  • Changed value of field methodDescrioption to **Ice core collection ** - Field Measurement The 1-cm or 5-cm bottom section of several ice cores was collected, pooled immediately in a dark isothermal container and melted in 0.2-m filtered seawater (FSW) at a ratio of 3:1 (three parts FSW, one part ice core volume) in the dark over 24 h to reduce osmotic stress. **Water collection ** - Field Measurement Water samples for the measurement of chlorophyll a concentration were collected from the optical depths at 100 (i.e. sea surface), 30, 15, 5, 1, and 0.2% of surface irradiance with 12-L Niskin bottles (Rosette), and from the ice-water interface, melt ponds and rivers with a pump. **Additional Comments** - Sea ice sampling was performed with a 9-cm core barrel (Mark II, Kovacs Enterprises) on snow-covered and white ice areas. No sea-ice cores were collected in melt ponds. - The rosette on the research vessel CCGS Amundsen was equipped with 12-L Niskin bottles. in Chlorophyll a concentration in ice and water

  • Changed value of field analyticalMethodName to Measurement of chlorophyll a concentration (Lab measurement) in Chlorophyll a concentration in ice and water
