“…NRDA results are generally consistent with those found in other studies after the spill, where concentrations of oil components were elevated in wetland soil (Keevan 2012, Lin & Mendelssohn 2012, Turner et al 2014, Atlas et al 2015, submerged sediment (Floyd et al 2012, Sammarco et al 2013, nearshore surface water (Allan et al 2012, Sammarco et al 2013, and biological tissues (Xia et al 2012, Sammarco et al 2013.

The interconnected nearshore habitats of the northern Gulf of Mexico provide refuge and feeding opportunities for fish and wildlife, including open water, shoreline, and terrestrial species. The Deepwater Horizon oil spill natural resource damage assessment documented injury as a result of the oiling of over 2113 km (1300 miles) of shoreline over an 87 d release from the wellhead. Field and laboratory studies indicate that oil degraded the health of coastal marsh vegetation and associated fauna, resulted in the loss of nearshore oyster cover, and increased erosion of oiled marsh edge habitat over approximately 174 km (108 miles) of shoreline. Sand beach habitat, submersed aquatic vegetation, and subtidal oysters were injured by a combination of oiling and response actions. The loss of billions of oysters resulted in failed recruitment over several years in the most severely affected areas (Barataria Bay, Black Bay/Breton Sound, and Mississippi Sound). Affected ecosystem services include supporting services (e.g. primary production) and provisioning services (e.g. fish and invertebrate abundance). Loss of vegetation and nearshore oysters and increased shoreline erosion may have disrupted regulating services associated with stable marsh (e.g. coastal storm and flood protection). The loss of marsh vegetation and oysters likely reduced nutrient cycling and water filtration services. Recovery of natural resources may take more than 20 yr in some areas. To prepare for future spills, we recommend that natural resource trustees develop generic conceptual models and prepare integrated injury assessment approaches for nearshore habitats to facilitate future injury quantification. Additional exploration of the trade-offs between response options could minimize or shift natural resource injury for future spills.

“…In seabird colonies, successful annual reproduction was still 70% lower than historical rates, 5 yr after the Prestige oil spill (Barros et al 2014). Reproductive and early developmental effects have also been documented in fish species exposed to oil from the Exxon Valdez, Prestige, and Deep water Horizon spills (Hawkes & Stehr 1982, Kocan et al 1996, Bilbao et al 2010, de Soysa et al 2012, Kawa guchi et al 2012, Whitehead et al 2012, Turner et al 2014.…”

Following the Deepwater Horizon (DWH) oil spill, reproductive success rates in 2 northern Gulf of Mexico (GoM) bottlenose dolphin stocks exposed to oil were evaluated for 4 yr during and after the spill (2010 to 2015) in efforts to assess population-level reproductive health. Pregnancy was determined from either (1) ultrasound examinations of the reproductive tract during capture-release health assessments, or (2) endocrine evaluations of blubber tissue collected from dart biopsies of free-ranging dolphins. Follow-up photo-identification was then used to track the status of pregnant females and any associated neonatal calves for a minimum of 1 yr after the initial pregnancy detection (IPD). For all pregnant females observed following IPD, individuals seen with a calf (reproductive success) and without one (reproductive failure) were recorded. The resulting estimated reproductive success rates for both GoM stocks (19.4%; 7/36) were less than a third of those previously reported in other areas not impacted by the spill (i.e. Sarasota Bay, FL; Indian River Lagoon, FL; and Charleston Harbor, SC) using similar techniques (64.7%; 22/34). We also evaluated the relationships between reproductive success and 13 potential covariates, including stock, ordinal date, progesterone, cortisol, thyroid hormone concentrations, leukocyte count, lung health score, and total body length. Among these, the results only provide strong evidence (Bayes factor > 20) of a relationship between reproductive failure and the total leukocyte count covariate. The high reproductive failure rates measured in both GoM stocks following the DWH oil spill are consistent with mammalian literature that shows a link between petroleum exposure and reproductive abnormalities and failures.

“…Venosa et al (1996) studied the estimated decay-rate of a sandy beach with aerated soils for the control plots, and reported decay-rates of À2.6% and À2.1% day À1 for total alkanes and total aromatics, respectively. A similar work showed a lower decay-rate for coastal marshes, with a rate of À0.39% day À1 observed for the total alkane pool (Turner et al, 2014). For the works mentioned, the decay-rate constants in the artificial weathering simulation experiments were lower than what has been observed in the natural environment.…”

a b s t r a c tIn order to compare the effects of weathering on two types of mixed oil, simulated weathering experiments were performed. The first sample was a mixture of two fresh oils and the second sample was a mixture of one fresh oil and another oil sample that had undergone a serious weathering process. Comparative studies evaluated decay rates and changes in diagnostic ratios of some fingerprinting biomarkers. Results showed that the mixing process affected the weathering rate of some compounds in the oils and also that certain diagnostic ratios are more suitable for estimating mixing proportions. A Pr/n-C 17 versus Ph/n-C 18 plot can be used to identify the end-numbers of mixed oils and the (C 13 + C 14 )/(C 25 + C 26 ) ratio is a useful diagnostic ratio to detect the degree of weathering. Finally, hopane, sterane, and alkylated PAH fingerprints were found to give useful insights about the sources of the mixed oils.
