    Description: On 25 and 26 of June in 2019 transects between Cuxhaven and Bremerhaven towards Helgoland were performed with the RV Prandtl and Uthörn. Basic hydrographic parameters were measured with two ferry boxes using the ships water supply. Data were saved once per minute. Dissolved methane was determined continuously. We used a degassing unit which was using surface water from the ship's water supply in an overflowing bucket. The gas mixture was subsequently analyzed with a Greenhouse Gas Analyzer from LosGatos. Conversion to methane concentration was performed with water samples, from which the methane content was determined with gas chromatography.

    Description: On the MOSES cruise Sternfahrt_1 water samples were taken on 8 stations. Samples were exchanged between the institutes Alfred-Wegener-Institut Zentrum für Polar- und Meeresforschung (AWI), Helmholtz Centre for Ocean Research Kiel (Geomar) and Helmholtz-Zentrum Geesthacht Centre for Materials and Coastal Research (HZG) for later comparison of the nutrient data.

    Description: During Stern_3 single water samples were taken either from a rosette (vertical) or from on the way systems. For the on the way systems a time off-set was calculated and subtracted from the original time. The aim of the sampling was mainly to counter-check with different sensors. More details can be found in the expedition report (Fahrtbericht Moses Sternfahrten). For methane concentrations, water was transferred to glass bottles (120 ml) and stored cold (4°).

    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.

    Description: The MOSES Elbe 2023 experiment aims at following a water mass from the spring of the Elbe River in the Czech Republic, through the freshwater and tidal sections of the river, into the North Sea, where three ships (Mya II, Littorina, and Ludwig Prandtl) were used covering the marine environment in the German Bight (Sternfahrt 10). In order to follow the water mass from the Elbe estuary numerical simulations were performed to determine the likelihood of a variety of starting points for a drifter release experiment. At the first morning of the cruise model forecasts were used to determine the exact locations where drifters were to be released. The drifters were initially released in groups of three drifters and then supplemented at a later point of time. During the following two and a half weeks, the current drifter positions were revisited from the ships involved to take water samples.
