    Description: Sampling was conducted with a TV-guided multiple corer (MUC), in order to retrieve undisturbed sediment cores. Upon retrieval of the MUC, the overlying water was carefully removed from each core and the core was cut into the following sediment horizons using a steel plate and a custom-made plastic ring: 0-1 cm, 1-5 cm, 5-10 cm. At each station, sediment samples from three replicate cores were pooled and transferred to a cooling container (0°C), where subsamples for chloroplastic pigment analyses were taken and processed directly on board. Chloroplastic pigments were extracted from 1 ml sediment with 3 x 8 ml acetone (90%), including the addition of glass beads and grinding of the samples in a cell mill according to Boetius & Damm 1998 (doi:10.1016/S0967-0637(97)00052-6). Samples were centrifuged and chlorophyll a and phaeopigment (after addition of 250 µl 25% HCl) concentrations were determined in the superanatant by fluorometric measurement with a Turner Trilogy fluorometer. Measurements were performed in triplicate for each sample.

    Chlorophyll pigments of the central Arctic Ocean during POLARSTERN cruise ARK-XXVII/3 from August-September 2012 (2015)

    Description: During the RV Polarstern cruise ARK-XXVII/3 to the Arctic Ocean in summer 2012, when sea ice declined to a record minimum bottom, sediments were collected with a TV-guided multicorer at stations in the Nansen and Amundsen basin. Chlorophyll a and phaeopigments were extracted from sediments with acetone using three replicates per station. The concentrations in the acidified supernatants were measured with a Turner Trilogy fluorometer (Boetius and Damm, 1998). The sum of chlorophyll a and phaeopigments is expressed as chloroplast pigment equivalents (CPE) (Thiel, 1982).
