Biotopkartierung (SH4) Marine Daten

Der vorliegende Geodatensatz umfasst alle bis zum angegebenen Stand kartierten bzw. abgegrenzten FFH-Lebensraumtypen (= LRT) der Meeresgewässer und Gezeitenzonen (1110, 1130. 1140, 1160, 1170) ohne die LRT 1110 und 1170 der Ostsee, für die ein separater Datensatz bereitgestellt wird. Die Abgernzungen in der Nordsee wurden durch die zuständige Nationalparkverwaltung durchgeführt bzw. mit ihr abgestimmt und spiegeln den aktuellen Kenntnisstand wieder. Die Abgrenzungen in der Ostsee wurden in Abstimmung mit der Abteilung Wasserwirtschaft, Dezernat Küstengewässer z. T. anhand von Tiefenlinien und Exposition durchgeführt. Die Abgrenzungen erfolgten i. d. R. nicht durch tatsächliche Kartierung im klassischen Sinne durch Inaugenscheinnahme, sondern durch Detektion (z.B. Sonar) und dient in erster Linie der Abgrenzung LRT zur Erfüllung europarechtlicher Berichtspflichten. Die Anspache der z.T. flächenidentischen gesetzlichen Biotope sowie die Bewertung des Erhaltungsgrades der LRT wird in diesem Datensatz nicht abgebildet. Weitergehende Erläuterung zum Begriff "Wertbiotop": Im Rahmen der BK gehören zu den Wertbiotopen grundsätzlich alle Flächen, die entweder als gesetzlich geschützte Biotope gemäß § 30 BNatSchG i. V. m. § 21 LNatSchG gelten und/oder als Lebensraumtyp (LRT) gemäß Anhang I der FFH-Richtlinie (92/43/EWG, 21.05.1992) anzusprechen sind. Hinsichtlich des gesetzlichen Biotopschutzes ist der Stand nach der Novellierung des Landesnaturschutzgesetzes (LNatSchG) in 2016 (Veröffentlichung in dem GVO Nr. 7 vom 23.06.2016, Seite 162) berücksichtigt und schließt das „arten-und strukturreiche Dauergrünland“ mit ein. Auch die Änderungen aufgrund des § 21 Absatz 7 des Landesnaturschutzgesetzes (LNatSchG), zuletzt geändert durch Verordnung vom 27. März 2019 (GVOBl. Schl.-H. S. 85), sind berücksichtigt sowie - soweit bereits erhoben bzw. in Schleswig-Holstein überhaupt v.h. - auch die seit dem 1. März 2022 gem. § 30 Absatz 1 Nummer 7 BNatSchG neu erfassten gesetzlich geschützten Biotope. Zu den Wertbiotopen gehören im vorliegenden Geodatensatz sämtliche Flächen/ Geometrien, die in den Tabellenspalten „BTSCHUTZ_1“ und/oder „BTSCHUTZ_2“ der Attributtabelle einen Eintrag einer Biotopverordnungsnummer (VO) oder die in den Tabellenspalten „LRT_TYP_1“ und/oder „LRT_TYP_2“ einen Eintrag eines Natura 2000- bzw. EU-LRT-Codes aufweisen. Nachrichtlich weist das LfU darauf hin, dass der Schutz des § 30 BNatSchG i. V. m. § 21 LNatSchG aktiviert wird, wenn und sobald eine Fläche die charakteristischen Merkmale eines gesetzlich geschützten Biotopes erfüllt. Der in § 30 Abs. 7 thematisierten Registrierung, die sich nach Landesrecht richtet und zumeist in Biotopkartierungen, Listen oder Biotopverzeichnissen ihren Niederschlag findet, kommt daher eine lediglich deklaratorische Bedeutung zu. D.h. nicht erst durch die Kartierung bzw. Erfassung und Registrierung werden Flächen zum geschützten Biotop, sondern der Charakter als gesetzlich geschütztes Biotop ergibt sich unmittelbar aus dem Gesetz. Bei Fragen und in Zweifelsfällen ist mit der fachlich zuständigen Person im LfU Rücksprache zu halten. Hinweis: Daten der maritimen LRT 1110 und 1170 in der Ostsee, befinden sich in dem separaten Geodatensatz "Maritim_Daten_Ostsee_LRT_1110_und_1170".

