Research: From archive to wreck site

Interdisciplinary research

The North Sea Wrecks project features people with different expertise and from different countries working together to investigate military wrecks.

Research in archives

Trawling through documentation from the two world wars gives us initial clues as to the location of North Sea wrecks as well as information on their cargo.

Research cruises to the North Sea

The next step will be to plan cruises with research vessels to the North Sea to study the wreck and its immediate environment. By use of seismic and acoustic geophysical mapping of the seafloor, we are looking for a wreck site from which to take vital samples.

Scientific divers taking samples

Scientific divers and remoted controlled vehicles carry out investigations directly on the wrecks and collect water and sediment samples. Scratch samples from the wreck will provide information on how the fouling on the wreck is contaminated with pollutants.

Taking samples

While scientific divers collect samples underwater, the other researchers remain on board the ship, from where they will take water and sediment samples. They collect samples via oceanographic measuring instruments at different water depths.

Mussels are important for our research

Mussels play a special role in our research: divers place mussels near the wrecks and collect them again after a few weeks. Because mussels ingest their food through filtration, they can be analysed to determine the quality of the water.

We also catch fish

In addition, we use passive samplers for comparison samples, which filter the water in a similar way to the mussels. Furthermore, we also catch fish that can be analysed alongside the mussels and other samples back in the lab. The samples are prepared on board and stored temporarily before being taken to the lab for further examination on land.
