−Deployment of “snare sentinels” at selected locations . Snare sentinels consist of anchors attached to a rope with snare (white pom poms) attached to it from the seafloor to the surface
−After 24 hours, the snare sentinels will be pulled up and inspected visually for any oil. Use our standard descriptors to estimate the % oil cover, particle size, color, etc.
−If not oiled, they will be replaced for another 24 hour period.
−If oiled, the snare will need to be photographed, removed, bagged for disposal, and replaced with clean snare. Representative samples will be collected from oiled snare.
−File a report describing the methods and results with a map showing the locations and oiling summary, photographs, and recommendations for any additional assessments.
