<p><strong>CHARLES ISELIN CRUISE 9407, CTD DATA QUALITY REVIEW</strong></p>

<p>GENERAL COMMENT: THIS DATA SET IS OF POOR QUALITY, USE \"CAUTION\".</p>

<p>1..CAST SAMPLING INFORMATION EDITED TO BE CONSISTENT WITH THE EVENT LOG. DATES AND TIMES ARE REPORTED AS GMT.<br />
2..CASTS 96 AND 98 CONTAIN ONLY A SURFACE DATA CYCLE. FILES DELETED. 3..OXYGEN BAD ALL CASTS. REPLACED WITH -9..<br />
4..SALINITY IS NOISY. SOME CASTS WORSE THEN OTHERS. NO ATTEMPT TO CLEAN UP. USE WITH CAUTION.<br />
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.<br />
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.</p>

<p><strong>ENDEAVOR CRUISE 259, CTD DATA QUALITY REVIEW</strong></p>

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

<p><strong>ENDEAVOR CRUISE 260, CTD DATA QUALITY REVIEW</strong></p>

<p>1..CAST SAMPLING INFORMATION WAS EDITED TO BE CONSISTENT WITH THE EVENT LOG. DATES AND TIMES ARE REPORTED AS GMT.<br />
2..CAST NUMBERS 26, 27 AND 28 MISSING.<br />
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.</p>

<p><strong>ENDEAVOR CRUISE 262, CTD DATA QUALITY REVIEW</strong></p>

<p>1..CAST SAMPLING INFORMATION EDITED TO BE CONSISTENT WITH THE EVENT LOG. DATES AND TIMES ARE REPORTED AS GMT.<br />
2..CAST NUMBERS 20, AND 21. ALL OXYGEN VALUES BAD. REPLACED WITH -9..<br />
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.<br />
4..FLUORESCENCE. DATA SPIKE REMOVED FROM CAST 21 AT 14 DECIBARS.</p>

<p><strong>ENDEAVOR CRUISE 264, CTD DATA QUALITY REVIEW</strong></p>

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

<p><strong>ENDEAVOR CRUISE 266, CTD DATA QUALITY REVIEW</strong></p>

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

<p><strong>ENDEAVOR CRUISE 267 LEG 1, CTD DATA QUALITY REVIEW</strong></p>

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

<p><strong>ENDEAVOR CRUISE 267 LEG 2, CTD DATA QUALITY REVIEW</strong></p>

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

<p><strong>ENDEAVOR CRUISE 269, CTD DATA QUALITY REVIEW</strong></p>

<p>1..CAST SAMPLING INFORMATION EDITED TO BE CONSISTENT WITH THE EVENT LOG. DATES AND TIMES ARE REPORTED AS GMT.<br />
2..CAST 30, FLUORESCENCE DATA SPIKE AT 69 METERS REMOVED.<br />
3..OXYGEN VERY NOISY (LARGE NUMBER OF SPIKES). NO ACTION TAKEN. USE WITH CAUTION.</p>
