Health status of dab (Limanda limanda) exposed to dumped munition in German coastal waters

Conventional munition dumped into the North Sea and the Baltic Sea close to the German coastline is corroding. A major concern is that biota, including fish, are negatively affected by toxic explosives leaking into marine environments. With the present study, we investigated fish living in close proximity to munition dumping sites for contamination and for signs of health impairments. The flat fish species common dab (Limanda limanda) was used as a model, since it lives in the vicinity of dumping sites and exhibits minor migratory activity. Various health indicators (body condition factors, externally visible fish diseases, parasites or liver anomalies) were investigated.

Chemical analysis of explosive chemicals in water, sediments, and mussels (Mytilus spp.) from three shipwrecks from World War I and II in the North Sea

This dataset contains the results of chemical analyses of water, sediment, and marine bivalves (Mytilus spp.) for residues of submerged munitions, which were taken during various field excursions to three wrecks from the First and Second World Wars in the North Sea: KW58 (Belgium), SMS Mainz (Germany), and UC30. Water and sediments were collected using CTD rosette water samplers and Van Veen sediment grabs (SMS Mainz), or by divers (KW58 and UC30). The mussels for mussel monitoring were collected near the island of Sylt (Germany) and exposed in cages on the wrecks for several weeks. Samples were frozen immediately on board and transferred to the lab for examination. All samples were analyzed for the explosive 2,4,6-trinitrotoluene (TNT) and its two primary metabolites, 4-amino-2,6-dinitrotoluene and 2-amino-4,6-dinitrotoluene, using gas chromatography tandem quadrupole mass spectrometry (GC-MS/MS).

Mercury and explosive compound 4-aminodinitrotoluene (4-ADNT) in dab (Limanda limanda) caught at munition dumping site Kolberger Heide in the Kiel Bight, Baltic Sea

Dumped munitions contain various harmful substances which can affect marine biota like fish. One of them is mercury (Hg), included in the common explosive primer. Another is 4-aminodinitrotoluene (4-ADNT), an explosive-metabolite. 251 individual dab (Limanda limanda L.) caught at the dump site Kolberger Heide a and nearby reference sites in 2017 and 2018 were analysed. The table contain individual data on Hg, 4-aminodinitrotoluene, age, length, weight, sex and condition factor.

Contamination of dab (Limanda limanda) with explosive chemicals leaking from marine dumped munition

Conventional munition dumped into the North Sea and the Baltic Sea close to the German coastline is corroding. A major concern is that biota, including fish, take up toxic explosives leaking into marine environments. With the present study, we investigated bile fluids of fish living in close proximity to munition dumping sites for the explosives 2,4,6-trinitrotoluene (TNT), its metabolites 2-amino-4,6-dinitrolouene and 4-amino-2,6-dinitrolouene as well as octahydro-1,3,5,7-tetranitro-1,3,5,7-tetrazocine (HMX) using HPLC-MS/MS (high performance liquid chromatography with mass selective detection) as device. The flat fish species common dab (Limanda limanda) was used as a model, since it lives in the vicinity of dumping sites and exhibits minor migratory activity.

Munition pile inventory in the German Baltic Sea, 2017 to 2024

The dataset is a spreadsheet of munition piles, their properties (e.g., number of objects, variability, burial state), and the parameters characterizing their environmental (e.g., munition compound concentrations and current velocity) and maritime (e.g., distance to various maritime uses and traffic density) surroundings in the German Baltic Sea. Data were collected over numerous cruises from 2017 to 2024. All munition piles in the dataset are located at Kolberger Heide (close to Kiel Fjord) or in the Lübeck Bay. The purpose of data acquisition was to understand the distribution and properties of dumped munitions in German waters as well as the hazards and risks they pose to maritime uses. Munition piles were annotated in multibeam echosounder data, assessed in detail in photomosaics, and analyzed using an array of geospatial analysis methods.

A multi-biomarker approach using caged blue mussel, Mytilus edulis, on three World War shipwrecks in the North Sea

This dataset contains results from a field-based exposure study assessing the biological effects of submerged munitions on the marine bivalve Mytilus spp.. Mussels were collected from Sylt Island (North Sea) and exposed at three historic munition wrecks: SMS Mainz (Germany), KW58 Hendericus (Belgium), and UC30 (Denmark). At each site, mussel cages were deployed directly on or near the wreck structures for several weeks. After recovery, mussels were assessed for mortality and dissected for histochemical and biochemical analyses. Tissues (gills, mantle, and digestive gland) were examined for histological biomarkers including lipofuscin, glycogen, neutral lipids, as well as sex and gonadal maturity. Enzymatic activities of catalase (CAT) and glutathione S-transferase (GST) were measured spectrophotometrically and normalized to protein content.

Chemical analysis for explosive compounds in water, sediment, and flatfish Limanda limanda (dab) collected from shipwrecks in the North Sea to assess the biological effects of old World War munitions

This dataset documents field investigations on release of legacy World War I munition explosive compounds into the surrounding marine environment, with a focus on shipwreck sites in the North Sea. Three historically well-documented wrecks were selected: the light cruisers SMS Mainz and SMS Ariadne, and the minelayer submarine UC30. These wrecks were chosen based on detailed archival information regarding their sinking circumstances and cargo, their unambiguous identification, and their accessibility for scientific diving operations. As a munition-free control, a reference area outside known wreck fields was sampled (Naturschutzgebiet Borkum Riffgrund). The flatfish Limanda limanda (dab) was selected as a sentinel species. Sampling was conducted during several cruises with the research vessel Heincke (HE 573, April 2021 – SMS Mainz; HE 596, April 2022 – UC30 and SMS Ariadne; HE 607, September 2022 – UC30; HE 613, February 2023 – SMS Ariadne) and with the Uthörn (May 2022 – reference site). Water was sampled with a CTD rosette water sampler at different depths and processed on board by solid phase extraction at 4 °C. Sediment was sampled with a Van Veen grab sampler and frozen at -20 °C. Fish were caught using bottom trawls deployed as close as possible to the wreck structures. Captured fish were transferred to seawater tanks prior to dissection. Each specimen was measured, weighed, and assessed biometrically to calculate condition factors as indicators of general health. Tissue samples were immediately frozen in liquid nitrogen and stored at -20 °C. Samples were processed in the lab according to established protocols. All samples were analyzed by gas chromatography triple quadrupole mass spectrometry (GC-MS/MS) for the explosive TNT and its metabolites 2- and 4-ADNT.

Munition pile inventory in the German Baltic Sea, 2017 et seq

The publication series contains spreadsheets of munitions, their properties (e.g., number of objects, variability, burial state), and the parameters characterising their environmental (e.g., munition compound concentrations and current velocity) and maritime (e.g., distance to various maritime uses and traffic density) surroundings in the German Baltic Sea. Data are collected over numerous cruises starting in 2017. The purpose of data acquisition is to understand the distribution and properties of munitions in German waters as well as the hazards and risks they pose to maritime uses. Munitions are annotated in larger area datasets (usually multibeam echosounder or sidescan sonar data), assessed in detail (usually visually in photomosaics or videos), and analysed using an array of geospatial analysis methods.
