It is important that we collect samples consistently and properly to assure the quality of the information needed by decision makers. This report explains the procedures for sampling water, sediment, benthic invertebrates, and microorganisms.
Locations of survey points, a photographic record of each site, field observations of vegetation cover and descriptions of oil coverage in the water and on plants, including measurements of the distance of oil penetration from the shoreline.
