Biological sampling was performed using the AUV Clio and additional parameters were collected via CTD rosette at each station. The surface transect is shown overlaying sea surface temperature and satellite-derived chlorophyll a concentrations between June 19–28th 2019, obtained from NASA MODIS. Continuous beam transmission (turbidity), temperature, and dissolved oxygen measurements were obtained via the ship CTD, and dissolved nutrients were measured from discrete samples from the top 1500 m of the water column (see Supplementary Fig. 1 for full-depth temperature and oxygen sections). Note that surface nitrate+nitrite concentrations dropped below the detection limit of 0.06 μM in surface waters of St. 3, 6, and 7, and silicate concentrations were below the detection limit of 0.19 μM in the top 100 m throughout the section (Supplementary Data 1). Seawater samples collected by Clio for metaproteomics and metatranscriptomics were obtained from the depths shown in the bottom section plots.
