CalCOFI Preliminary CTD Database (v18May2012)
2009 - 2012 CalCOFI CTD data: 2009, 2010, 2011 (up to 1108) are final Seabird-processed, bottle-corrected 1m CTD data. Other cruises, 1110, 1202, 1203 data are preliminary ie CTD data are Seabird-processed but bottle-corrected using preliminary bottle data.

Final data

Those which have passed through the CalCOFI quality control process and have become publicly available. They differ from preliminary data in that the bottle data has been ammended leaving bottle versus CTD regression calculations and corrections, and appended bottle data in their final corrected form. Final CTD data is offered as a single compressed .zip file (i.e., yymm_CTDFinal.zip) containing files and folder structure for ASC-HDR, CSV-Plot, and metadata formats.

SBE & CalCOFI Data Formats

SBE formats

There are two types of SBE files that CalCOFI provides to users. There are six types of cast data created each cast by SeaBird's Seasave program during each CalCOFI station. ASC-HDR files are created by SBE Data Processing software module ASCII Out. This routine outputs the header portion (.hdr) and the data portion (.asc) of a processed converted data file (.cnv).
