Oxygen consumption rate, organic carbon and grain size data for intertidal sediments and oxygen concentration of pore waters data of Spiekeroog Island North Beach, May 2022 to April 2023

The permeable sandy sediments of beach aquifers receive a high input of electron acceptors, such as oxygen (O2), as well as fresh organic matter through seawater infiltration, driving the biogeochemical turnover in the subterranean estuary. Here, we experimentally determined seasonal sedimentary O2 consumption rates of intertidal sediments along a transect in the seawater infiltration zone at Spiekeroog Island North Beach, Germany, and present the data together with measurements of organic carbon and grain sizes, oxygen concentration of pore waters and beach topography. The samples were taken down to 1 m depth during two-monthly sampling campaigns from May 2022 to April 2023. Preliminary investigations of O2 consumption rates took place in in March, June and August 2017. Sediment and porewater sampling procedures were carried out as described by Massmann et al. (2023). O2 consumption rates were determined in slurry incubations of the retrieved sediments using gas tight vials (Labco Exetainer® 12 ml) equipped with O2 sensor spots (Pyroscience, OXSP5). Incubations were carried out in the dark at in situ temperatures, and vials were mounted on a rotating wheel to mimic porewater advection. The sediment's total organic carbon content was determined in a CS analyser (Eltra CS 800). Additionally, the fine fraction of the sediment was washed out and the organic carbon content of the fine sediments was measured in a CHNSO analyser (Hekatech Euro EA). The grain size distribution of the sediments was detemined using dynamic image analysis (Sympatec QICPIC). The O2 concentration in the pore water along the transect was measured immediately after the sample was taken using a flow-through oxygen optode (Pyroscience, OXFTC). The data was collected to investigate the impact of seasonal inputs and filtration efficiency on the O2 consumption during seawater infiltration into the permeable sands of beach aquifers.

Beach topography data of Spiekeroog Island North Beach, May 2022 to April 2023

Sandy beaches are highly dynamic land-ocean transition zones. For two-monthly sampling campaigns from May 2022 to April 2023, the beach topography along a sampling transect in the seawater infiltration zone at Spiekeroog Island North Beach, Germany, was obtained using Digital Elevation Models (DEMs) derived from aerial imagery during drone flights and manual Real-Time-Kinematic (RTK) differential GPS-surveys. In December 2022, the data was obtained using differential GPS measurements (Stonex S9 III Plus GNSS) because of unfavorable conditions for drone flights. These measurements were carried out in connection with sediment and pore water sampling along the transect during the campaigns. The data was collected to investigate the impact of morphodynamics on the O2 consumption during seawater infiltration into the permeable sands of beach aquifers.

Laser diffraction grain-size data of Late Glacial to present sediment cores from Schweriner See, NE Germany

This dataset contains laser diffraction grain-size distributions from five Late Glacial to present sediment cores recovered from the northern shore of Schweriner See (See = Lake, NE Germany). The cores (3.0–4.6 m long, 5 cm diameter) were collected using a percussion coring system from different geomorphological positions, including beach ridges, a lake terrace, and the base of a shore slope. One core (Döpe19/1) was obtained from the northeastern shore of Schweriner Außensee in the Döpe area, while four cores (HoVie05–HoVie08) were recovered from the Hohen Viecheln area in the north shore of Schweriner Außensee. Sediment cores were subsampled at 2 cm resolution, and grain-size measurements were performed using a Fritsch Laser Particle Sizer Analysette 22 MicroTec plus (0.08–2000 μm) following removal of organic matter and carbonates and ultrasonic dispersion.

Water content and loss-on-ignition data of Late Glacial to present sediment cores from Schweriner See, NE Germany

This dataset contains water content and loss-on-ignition data from five Late Glacial to present sediment cores recovered from the northern shore of Schweriner See (See = Lake, NE Germany). The cores (3.0–4.6 m long, 5 cm diameter) were collected using a percussion coring system from different geomorphological positions, including beach ridges, a lake terrace, and the base of a shore slope. One core (Döpe19/1) was obtained from the northeastern shore of Schweriner Außensee in the Döpe area, while four cores (HoVie05–HoVie08) were recovered from the Hohen Viecheln area in the north shore of Schweriner Außensee. The sediment cores were subsampled at 2 cm resolution. Water content and loss on ignition analyses were performed on 2–3 g of sediment placed in ceramic crucibles. Water content was determined after drying samples for 24 hours at 105 °C in a drying oven, while loss on ignition was calculated following combustion of organic matter for 4 hours at 550 °C in a muffle furnace.

Sources and Sinks of short-lived radium isotopes in the southern North Sea: Implications for the system functioning and budget estimates

Continued population growth increases the demand for space and resources, which in turn enhances anthropogenic pressure on coastal seas. Biotic and abiotic ecosystem understanding in a wider context is essential for effective management of stakeholder interests. This study is a synthesis of recent findings based on short-lived radium isotopes in the shelf ocean North Sea and uses the isotopes to quantify relevant sources and sinks in biogeochemical cycles in the coastal sea in order to enhance system understanding. We improve upon the previously designed box model for the southern North Sea by Burt et al. [2014], using a denser data coverage for nearshore areas. Specifically, the updated model considers decay-supported desorbable Ra from suspended particles and input from submarine groundwater discharge. The model quantified a total of five source terms for Ra: the Wadden Sea, rivers, desorption from suspended particles in the water column, submarine groundwater discharge from beach systems, and porewater exchange at North Sea bottom sediments; whereas considered losses are radioactive decay and mixing with the open North Sea. The mass balance reveals that porewater exchange, e.g., ripple flow, significantly dominates the total short-lived Ra isotope discharge to the southern North Sea. An eddy diffusion based Ra approach was not successful to quantify submarine groundwater discharge from beach systems, due to other major inputs of Ra isotopes from the adjacent Wadden Sea and river discharge, superimposing the minor submarine groundwater discharge from beaches.
