Description

Nutrients, pigments, bottle data, and experimental and survey biogeochemical data from cruise OC1504A. "Silica production rates were characterized by delivering incremental increases in silicic acid (Si) along with a radioactive isotope of silicon (32Si). This extremely sensitive assay can determine the maximum production rates of the community being studied and the degree that its growth is being limited by lack of Si." (from cruise blog)

BCO-DMO Processing Notes:
- system added negative to the longitude because West;
- modified parameter names to conform with BCO-DMO naming conventions;
- replaced ~ with 'nd' to indicate 'no data';
