Water isotope time series (March 2020 - March 2021) of samples collected at A. P. Møller Skolen, Kleine Breite, Schlei

Time series of stable isotopes (δ2H and δ18O) were analyzed in water samples collected near the A. P. Møller Skolen, Schleswig (Kleine Breite, Schlei), in biweekly to monthly intervals between March 2020 and March 2021. Water was sampled with a pipette from ca. 0.5 m below water surface and directly transferred into a measurement vial. Isotope analysis was conducted at IGB Berlin, using a Picarro L2130-i cavity ring-down spectrometer. Water chemical parameters were measured in-situ with a modular WTW 3440 multiparameter devices and regularly calibrated conductivity cells (MPP 930 IDS, TetraCon® 925-P). The data give information about the seasonal isotope amplitude at the sampled locations and about spatial variability along the transects.

Zooplankton Monitoring in Zingster Strom

<p>Monitoring of zooplankton communities was conducted in Zingster Strom on behalf of University of Rostock to characterize temporal dynamics and community composition within the coastal basin. The sampling strategy was designed to capture both quantitative and qualitative aspects of the zooplankton assemblage across monthly intervals. On a single day of each month, two complementary water samples were collected. A 1 L “full sample” was obtained to provide a quantitative representation of the ambient zooplankton community. In parallel, a 5 L “net sample” was collected and concentrated using a plankton net to enhance the detection of less abundant or larger-bodied organisms that may be underrepresented in smaller volumes. The monitored taxa comprise a broad spectrum of zooplankton groups, including copepods (e.g., Eurytemora affinis, Acartia tonsa, Temora), cladocerans (e.g., Bosmina, Daphnia-like taxa such as Diaphanosoma), rotifers (e.g., Keratella, Brachionus, Filinia, Polyarthra), and various meroplanktonic larvae such as polychaete larvae, as well as early life stages of mollusks (bivalves and gastropods). This taxonomic diversity reflects the transitional nature of the ecosystem, where marine and freshwater influences shape the zooplankton community. Samples were analyzed using optical microscopy, allowing identification based on morphological characteristics. The combination of full and net sampling approaches enables a more comprehensive assessment of both dominant and rare taxa, supporting robust ecological interpretation of seasonal patterns and environmental responses. These data contribute to long-term monitoring efforts aimed at understanding zooplankton dynamics in coastal systems and their role in trophic interactions and ecosystem functioning within Zingst Bay.</p>

Phytoplankton Monitoring in Zingster Strom

<p>Monitoring data were collected from Zingster Strom on behalf of University of Rostock to assess the composition and structure of planktonic microbial communities. The focus of this monitoring program was on phytoplankton, defined here as planktonic photoautotrophic microorganisms, including both eukaryotic microalgae and cyanobacteria, as well as closely associated protists. Water samples were collected directly from the basin using a 2 L water sampler to ensure representative capture of the planktonic community. In the laboratory, each sample was subsampled into two separate 2 mL aliquots to allow for complementary preservation and analysis approaches. One aliquot was fixed with Lugol's iodine solution, a standard preservative widely used in phytoplankton studies due to its effectiveness in maintaining cell morphology and enabling reliable identification and counting under light microscopy. The second aliquot was fixed with glutaraldehyde, which provides superior preservation of fine cellular structures and is particularly suitable for smaller or more delicate taxa. Microscopic examination was conducted using an optical microscope, allowing for taxonomic identification based on morphological characteristics. The monitored taxa encompassed a broad range of phytoplankton groups, including cyanobacteria (e.g., Microcystis, Anabaena), green algae (e.g., Scenedesmus, Pediastrum), diatoms (e.g., Navicula, Cyclotella), dinoflagellates (e.g., Ceratium, Peridinium), cryptophytes, euglenoids, and other protistan lineages. This diverse assemblage reflects the ecological complexity of transitional coastal systems such as Zingster Strom, where freshwater and marine influences intersect.</p>

Water isotope values in samples collected June 2019, March 2020 and July 2020 along estuarine systems at the Baltic Sea coast

Stable isotopes (δ2H and δ18O) were analyzed in water samples collected at 68 spots along the Schlei, the Zingster Bodden chain, and the Rügener and Greifswalder Boddens in June 2019, March 2020, and July 2021. Transect samples were taken at shores from 0.3 to 0.6 m below water surface, using a pipette, and directly transferred into measurement vials. Isotope analysis was conducted at IGB Berlin, using a Picarro L2130-i cavity ring-down spectrometer. Water chemical parameters were measured in-situ with a WTW multiparameter device (Multi 3630 IDS), equipped with a WTW TetraCon 925 electrical conductivity measuring cell. The data give information about the spatial isotope variability along the transects.

