    Dissolved methane concentration variability along freshwater-sea continuum at Heligoland, Southern North Sea, 2021 (2023)
    PANGAEA
    Details
    Publication Date: 2023-10-19
    Description: The dataset is about temporal variability of dissolved methane along the freshwater-sea continuum in northern Germany. Sensors were installed at fixed stations at in total three sites at different water depths. This dataset is from the station in Heligoland (54.1833 N, 7.8667 E) at about 9-12m depth (depending on the tide). The data was obtained between 27 April and 28 October in high frequency measurements (1 min) with a methane sensor from Kongsberg (4H Jena model CONTROS HydroC CH4,). Methane concentrations were calculated according to manufacturer's instructions, based on temperature and salinity values from UW-node Heligoland (Fischer, Philipp; Happel, Lea; Brand, Markus; Eickelmann, Laura; Lienkämper, Miriam; Bussmann, Ingeborg; Anselm, Norbert; Brix, Holger (2022): Hydrographical time series data of Helgoland, Southern North Sea, 2021. PANGAEA, https://doi.org/10.1594/PANGAEA.950173). A gap in the salinity data was replaced with the median value of the observed time span (31.66). For the quality control of the data a local range of 0.1 – 1000 nmol/L was set, a technical range for the pump power 2 – 8. Watt, a spike and gradient value of 1. For a more detailed description see the article cited in References.

    Carbon compounds, nutrients and methane from water samples from MOSES project's cruise Sternfahrt 8, September 2021 (2023)
    PANGAEA
    Details
    Publication Date: 2024-04-04
    Description: The cruise Sternfahrt_8 was a continuation of the previous Sternfahrten (1-7). This time the aim was to assess not only the spatial variability but also the temporal variance of chemical, physical and greenhouse gases in the German Bight (North Sea). Therefore, three ships with different tracks repeated the same track with the same stations for four days (GPS-Positions see metadata). One Ship (Uthörn) covered the western part of our study area, the second ship (Littorina) covered the northern part (Büsum – Heligoland) and the third ship (Ludwig Prandtl) was supposed to take the middle part (Cuxhaven – Heligoland), but due to vandalism damage in the beginning of the cruise this ship was not able to participate in the cruise. Apart from continuously measurements six CTD stations were run each day delivering discrete water samples for DIC, TA, DOC, methane, nutrients and explosive metals. This dataset contains the results from the latter water samples. For more detailed information about the MOSEShx campaign and the cruise Sternfahrt_8 respectively see article cited in references.
