    Prokaryotic cell abundance and biomass measured during Maria S. Merian cruise MSM29 and Polarstern cruise PS85 to the Fram Strait (2019)
    PANGAEA
    Details
    Publication Date: 2024-07-01
    Description: Prokaryotic cell abundances and biomass were determined in deep-sea sediment samples collected at the deep-sea LTER HAUSGARTEN, located in the Fram Strait. Sampling was performed during two cruises, i.e. RV Maria S. Merian MSM 29 in summer 2013 (23 June-12 July) and RV Polarstern PS85 in summer 2014 (6 June-3 July). Undisturbed sediment cores were collected with a TV-guided multicorer. Prokaryotic cell abundances were determined using acridine orange direct counts, following the procedure described in (Hoffmann et al., 2017; doi:10.3389/fmicb.2017.00266). For each sample two replicate filters were counted. Cell volumes were determined using a stage micrometer and converted to biomass using a conversion factor of 3 x 10^-13 g C /µm³ (Børsheim, K. Y., Bratbak, G., and Heldal, M. (1990). Enumeration and biomass estimation of planktonic bacteria and viruses by transmission electron microscopy. Applied and Environmental Microbiology 56, 352-356).

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

    Details
    Publication Date: 2024-07-01
    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.
