Waterbase - Biology, 2024

Waterbase serves as the EEA’s central database for managing and disseminating data regarding the status and quality of Europe's rivers, lakes, groundwater bodies, transitional, coastal, and marine waters. It also includes information on the quantity of Europe’s water resources and the emissions from point and diffuse sources of pollution into surface waters. Specifically, Waterbase - Biology focuses on biology data from rivers, lakes, transitional and coastal waters collected annually through the Water Information System for Europe (WISE) – State of Environment (SoE) reporting framework. The data are expected to be collected within monitoring programs defined under the Water Framework Directive (WFD) and used in the classification of the ecological status or potential of rivers, lakes, transitional and coastal water bodies. These datasets provide harmonised, quality-assured biological monitoring data reported by EEA member and cooperating countries, as Ecological Quality Ratios (EQRs) from all surface water categories (rivers, lakes, transitional and coastal waters).

Master tracks in different resolutions of ALKOR cruise AL644, Kiel - Kiel, 2025-11-17 - 2025-11-28

Raw data acquired by position sensors on board RV Alkor during expedition AL644 were processed to receive a validated master track which can be used as reference of further expedition data. During AL644 data from the Seapath 330 system, the Furuno GP-170 and the Furuno GP-150 GPS receivers were used to calculate the mastertrack. Data were downloaded from DAVIS SHIP data base (https://dship.bsh.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.

Water column, solid phase and porewater data in the Kiel Bight, SW Baltic Sea from 2016 to 2025

During the research cruises BE03/2016 (08.03.2016), BE10/2016 (19.10.2016), BE10/2018 (23.10.2018), BE03/2019 (15.03.2019), L23-13 (13.09.2023 - 15.09.2023), Sagitta24-1 (16.09.2024), Sagitta24-2 (23.09.2024), Hai24VE2 (24.09.2024), L25-2b (09.02.2025 - 17.02.2025) and EMB374 (04.09.2025 - 13.09.2025), CTDs were deployed and sediment corers were retrieved at 99 stations in Kiel Bight in the southwestern Baltic Sea. Water column oxygen concentrations were determined using oxygen sensors attached to the CTD framework. At selected water depths, water samples were collected with Niskin bottles for the analysis of nitrate concentrations using an autoanalyzer. Short sediment cores (<50cm) were recovered using a Multicorer (MUC), Minicorer (MIC) or Rumohrlot (RL). Bottom waters were sampled from the supernatant water in the sediment cores. Solid phase sediment samples were analyzed for total organic carbon using an element analyzer. Porewater was extracted from the sediment cores using rhizones and analyzed for total alkalinity (titration), ammonium (photometer), sulfate (ion chromatography), hydrogen sulfide (photometer), dissolved iron (ICP-OES) and dissolved manganese (ICP-OES). The collected data will be used to (i) determine the spatial and temporal variability of hydrogen sulfide in bottom waters of the Kiel Bight, (ii) identify the controlling factors governing the accumulation of hydrogen sulfide at the seafloor, and (iii) establish an early warning system of sulfidic seafloor conditions for regional stakeholders in the Baltic Sea.

ADCP current measurements (600 kHz) on RV HEINCKE during RV HEINCKE cruise HE667

Ocean velocities were collected by a Teledyne RDI 600 kHz Workhorse Mariner ADCP that was mounted on RV HEINCKE during RV HEINCKE cruise HE667. The transducer was located at 4 m below the water line. The instrument was operated in single-ping, broadband mode with bin size of 1 m and a blanking distance of 1 m. The velocity of the ship was calculated from position fixes obtained by the Global Positioning System (GPS) received directly from RV HEINCKE. Heading, Pitch and Roll were obtained both from the MRU of RV HEINCKE and the internal ADCP gyro. Heading as well as pitch and roll data from ADCP's internal gyrocompass and the navigation and motion data were used by the data acquisition software ViSea DAS (AquaVision®) internally to convert ADCP velocities into earth coordinates. Accuracy of the ADCP velocities mainly depends on the quality of the position fixes and internal ADCP heading data. Further errors stem from a misalignment of the transducer with RV HEINCKE's centerline. ADCP data is provided at minutely sample rate. Raw data or secondly binned data are available on request.

Stable isotope analysis of the common periwinkle Littorina littorea depending on infection status and seasonality

Littorina littorea was collected at the study site. The foot of Littorina littorea was used for stable isotope analysis (δ15N and δ13C). The stable isotope composition of possible food sources was also determined. Samples were taken in spring, summer and autumn. For the analysis a diet tissue discrimination factor (DTDF) of 2.4 for δ15N and 1.0 for δ13C was subtracted, respectively. The data in the sheet are the raw data without the DTDF.

