Method P.193 right column 2nd paragraph: "Cells were collected onto GF/F filters and immediately transferred to 5 ml 90% acetone for Chla extraction (18–24 h at −20°C). Chla concentration was determined with a fluorometer (Turner Designs 10‐AU, Sunnyvale, CA, USA) by measuring nonacidified and acidified fluorescence (Welschmeyer, 1994)."
Comments P.195 left column 3rd paragraph: "With the increase in light intensity and ice retreat in early November, phytoplankton biomass, dominated by diatoms (microscopically identified species: e.g. Corethron spp., Thalassiosira spp., Fragilariopsis spp. and Eucampia spp.) with diameters of c. 20 μm, increased throughout November to a maximum Chla concentration of c. 45 μg Chla/l by early December (Fig. 1a)."
