CalCOFI Information Archive

CalCOFI CTD Data are available in three zipped filetypes:

Cast = raw Seabird cast files;
Prelim = Seasoft-processed asc files; may include preliminary bottle-corrected CTD csvs
Final = Seasoft-processed asc files with bottle data & bottle-corrected CTD data as CTD.csvs; database-ready upcast & downcast csvs.
"FinalQC" files include additional quality-control code columns - latest format is 82-columns. These additional columns were added Nov 2015 but older cruises are being reprocessed so look for "finalQC" for the 82-column updated files.Final CTD data values should not change during the conversion from 65 to 82 columns. But data codes may be added to bad or missing sensor data (datacode '9') and questionable sensor data (datacode '8') in the corresponding "Q" column.

Please note that CTD data from Mar 1990 - 1991 were system & feasibility tests; 1992 CTD casts were performed on daily prodo stations only. The first complete cruise using the CTD-Rosette was August 1993 - CalCOFI 9308NH

Another important note: the Windows-version of Seabird's SBE Data Processing Suite will not work on CTD data collected from 1990 to mid-1998. Those data must be processed by the DOS version of Seasoft, which can be successfully run in DOSBox on Windows 7 & 10.

First complete CalCOFI cruise using CTD-Rosette on all stations was 9308NH (Aug 1993). The Seabird 911 CTD was first tested in Mar 1990 (9003JD) but still under development. Niskin, Nansen, & "Wally" (in-house design by Walt Bryant & George Anderson) bottles with reversing thermometers were the primary method of seawater sampling until 9308NH. As confidence in data quality, time-series continuity and relability improved, the CTD-rosette was used for daily primary productivity sample collection casts (6 depths) in 1992: 9202JD, 9208NH, & 9210NH.

Some older cruises may not have final data available since they are being reprocessed using the current data-processing methodology for data-format continuity. All raw Raw CTD Data data files are available but processed - either preliminary or final bottle-corrected - will be posted when completed.
