This dataset consists of primary production measurements conducted during 24-h deckboard incubations using uptake of 13C-bicarbonate. Sampling occurred on NGA-LTER research cruises in the Gulf of Alaska and Prince William Sound during spring, summer and fall, starting in 2018. Stable isotope enrichment and associated POC determinations were done at the UC-Davis Stable Isotope Facility (SIF). For each cruise, there are two data sheets included: 1. calculation of depth specific primary productivity (based on 6 fractional light levels of the surface irradiance with reference to the PAR profile: 1, 0.5, 0.3, 0.1, 0.05 and 0.01), and 2. calculation of the integrated primary productivity. Depth specific and integrated chlorophyll data is included. Excel spreadsheets were converted to CSV files for preservation.
