As new and more intense forms of marine pollution threaten coastal ecosystems, economies, and communities, scientists from NOAA OR&R collaborate with leading experts on topics like marine debris, environmental economics, endangered species, environmental chemistry, and many other subjects that intersect with pollution science. This blog highlights some recently published scientific advances supporting pollution response and assessment.

Phillips Creek Marsh lies on the eastern seaside stretch of the Delmarva Peninsula in Virginia. The marsh is a swath of wetland grasses with patches of reeds and warped remnants of a boardwalk. Pines fringe the marsh, and a flock of seabirds socialize on a distant mudflat to the southeast.

The 2010 Deepwater Horizon oil spill resulted in significant environmental harm over a large area of the Gulf of Mexico and adjacent shorelines.

A special issue of Marine Ecology Progress Series published Aug. 3, 2017, features 9 scientific articles summarizing the impacts of the oil spill on northern Gulf of Mexico shorelines and nearshore areas.  The scientific studies, conducted by National Oceanic and Atmospheric Administration authors and partners, document four key findings based on five years of data collection and study.

There is no one-size-fits-all approach to environmental assessments for oil spills or hazardous waste events. We must therefore custom-tailor our technical approach for each pollution incident.

We first determine whether impacts to natural resources have occurred and whether it is appropriate to proceed with a Natural Resource Damage Assessment (NRDA). We collect time-sensitive data, evaluate available research and information about the type of injury, and determine what species and habitats are likely to have been affected. If we determine that habitats, wildlife or human uses have been harmed or could experience significant impacts, we often proceed with a full damage assessment.
