IMO Guidelines for the Sampling and Identification of Oil Spills
This Section is intended to provide guidance to Governments, including those of developing countries, on the techniques, equipment and strategies for sampling oil to identify unknown sources of spilled oil. Although references are given for the laboratory methods required for analysis, the emphasis in this text is on the details of the field work required to collect the samples.
