| Summary: | These are data obtained and measured for the Cherkasheva et al (submitted in 2023) study during RV "Kronprinz Haakon" 2021 Fram Strait cruise and RV "Maria S Merian" 2022 Greenland Fjords cruise. This dataset has 13 points for August 2021-2022. The Gross Primary Production estimation from optode O2 measurements was derived with the method adapted from Campbell et al (2016), and also described in section 6 of IOCCG Protocol Series (2022). The incubation bottles were overfilled with the seawater sample to prevent the formation of a headspace during closure of the glass stopper, and placed into containers with seawater under continuous illumination and mixing. The incubation temperature in the cold room was set to +4°C, which was representative of the average in situ seawater conditions. After the measurements were done, the values were averaged for duplicates in case of 2021 cruise and triplicates in case of 2022 cruise.
