General CTD Notes - data acquisition notes, logistics, processing - see below. Please note that these regressions are generated from preliminary CTD vs bottle data and will NOT be reprocessed since final bottle data will not be processed. This was a test cruise and minimal bottle samples were collected. CTD sensor data are good and have been processed normally. Both primary & secondary sensor profiles vs bottle data have been generated and archived in the downloadable CTD+Bottle data files. These plots are under the "csv-plots\Primary" & "csv-plot\Secondary" subdirectories. Please note: if re-processing the CTD raw cast data, the RV Sally Ride deck unit used was misconfigured, offsetting the primary and secondary conductivity 0.73sec instead of 0.073sec. An offset of -0.657sec should be applied using AlignCTD to calculate salinity correctly. These will not be imported into the CalCOFI database or processed into final form. They are provided as an archive. |