Dissolved and particulate trace metal and rare earth element (REE) concentrations during a mesocosm based phytoplankton bloom simulating intertidal coastal conditions

We analyzed concentrations of dissolved and particulate trace metals, including iron (Fe), manganese (Mn), vanadium (V), molybdenum (Mo), thallium (Tl), and rare earth elements (REE), during a mesocosm-based phytoplankton summer bloom mimicking the intertidal zone of the southern North Sea (Jade Bay). The studies aimed to identify key drivers controlling their biogeochemical cycling in dynamic, high-productivity coastal environments. Our results highlight the tidally influenced coastal zone as a critical interface that alters the behavior of supposedly conservative elements such as Mo and Tl (Mori et al., 2021) as well as natural and anthropogenic REE (incl., lanthanum, samarium, and gadolinium) (Mori et al., 2026). Trace metal concentrations and shale-normalized REE patterns, determined by quadrupole inductively coupled plasma–mass spectrometry (ICP-MS) and inductively coupled plasma–optical emission spectrometry (ICP-OES), were combined with biogeochemical bulk parameters and pigment-based assessments of phytoplankton growth and community composition (Mustaffa et al., 2020). Trace metal and REE cycling were evaluated in relation to phytoplankton dynamics, particulate organic matter composition (C, N, P), dissolved organic carbon, total dissolved nitrogen, and macronutrient concentrations (nitrate, ammonium, silicate, and inorganic phosphate). The dataset was obtained during a Planktotron-based mesocosm experiment conducted within the framework of the Coastal Ocean Darkening project (Mustaffa et al., 2020).

Behavioral, metabolomic, heat shock protein 70, and catalase responses of Littorina littorea to acute experimental warming in Helgoland (North Sea, Germany) during November 2023 and June 2024

Adult Littorina littorea were collected from the intertidal zone of Helgoland (North Sea, Germany; 54°11′ N, 7°53′ E) during November 2023 and June 2024 to investigate physiological and behavioral responses to acute warming. After collection, the organisms were transported to the Alfred Wegener Institute in Bremerhaven, Germany, and acclimated for two weeks to season-specific temperatures representative of winter (10 °C) and summer (16 °C) in aquarium systems containing filtered, recirculating, and continuously aerated seawater at a salinity of 33. Animals were fed Fucus vesiculosus ad libitum throughout the acclimation period. Following acclimation, individuals were exposed to a continuous warming ramp from the respective seasonal acclimation temperature to 34 °C at a rate of 1.5 °C h⁻¹. Samples were collected at predefined temperature intervals between 10 and 34 °C for winter-acclimated animals and between 16 and 34 °C for summer-acclimated animals.The dataset contains behavioral, metabolomic, and biochemical measurements obtained from snails at the respective experimental temperatures. Behavioral observations include the time required for antenna extension and the initiation of locomotion. Metabolomic data were obtained from whole-body soft-tissue extracts using proton nuclear magnetic resonance spectroscopy using the ultra-shielded vertical 9.4 T NMR spectrometer (Advance III HD 400 WB, Bruker-BioSpin GmbH, Germany), with a 1.7 mm triple tuned 1H-13C-15N NMR probe and a Carr-Purcell-Meiboom-Gill sequence (Bruker protocol cpmgpr1d, TOPSPIN 3.5, Bruker GmbH, Germany) with water suppression. Biochemical measurements comprise heat shock protein 70 abundance and catalase activity determined from whole-body tissue homogenates. The data were collected to characterize temperature-dependent physiological and behavioral responses of L. littorea across seasons and to identify thermal thresholds during acute warming exposure.

