A global database of dissolved organic matter (DOM) concentration measurements in coastal waters (CoastDOM v.1)

This global database (CoastDOM v.1) contains both previously published and unpublished measurements of Dissolved organic carbon (DOC), nitrogen (DON) and phosphorus (DOP) in coastal waters. The dataset also contains hydrographic data such as temperature and salinity and, to the extent possible, other biogeochemical variables (e.g., Chlorophyll-a, inorganic nutrients) and the inorganic carbon system (e.g., dissolved inorganic carbon and total alkalinity). The data included were collected from 1978 to 2022 and consist of 62339 data points for DOC, 20360 for DON and 13440 for DOP.

Greenhouse gases in the River Elbe, 2020-2024

Measurements of dissovled greenhouse gases (GHG) being CO2, CH4 and N2O were performed from 2020 until 2024. Water samples were taken from bridges at tow locations at the river Elbe; Magdeburg and Wittenberge. For CO2, CH4, and N2O analysis, 30 mL water samples were collected in 60 mL plastic syringes. A headspace of 30 mL ambient air was added. After vigorously shaking for one minute the headspace was transferred to pre-evacuated 12 mL exetainers (Labco, UK) and water temperature in the syringe (=equilibration temperature) was measured. Ambient air samples for headspace correction were taken on each occasion. These samples were analysed in the laboratory with gaschromatography (Koschorreck et al 2021). Water physicochemical parameter (temperature, O2, pH) were measured immediately with a WTW-probe. Water-chemical variables were measured using standard methods as described in Kamjunke et al. (2021).

Water chemistry of Lagrangian samplings of Inland Elbe 2024 (MOSES Hydrological Extremes)

Within the framework of MOSES (Modular Observation Solutions for Earth Systems) and ElbeXtreme, we performed three longitudinal sampling campaigns in the Elbe catchment in 2024. The campaigns covered the German freshwater part, the tidal Elbe river, and the German Bight. Here we present the results of the freshwater river where the sampling was conducted in a Langrangian way according to flow velocity. Physico-chemical and biological parameters were measured along the Elbe from bridges between Bad Schandau (km 12, Czech-German border) and Lauenburg (km 570, close to Hamburg). A particular scientific focus was on (1) nutrients and eutrophication, (2) composition of dissolved organic matter measured by high-resolution mass spectrometry, (3) greenhouse gas measurements, and (4) micropollutants. This was done during a winter flood event in January, a summer drought in July, and a second smaller flood in September 2024.
