CTD Data Processing Protocol.

Abstract

Please note, the processing methods described use SIO-CalCOFI-developed software (DECODR & BtlVsCTD) to merge and correct Seabird 911+ CTD data with bottle samples. The Seasoft portion of our data processing protocol follow their recommended settings for our 911+ v2 CTD & deck unit. "Sta.csvs" are bottle data collected at each station cast combined with 1m binavg CTD data from matching bottle depths (~20). Preliminary comparisons & plots of CTD sensor data versus bottle data are generated after each cruise. These comparisons are used to point-check the bottle data and QC the CTD sensor data. Once final bottle data are generated, eliminating fliers & mistrips, a final comparison of 1m binavg CTD to bottle data is performed. This generates final CTD data csv files for each cast that contain 1m binavg Seasoft-processed CTD sensor data, bottle-corrected Seasoft-processed CTD sensor data, and final bottle data.
