CHEMSEA is an applied-research project aimed at linking science with administration and policy. This is reflected by the partnership composition: on one hand the team includes civilian, military and oceanographic research institutes whose expertise is hazardous substances, such as chemical warfare agents dumped in the Baltic Sea. On the other hand, CHEMSEA also brings in maritime, military, environmental and other authorities in charge of taking decisions related handling of these chemical warfare agents.
Keeping in mind the challenges that exist in the transfer of knowledge between the research community and the different administrations, the CHEMSEA partnership was designed as a cooperation between at least one research institute and one relevant administration in each of the participating countries. In addition to the partners, several associated organisations have declared their commitment and willingness to take an active role in the project.
