CalCOFI Carbon -14 (14C) primary productivity experiments are conducted daily from local apparent noon (LAN) to civil twilight (CT). Three seawater samples from 6 depths (light-levels) are collected and innoculated with 14C. There are usually 15 daily incubation experiments per cruise and the resulting 14C-uptake measurements are reported separately in the cruise data report.  The tabulated data include pertinent, related hydrographic data along with primary productivity data. These data are available as: pdfs; Microsoft Access relational database - as a subset of the complete hydrographic database, separate table; primary productivity comma-delimited ascii file (csv).
