2..CAST NUMBERS 26, 27 AND 28 MISSING.
3..OXYGEN DISPLAYS OCCASIONAL DATA SPIKES EXTENDING OVER MORE THEN ONE DECIBAR (CAST 13 AT 110 DECIBARS, AND CAST 16 AT 41 DECIBARS). NO ACTION TAKEN.

ENDEAVOR CRUISE 262, CTD DATA QUALITY REVIEW

1..CAST SAMPLING INFORMATION EDITED TO BE CONSISTENT WITH THE EVENT LOG. DATES AND TIMES ARE REPORTED AS GMT.
2..CAST NUMBERS 20, AND 21. ALL OXYGEN VALUES BAD. REPLACED WITH -9..
3..LIGHT TRANSMISSION. ONE DECIBAR DATA SPIKES REMOVED FROM CAST 2, 5 AND 23, SURFACE VALUES. A ONE DECIBAR SPIKE REMOVED FROM CAST 21 AT 14 DECIBARS.
4..FLUORESCENCE. DATA SPIKE REMOVED FROM CAST 21 AT 14 DECIBARS.

ENDEAVOR CRUISE 264, CTD DATA QUALITY REVIEW

1..CAST SAMPLING INFORMATION EDITED TO BE CONSISTENT WITH THE EVENT LOG. DATES AND TIMES ARE REPORTED AS GMT.
2..CAST NUMBERS 29, 30, 32, AND 34 MISSING.
3..LIGHT TRANSMISSION. ONE DECIBAR DATA SPIKES REMOVED FROM CAST 2 AT 10M, AND CAST 23 AT 88M.

ENDEAVOR CRUISE 266, CTD DATA QUALITY REVIEW

1..CAST SAMPLING INFORMATION EDITED TO BE CONSISTENT WITH THE EVENT LOG. DATES AND TIMES ARE REPORTED AS GMT.
2..DATA FOR CAST NUMBERS 22, AND 23 MISSING.

ENDEAVOR CRUISE 267 LEG 1, CTD DATA QUALITY REVIEW

1..CAST SAMPLING INFORMATION EDITED TO BE CONSISTENT WITH THE EVENT LOG. DATES AND TIMES ARE REPORTED AS GMT.
2..DATA FOR CAST NUMBERS 4, 98, AND 103 MISSING.
3..CAST 1 AND 81 ALL VALUES REMOVED FROM LAST DATA CYCLE DUE TO DATA SPIKES.
4..FLUORESCENCE. DATA OFF SCALE ON THE HIGH SIDE. SEVERAL CASTS EXCEED THE MAX. OF VALUE OF 5 VOLTS.

ENDEAVOR CRUISE 267 LEG 2, CTD DATA QUALITY REVIEW

1..CAST SAMPLING INFORMATION EDITED TO BE CONSISTENT WITH THE EVENT LOG. DATES AND TIMES ARE REPORTED AS GMT.
