“…Corroborating observations of oysters displaying no significant oil carbon uptake in oil affected coastal areas were reported by several other field studies, e.g., Soniat et al (2011), Carmichael et al (2012b), Xia et al (2012). Snyder et al (2014a; measured oil spill related PAHs in samples of sand and coquina clams from oiled FL Panhandle beaches. They found that both types of samples displayed decreasing concentrations post spill, reaching undetectable levels within one and two years after oiling, respectively.…”

The Deepwater Horizon oil spill constituted an ecosystem-level injury in the northern Gulf of Mexico. Much oil spread at 1100-1300m depth, contaminating and affecting deepwater habitats. Factors such as oil-biodegradation, ocean currents and response measures (dispersants, burning) reduced coastal oiling. Still, >2100km of shoreline and many coastal habitats were affected. Research demonstrates that oiling caused a wide range of biological effects, although worst-case impact scenarios did not materialize. Biomarkers in individual organisms were more informative about oiling stress than population and community indices. Salt marshes and seabird populations were hard hit, but were also quite resilient to oiling effects. Monitoring demonstrated little contamination of seafood. Certain impacts are still understudied, such as effects on seagrass communities. Concerns of long-term impacts remain for large fish species, deep-sea corals, sea turtles and cetaceans. These species and their habitats should continue to receive attention (monitoring and research) for years to come.

“…Previous work found that sediment samples in this region of the Gulf of Mexico tend to show large differences in PAH concentrations due to their proximity to the mouth of the Mississippi River, where a variety of newly deposited sediment types are within close proximity of each other . The high variation in tPAH concentrations may also result from the uneven distribution of sedimented organic detritus in the sampling area . Moreover, beach raking activities, which can expose subsurface sediments and accelerate photooxidation, and beach nourishment activities, which dredge material from offshore sites and deposit it in intertidal and dune zones, , are common practices at many Gulf sites, including Grand Isle .…”

Shorebirds depend on staging sites in the Gulf of Mexico that are frequently subject to pollution by oil and its toxic constituents, polycyclic aromatic hydrocarbons (PAHs). It was hypothesized that PAH contamination lowers staging site quality for migratory shorebirds, with consequences for fueling and departure timing. Sediment total PAH concentrations were measured at six staging sites along the Texas and Louisiana Gulf Coast. Sites in Louisiana were expected to have higher total PAH concentrations as they were more heavily impacted by the Deepwater Horizon oil spill. From 2015 to 2017, 165 Sanderling (Calidris alba) and 55 Red knots (C. canutus) were captured at these same sites during their northward migration (late April to mid May). Mass, body morphometrics, and plasma metabolite measurements were taken to determine fuel loads and fueling rates, and a subset of birds (120 Sanderling and 39 Red knots) received a coded radio tag to determine departure dates using the Motus telemetry array. Compared to Texas sites, sediment in Louisiana had higher total PAH concentrations, dominated by heavier 6 ring indeno[1,2,3-cd]pyrene (48%). Plasma metabolite profiles suggested that fueling rates for Sanderling, but not Red knots, tended to be lower in Louisiana, and both species departed later than the study average from Louisiana. However, multiple factors, including migration patterns, food supply, and other contaminants, also likely influenced fueling and departures. PAH contamination in the Gulf of Mexico remains an ongoing issue that may be impacting the staging site quality and migration timing of long-distance migratory birds.

“…Low levels of PAHs derived from the DWH spill have also been detected in coastal sediments (Snyder and et al, 2014a) and shellfish (coquinas, Donax spp.) along the sandy beaches of the Florida Panhandle (Snyder and et al, 2014b).…”
