    Sediment phaeopigment concentrations from the Laptev Sea (Arctic Ocean) during Polarstern expedition ARK-XXVII/3 (PS80) from August-September 2012 (2021)

    Details

    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 and total organic carbon measured during POLARSTERN cruise PS94 (TransArcII) to the Barents Sea and central Arctic (2019)

    Description: Chlorophyll pigments: Subsamples of the top first cm of sediment were obtained using cut-off plastic syringes. Samples for chlorophyll pigment analyses were stored dark and frozen at -20°C until further analyses in the home laboratory. Chlorophyll pigments were extracted as described in Boetius et al. (1998, https://doi.org/10.1016/S0967-0637(97)00052-6). Briefly, pigments were extracted in 90% acetone, after addition of glass beads and grinding in a cell mill. Extracts were centrifuged and concentrations of chlorophyll a and phaeopigments (after acidification with HCl) were determined with a Turner Trilogy fluorometer. The sum of chlorophyll a and phaeopigments is expressed as chloroplast pigment equivalents (CPE). The proportion of chlorophyll a from CPE (% chla) is an indicator of the freshness of phytodetritus. Total organic carbon: Subsamples of the top first cm of sediment were also obtained using cut-off plastic syringes. Samples were stored frozen at -20°C until further analyses in the home laboratory. The total carbon content of sediment samples was determined by combustion and gas chromatography with a Carlo Erba NA-1500 CNS elemental analyzer. An aliquot of the sample was acidified to remove the fraction of inorganic carbon and to determine the total amount of organic carbon.