Harbour and grey seal counts in the Elbe Estuary, Germany, between Wedel and Scharhörn in 2023/2024

Aerial surveys were conducted in the Elbe Estuary, Germany, to count seals on their haul-out sites. Haul-out sites were located within the intertidal zone, usually close to the waterway or tidal creeks. The north-western border of the study area was located at the approximate river-km 753 (island of Scharhörn) and the south-eastern border was located at river-km 632 (Mühlenberger Loch). Flights were performed monthly from August 2023 until July 2024 (11 flights in total) at low tide. Within each month, a flight date in the middle of the month was chosen, depending on the tide and weather conditions. The flight scheduled for December 2023 had to be canceled due to persistently unfavorable weather conditions. Flights were performed with a twin-engined aircraft at a height of approximately 500 feet and at an average speed of 100 knots. The flight routes were tracked via GPS. Sighted seals were photographed on their haul-out sites and the corresponding geographic position was recorded. In the office, the photos were used to identify the species and age class, and count the animals.

Physiological measurements from controlled laboratory temperature experiments in non-native Vaucheria sp. turfs in the European Wadden Sea

This dataset describes the physiological temperature response of the intertidal macroalga Vaucheria sp. collected from the Wadden Sea near Sylt, Germany. The dataset provides insights into the thermal sensitivity of respiration and photosynthesis in Vaucheria sp. and can be used to assess physiological limits and potential responses of intertidal Vaucheria sp. to warming in temperate coastal ecosystems. Samples were collected in September 2024 from the lower intertidal zone and cultivated for three weeks under controlled laboratory conditions (15 °C, ~100 µmol photons m⁻² s⁻¹, 12:12 h light:dark cycle) before experimentation. The experiment was conducted in October 2024 in climate chambers at six temperature treatments (16, 20, 24, 28, 32, 36 °C). Physiological responses were assessed after 54 h of incubation. Each temperature treatment included four biological replicates. Respiration and net photosynthesis were quantified as oxygen consumption and production using fibre-optic optodes under four irradiance levels (0, 100, 500, 900 µmol photons m⁻² s⁻¹). Oxygen rates were normalised to algal wet weight. Photosynthetic performance was assessed using pulse-amplitude modulated (PAM) fluorometry, including measurements of maximum quantum yield of PSII (Fv/Fm), effective quantum yield (ΦPSII), non-photochemical quenching (NPQ) and rapid light curves.

High-resolution porewater salinity measurements across contrasting subterranean estuaries

This dataset provides high-resolution porewater salinity measurements used to investigate spatial variability within subterranean estuaries (STEs) across contrasting coastal settings. Field surveys were conducted at Marine Drive beach and Siali beach along the Odisha coast, India, and at Spiekeroog Beach, Germany. Sampling campaigns were performed during the post-monsoon season (October 2024) at Marine Drive and Siali beaches, during the pre-monsoon season (March 2026) at Marine Drive beach, and in June 2025 at Spiekeroog beach. Porewater was collected from the intertidal zone at 0.5 m sediment depth using a push-point sampler following meter-scale grid-based surveys to characterize lateral variations in fresh-saline mixing. Sampling locations were mapped using QField for QGIS connected via Bluetooth to a Trimble DA2 GNSS receiver with an active Catalyst subscription, enabling high-precision positioning and simultaneous recording of spatial coordinates with field measurements. Porewater salinity, electrical conductivity, and temperature were measured in situ using a WTW multiparameter probe (Xylem Analytics Germany). The measurements capture localized freshening zones and heterogeneous mixing patterns within STEs, highlighting the spatial complexity of fresh-saline mixing. This dataset supports the evaluation of lateral variability in SGD pathways and contributes to improved understanding of the spatial heterogeneity of STEs at the beach scale.
