Abstract

Bulk and cell-specific CO2 fixation and PO4 uptake from Atlantic Explorer cruise AE1524 (BATS validation cruise BV50), September 2015. Phosphate uptake rates were measured in Prochlorococcus, Synechococcus, pigmented eukaryotes, and unpigmented eukaryotes. Also reported are CO2 fixation rate by Prochlorococcus, Synechococcus, and pigmented eukaryotes.

Cite Dataset

Bulk and cell-specific CO2 fixation and PO4 uptake from Atlantic Explorer cruise AE1524 (BATS validation cruise BV50), September 2015 in the North Atlantic subtropical gyre (September 2015), along a transect from Bermuda to Puerto Rico extending from 33°N to 22°N. Phosphate uptake rates were measured in Prochlorococcus, Synechococcus, pigmented eukaryotes, and unpigmented eukaryotes. Also reported are CO2 fixation rate by Prochlorococcus, Synechococcus, and pigmented eukaryotes. These data were published by Duhamel et al (2019), Table 3.
