CONMAR 2:
DAM Schutz und Nutzen-2: CONcepts for conventional MArine munition Remediation in the German North Sea and Baltic Sea; project: Modelling the drift of explosive-type compounds (STV) in coastal oceans and investigating clearance strategies

Coastal waters worldwide are contaminated with munitions remnants from the World Wars; specifically, in
the German parts of the North and Baltic Seas, there are about 1.6 million tons of munitions. The precise
distribution and condition of this munition in German waters are largely unknown. This munition not only
poses a risk of explosion and safety concerns but also contains cytotoxic, genotoxic, and carcinogenic
chemicals that are associated with conventional explosives, chemical warfare agents, and other munition
components.
The goal of the CONMAR-Cmod project is to integrate existing and new datasets on historical marine
munitions into an oceanographic modeling system. This is intended to enhance our scientific understanding
of the role, fate, and environmental impacts of marine munitions. Additionally, the project aims to develop
political solutions for monitoring and remediation of the affected areas in cooperation with stakeholders.
The modeling system allows for the simulation and optimization of monitoring and remediation measures to
create socially acceptable and cost-effective solutions.