Phylogeny of bothropoid pitvipers (genera Bothrops, Bothrocophias)

Together with several colleagues from Argentina and Peru (main investigator is Paola Carrasco (Universidad Nacional de Cordoba), but also Gustavo Scrocchi (CONICET and Instituto de Herpetologia, San Miguel de Tucuman), Pablo Venegas (Centro de Ornitologia y Biodiversidad (CORBIDI), Lima), Juan Chaparro (Universidad Nacional de San Antonio Abad del Cusco, Cusco)), we started a collaboration on the phylogeny of bothropoid pitvipers (Bothrops, Bothrocophias), with the aim to solve systematic conflicts within the Bothrops-complex (to agree 50 species) using a phylogenetic analysis combining a large number of morphological and molecular data. Until recently, most phylogenetic analyses of the South American pitviper genus Bothrops used exclusively mitochondrial DNA sequences, whereas few of them have included morphological traits. Moreover, the systematic affinities of some species remain unclear. As part of this project we are currently working on a systematic revision of the Bothrops-complex in Peru (11 + 2 new species). We recently published the first data including the description of a new species (Carrasco et al. 2019) and a manuscript with the description of a second new species is in preparation. Additionally, the morphological variability in the Bothrops neuwiedii species group will be examined, with special respect to the widely distributed B. diporus. Bothrops diporus shall serve as a model species for studying possible influences of environmental factors on the phenotypical diversity of species in the genus Bothrops. The collaborative work started mid of 2015. First results of the collaborative project were presented at the XVI Congreso Argentino de Herpetología in San Miguel de Tucumán (September 2015), the I Congreso Argentino-Paraguayo de Herpetologia in Posadas, Argentina and Encarnación, Paraguay (September 2016), the XVIII Congreso Argentino de Herpetologia in Salta, Argentina (October 2017), the Latinamerican Congress of Herpetology in Quito, Ecuador (July 2017), and will be presented at the 3rd Biology of Pitvipers Symposium in Rodeo, USA (July 2019). Paola Carrasco just submitted a proposal to SYNTHESYS+ to visit the ZFMK in early 2020, in which I will serve as her host. In this visit, besides intensifying our collaboration, Paola wants to study different genera of Viperidae from our collection in the framework of our collaborative project.

Historical mapping of canals and ditches and the Danube surface water area in the Greater Donaumoos Region over the last 235 years

This dataset focuses on the historical mapping of the Greater Donaumoos fen region using old maps spanning the last 235 years. The main observations include the georeferencing of these historical maps and the subsequent vectorisation of the anthropogenic ditches and the Danube's surface area. The data collection encompasses maps spanning multiple centuries, providing temporal coverage that highlights landscape changes over significant historical periods. The data was collected to enhance archaeological, historical, and ecological research, offering insights into past landscapes and their transformations over time. The method involved digitising old maps and applying geospatial techniques to align them accurately with current geographical coordinates (Schmidt et al., 2024). This process was essential to create vector data representing the historical state of the ditches and the Danube river in this region. The purpose of this data collection is to provide a valuable resource for researchers studying historical land use, environmental changes, and regional development. The georeferencing and vectorisation processes were conducted using QGIS, ensuring precise alignment and accurate representation of historical features. The data generated from this project is crucial for understanding how the Greater Donaumoos fen region has evolved, offering a foundational dataset for further interdisciplinary studies.

Monitoring of CO2 emissions from passenger cars Regulation (EU) 2019/631

The Regulation (EU) No 2019/631 requires Countries to record information for each new passenger car registered in its territory. Every year, each Member State shall submit to the Commission all the information related to their new registrations. In particular, the following details are required for each new passenger car registered: manufacturer name, type approval number, type, variant, version, make and commercial name, specific emissions of CO2 (NEDC and WLTP protocols), masses of the vehicle, wheel base, track width, engine capacity and power, fuel type and mode, eco-innovations and electricity consumption. Data for EU-27 and UK are reported in the main database.

National systems for policies and measures and greenhouse gas projections, 2025

National systems include all relevant institutional, legal and procedural arrangements established within a country for reporting on greenhouse gas emissions policies and measures, for evaluating policy, and for making projections of anthropogenic greenhouse gas (GHG) emissions by sources and removals by sinks. Countries have to operate a national system, while also seeking to continuously improve it. Within the EU climate governance framework, national systems serve as the backbone for planning, monitoring, and reporting processes. A complete and transparent national system is essential to deliver good-quality information on GHG projections to integrate policy effects and understand GHG emission trends. It seeks to ensure the timeliness, transparency, accuracy, consistency, comparability and completeness of the information on policies and measures and GHG projections. The dataset covers all EU Member States, as well as Iceland, Switzerland and Norway. The data had to be reported in 2021, in line with Article 39 of the Governance of the Energy Union and Climate Action Regulation (EU) 2018/1999; however, each year a country can update data related to national systems, if modifications to the information exist. Therefore, some countries update data annually. Data is officially reported by national administrations and it is collected via the European Environmental Agency’s survey tool Reportnet 3.
