I. Directly measured parameter data (depth, chlorophyll-a, dissolved oxygen, SPM, extinction coefficient, salinity, temperature, nutrients) are available for download in csv files:
Scientific Data article with detailed data descriptions
II. Calculated parameters (chlorophyll ratio, oxygen % saturation, Sigma-t) are available upon request. These variables are defined on our data description page.

Metadata are included in the data products linked above and the Scientific Data article. Also please see the data descriptions, glossary, and general overview of the sampling program.
2014-2018 Si were corrected 0-10% October 2019.
Si data are not available for 2011 - Feb 2014
NO2 data are not available for 2005 - 2011
Light attenuation data are not available for 2002 - 2006
Sigma-t was not calculated prior to November 1987
CTD sampling began Nov 1987, since this time discrete data are collected and listed at 2m and/or bottom depth, and light extinction coefficient is listed on the 1m line, or the surface depth if not 1m. Prior to Nov 1987 discrete parameters were collected at variable depths (commonly 0.5m, 1m, and 2m) and light extinction coefficient is list at 0.5m, 1m or 2m.
Time of day values for cruise data sampled 1981 through 1987 are accurate within +/- 30 minutes
