The Urban Waste Water Treatment Directive concerns the collection, treatment and discharge of urban waste water and the treatment and discharge of waste water from certain industrial sectors. The objective of the Directive is to protect the environment from the adverse effects of the above mentioned waste water discharges. This series contains time series of spatial and tabular data covering Agglomerations, Discharge Points, and Treatment Plants.

Wadden Sea carbon stock dynamics during thirty years of summer polder restoration

Salt marshes along the Wadden Sea coast are often shaped by anthropogenic alterations to their hydrology and sedimentation. To investigate the effects of hydrological restoration through summer dike openings on soil carbon storage capacities, soil samples were collected from four study sites along the Lower Saxony Wadden Sea coast, Germany. Each site featured restored areas, i.e., former summer polders reconnected to tidal exchange, and reference salt marshes adjacent to the polders. The polders varied in restoration age, i.e., 0 (control, not restored), 8, 14, and 28 years, forming a chronosequence for temporal analysis, while the reference salt marshes remained unchanged. Soil samples were taken along transects that represented different marsh zones, including pioneer, lower salt marsh, and upper salt marsh. The soil samples covered soil layers down to a depth of 100 cm and were collected in five sections of 20 cm using an Edelman corer. Total carbon, organic carbon, and inorganic carbon were analyzed using CN-elementary analysis and calcimeter methods. This dataset provides valuable insights into the potential of hydrological restoration measures to enhance soil carbon sequestration in salt marshes.

Analytical data from stepped thermal analysis of agricultural soils in Saxony

The continuous agricultural soil monitoring program (BDF) by the Saxon State Office for Environment, Agriculture, and Geology (LfULG) is operational since 1995, collecting and analysing samples periodically from 60 monitoring sites across Saxony, Germany. Stepped thermal analysis allows for the fast and cost-effective determination of different carbon fractions of ground soil samples. This dataset reports the analysis of 902 archive samples from the Soil Monitoring Program of the State Office for Environment, Agriculture, and Geology (LfULG) collected between 1995 and 2023, and 462 samples collected during a sampling campaign in September 2023. We report the thermal soil carbon fractions TOC400, ROC (ROC600), and TIC900 measured in air-dried and ground samples according to DIN19539 / DIN EN 17505 using an Elementar soliTOC cube. This dataset is part of a mid-infrared soil spectral library for agricultural soils in Saxony, Germany.

WISE WFD Reference Spatial Datasets reported under Water Framework Directive 2016 - INTERNAL VERSION - version 1.7, Jul. 2024

The dataset contains information on the European river basin districts, the river basin district sub-units, the surface water bodies and the groundwater bodies delineated for the 2nd River Basin Management Plans (RBMP) under the Water Framework Directive (WFD) as well as the European monitoring sites used for the assessment of the status of the above mentioned surface water bodies and groundwater bodies. This data set is available only for internal use of the European Commission and the European Environment Agency. Please use the "PUBLIC VERSION": https://sdi.eea.europa.eu/catalogue/srv/eng/catalog.search#/metadata/a0731ebf-6bcc-4afe-bab0-39e7aa88eaba for external use. The information was reported to the European Commission under the Water Framework Directive (WFD) reporting obligations. The dataset compiles the available spatial data related to the 2nd RBMPs due in 2016 (hereafter WFD2016). See http://rod.eionet.europa.eu/obligations/715 for further information on the WFD2016 reporting. See also https://rod.eionet.europa.eu/obligations/766 for information on the Environmental Quality Standards Directive - Preliminary programmes of measures and supplementary monitoring. Where available, spatial data related to the 3rd RBMPs due in 2022 (hereafter WFD2022) was used to update the WFD2016 data.

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.

Carbonate chemistry speciation of the 2023 KOSMOS Helgoland experiment on the effects of ocean alkalinity enhancement on pelagic foodwebs

This dataset contains carbonate chemistry speciation data of the 2023 KOSMOS mesocosm study on Helgoland, Germany. This study tested the effects of ocean alkalinity enhancement simulating lime additions on pelagic ecosystem functioning during a spring bloom. Carbonate chemistry speciation (fCO2, pHT, calcium carbonate saturation state) was generally calculated from measurements of total alkalinity (TA) and dissolved inorganic carbon (DIC) in depth-integrated water samples. There were 12 mesocosms in total and in 6 of them an alkalinity gradient of up to +1250 umol/kg was established in steps of 250 umol/kg. In the remaining 6 the same amount of alkalinity was added only to the upper portion of the mesocosms, resulting in twice the alkalinity increase there, before being mixed in after 48 hours. The two treatments simulated the immediate dilution of TA after ship deployment as well as a delayed one from a point source.
