Abstract

This dataset includes analyses from Niskin bottle samples collected on R/V Atlantis cruises AT32, AT34, AT38 and AT39-6 as part of the NASA NAAMES campaign (2015-2018). Reported are bacterial abundances and Dissolved Organic Carbon (DOC) measurements pre- and post-experiment. Remineralization experiments were used to examine the ability of natural assemblages of bacteria to utilize in situ DOM as well as different algal-derived substrates.
