Description: This dataset contains measurements from LP20190603, collected aboard the R/V Ludwig Prandtl in June 2019 in the Elbe Estuary. In a transect cruise, geobiochemical parameters were measured starting in the North Sea (53.98°N 8.36°E) to the port of Oortkaten in the upstream Elbe Estuary (53.46°N 10.06°E). Sampling was conducted upstream against the outgoing tide to prevent tidal effects on the measurements. Water samples were taken approximately every 20 min. The discrete water samples were used to measure dissolved inorganic nutrient, nitrate stable isotope composition, suspended particulate matter (SPM) concentration, particulate carbon and nitrogen content of SPM and nitrogen stable isotope composition of SPM. An onboard membrane pump provided the on-line in situ FerryBox system. It continuously measured oxygen, salinity, and temperature during the cruise. A N2O analyzer coupled (Model 914-0022, Los Gatos Res. Inc., San Jose, CA, USA) with a seawater/gas equilibrator using off-axis cavity output spectroscopy continuously detected dry mole fraction of dissolved nitrous oxide along the estuary. Aim of the cruise was to study the interplay between eutrophication, in-stream nutrient regeneration and N2O emissions in a temperate Estuary.
