Description

Photosynthetic data on water collected by CTD and measured using fast repetition rate fluorometry.

Methods & Sampling

Photosynthetic parameters were measured using fast repetition rate fluorometry on whole seawater collected by CTD. See reference below for details on data analysis.

Data Processing Description

Photosynthetic parameters were corrected for background fluorescence by measuring 0.2 µm filtered seawater from 1-2 depths. Fo and Fm of background samples were subtracted from sample Fo and Fm and corrected values were used to calculate Fv/Fm, where Fv=Fm-Fo (Kolber et al. 1998)

DMO Notes:
-File was resubmitted by PI after some consultation with several columns and rows removed
-Column names were changed to meet BCO-DMO standards
- Some spaces were removed from cell contents
- cruise_id and ISO_DateTime_UTC column were added