Water isotope time series (March 2020 - March 2021) of samples collected along the Zingster Bodden chain

Time series of stable isotopes (δ2H and δ18O) were analyzed in water samples collected at the Zingster Bodden chain in biweekly to monthly intervals between March 2020 and March 2021. Herefore, a Limnos sampler was used to obtain water from 0.5 to 1 m below surface. In the laboratory, a WTW 1970i conductivity meter and TetraCon 325 measuring cell were used to analyse electrical conductivity. Sub-samples were transferred into measurement vials before isotope analysis was conducted at IGB Berlin, using a Picarro L2130-i cavity ring-down spectrometer. Water chemical parameters were measured with regularly calibrated WTW multiparameter devices. The data give information about the seasonal isotope amplitude at the sampled locations and about spatial variability along the transects.

Water isotope values from estuarine systems along the German Baltic Sea coast

Stable isotopes (δ²H and δ¹⁸O) were analyzed in water samples collected at the German Baltic Sea Coast. Transect samples were taken in June 2019, March 2020, and July 2021 at 68 spots along the Schlei, the Zingster Bodden chain, and the Rügener and Greifswalder Boddens. Additionally, at selected spots time series were sampled in biweekly to monthly intervals between March 2020 and March 2021. At shores, water was sampled with a pipette from 0.3 to 0.6 m below water surface and directly transferred into a measurement vial. In deeper parts of the boddens a Limnos sampler was used to obtain water from 0.5 to 1 m below surface. Isotope analysis was conducted at IGB Berlin, using a Picarro L2130-i cavity ring-down spectrometer. The measurement uncertainty was quantified by error propagation, including the parameters a) uncertainties of lab standards; b) errors of standard calibration; c) average standard deviation of replicate measurements. Based on this, measurement uncertainty was estimated to account 0.16 ‰ for δ¹⁸O and 0.57 ‰ for δ²H. Water chemical parameters were measured with WTW measurement devices. The data give information about a) the seasonal isotope amplitude at the sampled locations; b) spatial variability along the transects, and c) the correlation between isotopes and water chemical parameters.

Akzeptanz des Stromnetzausbaus in Schleswig-Holstein, Akzeptanz der Offshore-Windenergienutzung

Ziel des Vorhabens ist die Erarbeitung von Handlungsempfehlungen für politische und andere Entscheidungsträger, um den Ausbau der Offshore-Windenergienutzung möglichst konfliktarm zu gestalten und zur Verbesserung der allgemeinen Akzeptanz der Windenergienutzung beizutragen. Für politische Entscheidungsträger wird darüber hinaus ein Strategieplan zur Akzeptanzsteigerung der Windenergienutzung entwickelt, im Sinne des Sozialen Marketing. Mögliche Auswirkungen von Offshore-Windfarmen auf die ansässige Bevölkerung, lokale Gewerbetreibende (z. B. Fischer, tourismusabhängige Geschäftsleute) und Touristen werden untersucht. Dazu werden im Abstand von zwei Jahren in vier Untersuchungsregionen Befragungen der drei genannten Gruppen durchgeführt. Einbezogen wird ebenfalls die Bewertung des Baus neuer Stromleitungstrassen. Die Befragungen werden durch trainierte Interviewer durchgeführt, eingesetzt wird ein standardisierter Fragebogen. Als Testregionen werden eine Nord- und Ostseeregion ausgewählt, in denen der Bau einer Offshore-Windfarm zeitnah erfolgt. In der Nordsee trifft dies für das Testfeld Alpha Ventus zu, in der Ostsee auf die Offshore-Windfarm Baltic I. Als Nordsee-Testregion werden entsprechend die Inseln Borkum und Norderney ausgewählt, als Ostsee-Testregion die Küstenregion Darß/Zingst. Als Vergleichsregionen werden die Region Büsum und die Ostseeküsten zwischen Kühlungsborn und Heiligendamm vorgeschlagen; eine Abstimmung erfolgt mit dem BMU.
