Depth profiles (black lines) of (a) pH values as obtained by the pH sensor, (b) nitrate concentration as obtained by the SUNA UV-spectrometer, (c) backscatter, (d) chlorophyll-a, and (e) FDOM (fluorescent dissolved organic matter) as obtained by the ECO-triplet fluorometer. Blue lines represent the smoothed data as obtained by applying a running mean with a window size of 10. The data was collected on 22/02/2020. The red line in (e) shows a FDOM profile obtained close to Polarstern using a large CTD rosette on 21/02/202038,93 (Fig. 3a).
