Figures 2 and 7 in the original published manuscript contained errors. Those are amended here.

Fig. 2

Hourly meteorological conditions (net heat flux, blue-red filling; wind speed, dashed black) derived from the COSMO model during the 3 microstructure and mooring samplings in 2018: a 24–26 April 2018, b 17–19 July 2018, and c 2–4 October 2018. Median profiles of d temperature, e buoyancy frequency and f chl-a fluorescence derived from the microstructure profiles in st1 for April 2018 (blue, SCAMP profiler), July 2018 (orange, VMP profiler) and October 2018 (green, VMP profiler). In a–c, microstructure profiles are indicated with black ticks, and the duration of mooring deployments is indicated with color filling. In c–f, the depth range of the P. rubescens thin layer, defined as the range where chl-a is larger than an e-folding fraction of the maximum value (chl-a > max(chl-a)/e), is indicated by filled rectangles for July (orange) and October (green). Individual profiles for chl-a are shown in f as semi-transparent lines. Individual profiles were projected onto isothermal coordinates to remove the effect of internal wave motions (color figure online)

Fig. 7

Microstructure measurements collected with a microCTD profiler during the dedicated nighttime sampling on 24–25 September 2019 at st0. a Hourly surface net heat flux (colors) and wind speed (black) derived from COSMO model, b TKE dissipation rate ($\varepsilon$), c Thorpe scale ($L_T$), and d heat diffusivity ($K_T$). Temperature contours every 2 $^{\circ }$C and hourly values of the Monin–Obukhov length-scale ($L_{MO}$, black line with dots) are plotted in b–d. Upward and downward looking triangles indicate ascending and descending profiling, respectively. The color scale of the triangles represents the sampling time. Surface mixing-layer depth (defined as $L_T>1$ m) is indicated with horizontal black markers in c. Time in the x-axis UTC time (local time was UTC+2) (color figure online)
