Description
Summary:<p>This is from the cruise report (see LGM1110 deployment page for link) and particulary pertains to the Fluorescence data that were collected:</p> <p><strong>\"Preliminary CTD Results</strong>: A total of 20 CTD stations were occupied and sampled during the cruise. Hydrographic data were collected in all sampling regions of the study. Casts were sent to the shallower of 1,000 m or 5-10 m above the bottom. The primary fluorometer was mis-calibrated (had the wrong scale factor in the calibration/processing file), so fluorescence data from the first four (or five) stations (Stns #22, #7, #8, #11) had to be re-processed with the correct scaling factor. Examination of the *.cnv file showed which casts had the miscalibrated data, as the max reading for fluorescence was ~ 0.05 mg/m3. For nearly every other station, maximum fluorescence readings were &gt; 1.0 mg/m3. A secondary fluorometer was added to the CTD rosette between Stns #11 and #12, which verified that the issue was with the scale factor in the CTD processing software.\"</p> <p>The data that are served have warnings about fluorescence numbers in the headers of the casts at Stations 22, 7, 8 and 11.</p> <p>Variables that were part of the data that have been rendered invisible from the data online are: Elapsed time in seconds, modulo error count (always zero), and nbin (number of scans per bin). Those numbers are available upon request.</p> <p>IEDA has published a DOI for another version of this dataset: 'Bucklin, A., (2015).
