Bacterial production, community respiration and primary production rates measured from water bottle samples during METEOR cruise M160


This dataset includes measured and calculated data over the epi-mesopelagic layer (0-450 m depth) of 29 stations with 4 stations within a cyclonic eddy nearby Brava island, 5 stations within a cyclonic eddy nearby Sal island, and one station within an anticyclonic eddy around the Cabo Verde islands in the eastern Tropical North Atlantic during the M160 cruise on the RV Meteor from November 22nd to December 20th, 2019. Bacterial biomass production rates were measured through the incorporation of labelled leucine (3H) using the microcentrifuge method (Kirchman et al., 1985,; Smith and Azam, 1992). Extracellular release rates, dissolved-, particulate- and total- primary production rates were determined from 14C incorporation according to Nielsen (1952, and Gargas (1975). Community respiration was measured from optodes based method (Wikner et al., 2013;

Bacterial biomass production and community respirations rates were measured from incubation at 13°C and primary production rates from incubations at 22°C.
