<p>AR16 CTD Data collection notes.</p>
<p>Casts 1-10 - PAR sensor calibration numbers incorrect in .xmlcon files for each cast #</p>
<p>Casts 1-4 - collected with ar16_initial.xmlcon (data values really wrong)</p>
<p>Casts 5-10 - collected with ar16_test.xmlcon - data close, but not using the correct cal coefficients for surface par</p>
<p>Casts 11 --> onward collected with ar16.xmlcon - data correct, real calibration numbers.</p>
<p>***** all casts processed with the correct configuration file and calibration coefficients. The originally collected cast-associated .XMLCON files have not been deleted, but are incorrect as above for the first ten casts. If reprocessing done, use ar16.xmlcon.*****</p>
<p>APPROPRIATE REPROCESSING CONFIGURATION FILES AND CAST #S.<br />
After cast 11, the associated cast# .xmlcon file is correct. Also:</p>
<p>ar16_casts1to47.xmlcon<br />
ar16_casts48to60.xmlcon<br />
ar16_casts61plus.xmlcon</p>
<p>can be used for the various cast ranges.</p>
<p>After cast 39 - changed pump on primary side to alleviate sensor clogging issues that showed up in oxygen and conductivity.</p>
<p>Perhaps cast 39 not ended? The .bl file time did not end until the next cast started. Replaying the cast shows the bottles firing nevertheless.</p>
<p>Fluorometer (FLNTURTD) started to exhibit strange drift characteristics, trending negative data, and a regular voltage spike pulse around cast 34. After troubleshooting, the cause was determinted to be failing voltage channels 0-1. The FLNTURTD (voltage 0-1) and transmissometer (voltage 2-3) cables were swapped on the 9plus CTD voltage channels after cast 47. This fixed the FLNTURTD instrument. The transmissometer was not removed from the package until after cast 60. The intervening transmissometer data should not be trusted.</p>
<p>Late in the cruise, the fluoromter started showing regular spiked data again (no drift). The problem was determined to be a faulty cable. As there was a no spare cable aboard for the FLNTURTD, but there was a spare cable on board for the ECO-AFL - the last three casts contain fluoromter data but none from the turbidity channel.</p>
