a Lagrangian sampling track starting at the BATS station (red point). Each black point represents a CTD-cast starting Oct. 12th, 2019, at 20:00 local time (GMT-3) and ending on Oct. 17th, 2019, at 08:00. b Schematic of a single day in the time series sampling profile. The surface (SRF) and base of the mixed layer (BML) were sampled every four hours, while the subsurface oxygen maximum (SOM) and deep chlorophyll maximum (DCM) were sampled every twelve hours. Panels c-f show CTD profiles interpolated over the entire time series (taken every four hours from the surface to 200 m depth) for c potential density (sigma-theta) (kg/m3) d Oxygen saturation (%) e Chlorophyll fluorescence (mg/m3) and f Beam attenuation (1/m); with the mixed layer depth (as defined by 0.125 difference in sigma-theta from 10 m) indicated in white. Depth names are designated at their approximate location in bold.
