REIN-project: Air quality data from gas and particle sensors at the river Rhine in Koblenz, Germany

This dataset provides data from various air quality sensors at a floating platform of the Federal Institute of Hydrology at the river bank of the Rhine in Koblenz, Germany. The data was collected as part of the mFUND project "REIN" which investigated the suitability of low-cost sensors for the determination of ship emissions with high spatial and temporal resolution. Measurement data involves various pollutants, including nitrogen oxides (NO, NO2), carbon dioxde (CO2) and particulate matter (particle number concentration, mass concentration, size distribution, ultrafine particles, black carbon concentration). Averaged data is provided at 1 minute and 1 hour temporal resolution and covers both low-cost and standard instruments. The dataset is related to the publication "Applicability of compact low- and mid-cost sensors to monitor air pollutant emissions from in-land ships".

Gewässerbauwerke Hamburg

Bauwerke in und an Gewässern der FHH Hamburg verfügt als wassergeprägte Metropole über ein dichtes und vielfältiges System von Gewässern, das von Tideflüssen wie der Elbe über Nebenflüsse, Kanäle bis hin zu kleineren Bächen und Gräben reicht. Zur Steuerung, Nutzung und Sicherung dieser Gewässer kommt eine Vielzahl technischer Anlagen – die sogenannten Gewässerbauwerke – zum Einsatz. Zu den wichtigsten Gewässerbauwerken in Hamburg zählen unter anderem Schleusen, Wehre, Sperrwerke, Pumpwerke, Fischaufstiegsanlagen sowie Durchlässe und Stauanlagen. Diese Bauwerke erfüllen unterschiedliche Funktionen, die eng miteinander verzahnt sind: Hochwasserschutz: Insbesondere entlang der Elbe und ihrer Nebenflüsse sichern Sperrwerke und Deichanlagen die Stadt vor Sturmfluten und steigenden Wasserständen. Wasserstandsregelung: Wehre und Schleusen stabilisieren Wasserstände in Binnengewässern und Kanalsystemen und ermöglichen eine kontrollierte Ableitung von Niederschlagswasser. Entwässerung und Regenwassermanagement: Pumpwerke und steuerbare Bauwerke gewährleisten den Abfluss von Oberflächenwasser, insbesondere in tiefer liegenden Stadtteilen. Schifffahrt und Nutzung: Schleusen in Fleeten und Kanälen ermöglichen die Durchgängigkeit für Boote und unterstützen die historische sowie aktuelle Nutzung der Wasserwege. Ökologische Funktionen: Moderne Bauwerke integrieren zunehmend Maßnahmen zur ökologischen Durchgängigkeit, etwa durch Fischaufstiegsanlagen oder naturnahe Umgestaltungen. Hamburg steht dabei vor besonderen Herausforderungen: Neben dem Einfluss der Gezeiten erfordern Klimawandel, Starkregenereignisse und steigende Meeresspiegel eine kontinuierliche Anpassung und Modernisierung der Gewässerinfrastruktur. Die Planung, der Betrieb und die Unterhaltung der Gewässerbauwerke erfolgen im Rahmen eines integrierten Gewässermanagements. Ziel ist es, technische Sicherheit, urbane Nutzung und ökologische Anforderungen in Einklang zu bringen und so die nachhaltige Entwicklung der Stadtlandschaft zu gewährleisten.

Measurements and simulation of inland ship emissions at the Dortmund-Ems canal, Germany

This dataset provides air quality data from parallel on-board and onshore measurements of ship exhaust emissions as well as data from a simulation (with the large-eddy model PALM) at the Dortmund-Ems canal in Germany. Measurement data involves various pollutants, including nitrogen oxides (NO, NO2), carbon dioxde (CO2) and particulate matter (particle number concentration, mass concentration, size distribution, ultrafine particles, black carbon concentration). The dataset is related to the publication "Connecting inland ship emissions from on-board sampling, onshore measurements and large-eddy simulations".

Master tracks in different resolutions of ALKOR cruise AL650, Kiel - Kiel, 2026-04-15 - 2026-04-17

Raw data acquired by position sensors on board RV Alkor during expedition AL650 were processed to receive a validated master track which can be used as reference of further expedition data. During AL650 data from the Seapath 330 system, the Furuno GP-170 receiver and the SAAB R6 system were used to calculate the mastertrack. Data were downloaded from DAVIS SHIP data base (https://dship.o2a-data.de/) with a resolution of 1 sec. Processing and evaluation of the data is outlined in the data processing report. Processed data are provided as a master track with 1 sec resolution derived from the position sensors' data selected by priority and a generalized track with a reduced set of the most significant positions of the master track.

Distribution and concentration of nutrients, carbon compounds and methane in water samples in the southern German Bight (North Sea) in September 2024 during the MOSES Sternfahrt 12

The 12th Sternfahrt of the ElbeXtreme and MOSES projects took place in 2024 from September 02 to 13, within the area of the German Bight (North Sea). Its objective was to get a more systematic grid of sampling data by spatially integrated onboard sensors. Therefore, the MOSES-laboratory container was installed again. Water samples were taken from the surface with a rosette or via Niskin bottles. The first part of the cruise was conducted by the research vessel (RV) Ludwig Prandtl, starting on the 2nd of September on Heligoland. From there, the crew navigated towards Cuxhaven covering some stations from previous MOSES cruises. For the next days, the ship followed a rectangular track, shifting northward each day, heading towards Heligoland again. Due to strong winds, the sampling stations were reduced to three on the last day. On Heligoland the RV Mya II took over the laboratory container and other sampling equipment for the second part of the cruise. Persistent strong winds delayed the start of the cruise until September 11. Since most of the planned stations were already covered from the RV Ludwig Prandtl, the crew decided to expand the sampling area using a more systematic zig-zag line. With the return of Mya II in the afternoon of the 13th September 2024, the campaign was successfully finished.

Whale sightings during POLARSTERN cruise PS109 (ARK-XXXI/4)

Data on whale distribution and abundance in the polar oceans is rather sparse, as implementing the standard surveying method, line-transect surveys, is challenging and costly. To overcome this problem, we initiated a program to electronically log all opportunistic cetacean sightings during all Polarstern expeditions through the nautical officer on watch. Opportunistic (visual) sightings by naked eye were logged during Polarstern Cruise PS109 (Tromsø – Bremerhaven) by the nautical officer on duty using a customized Software package (WALOG, WhAleLOGger) installed on a touch screen laptop located on the ship's bridge. Species were identified by naked eye or handheld binoculars (7x50) to the lowest possible taxonomical level and assigned a "certainty" level of identification. The number of animals were counted if possible or estimated for larger groups. Whenever identification to species level was not possible, the next identifiable taxonomical category was assigned. Information on sighting position, date and time are automatically transferred from the ship's DAVIS-Ship System (https://dship.awi.de/) to the WALOG software at the time of logging. Photographs were taken, if possible, for retrospective analysis. All data of acquired sightings were retrospectively validated by a marine biologist and converted to a standard format. To this end, plausibility of sighting time, location, standardization of species names, eventual comments added at the time of sighting, as well as additional information such as photographs (if available) were checked either to verify or improve species identification. Datasets are used in species distribution modelling and to inform interested parties about occurrences.
