Comparative investigations of oiled seabirds and beaches in the Netherlands, Denmark, and the Federal Republic of Germany

The Oiled Seabirds project (January 3, 1990, to March 31, 1993) consisted of two parts: regular surveillance of the beaches in the Netherlands, Denmark, and the Federal Republic of Germany, and sampling and analysis. The aims of the project were: To identify and compare the main sources of oil pollution in the countries involved; To trace definite sources (i.e., particular ships), in more severe cases, to promote prosecution of the offenders; and To gauge the efficiency of countermeasures, e.g., the joint material surveillance in the countries involved. Although the term open-quotes oiledclose quotes was used in the project title, the investigations were not restricted to petroleum. An attempt was made to identify all the products that could have caused the deaths of seabirds. The major sources of oil pollution in the Netherlands and Germany appear to be from normal shipping operations, e.g. engine room residues, while in Denmark the major component of chronic oil pollution is crude oil from tank washings of tanker ships
