These data represent marine waters where ocean dumping occurs, which includes the deliberate legal dumping of dredged spoils and other materials into ocean waters. Excludes sewage discharge, mining and mineral extraction.
Ocean dumping that occurs in the study area is mainly associated with dredge spoils near ports, harbors and river mouths. It can also include the dumping of fish waste and ballast water throughout the study area. More questionable is the illegal dumping of plastics and nuclear waste. The majority of the use occurs as dredge spoils in the EPA Region 10 ocean dumping sites. Tribal uses of the ocean were not mapped explicitly, though tribal chairs and/or their designated representatives were formally invited by BOEM to participate in the mapping workshops. The sharing of tribal use information was dependent upon each tribe’s determination of whether the mapping workshops were an appropriate forum for sharing such information. Any tribal use information shared during the workshops was incorporated into the defined use categories. Thus, the atlas data and map products do not explicitly depict tribal use. |
