The original version of this Article contained errors in Figure 3, where color scale bars with the concentration of Chlorophyll a (μg/l Chl a) were omitted. The original Figure 3 and accompanying legend appear below.

Fig. 3
figure 3

Spatial and temporal variation in total phytoplankton biomass (Chl a, μg/l) in the surface and bottom layers for each sampling period. 26 April 2022: (a) surface and (f) bottom; 15 July (1) 2022: (b) surface and (g) bottom; 16 July (2) 2022: (c) surface and (h) bottom; January 18, 2023: (d) surface and (i) bottom; 25 May 2023: (e) surface and (j) bottom. Map data: Google, CNES/Airbus. Software used: Google Earth Pro and Adobe Photoshop. The interpolation of values was performed according to weighted-average gridding by Ocean Data View (odv.5.7.1—http://odv.awi.de).

Additionally, Figure S1 from in the Supplementary Information stated incorrect sampling dates from the Po River flooding. The original Figure S1 and accompanying legend appear below.

Hydrometric level of the Po River over 24 h for each sampling date. Values are reported as meters below the attention level (0).

The original Article and accompanying Supplementary Information file have been corrected.
