Our study took place in under-ice seawater of Young Sound-Tyrolerfjord in Northeast Greenland between 30 May and 23 June, 2014. Samples for chlorophyll-a (Chl-a) were collected at depths of 0 and 1 m in under-ice seawater. To determine the Chl-a concentration, seawater was filtered using Whatman GF/C glass-fiber filters. Filters were then stored frozen in aluminum foil until measurement at the home laboratory in Aarhus University, Denmark where filters were extracted in 10 mL acetone at 4 °C for 16 h. The Chl-a concentrations were subsequently determined using a Turner Design TD700 fluorometer.
