“…Other coastal bird species in NGOM that have been studied after the spill include northern gannet Morus bassanus (high oiling rate observed) (Montevecchi et al, 2012), North America loon Gavia immer (low but increased PAH concentrations in blood in 2012 indicate contaminated feed) (Paruk et al, 2014), dunlins Calidris alpina (100,000 individuals could have been affected by DWH oil, population also disturbed by beach clean-up) (Henkel et al, 2014). A study on the Canadian breeding population level of northern gannets, which partly over-winter in the northern Gulf area, found that their abundance and reproductive success had declined recently (Franci et al, 2014), but the study could not link this effect to the DWH oil spill or to differences in reproductive hormonal status in breeding birds returning from NGOM. It is difficult to interpret the significance of these observations without knowing the recovery rates of gannets after sublethal exposures to oil.…”

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.

“…Numerous ecological disasters have been caused by undesirable petroleum products spills, for example [2]: spill in Spain; 2010 -the BP Deepwater Horizon spill in the Gulf of Mexico, and regular petroleum leakages in the Niger Delta since 1958. Apart from financial losses, such incidents cause huge and sustained devastation in Earth's ecosystems and harm living organisms [3][4][5][6][7][8][9][10]. These environmental disasters together with some local scale incidents seriously endanger the environment.…”

“…These loggers also made it possible to track long-term migration to assess marine pollution impact (e.g. Deepwater Horizon oil spill in the Gulf of Mexico in April 2010 [62][63][64]). In North America, these studies confirmed knowledge from https://doi.org/10.1371/journal.pone.0230262.g005…”

Although there is a consensus about the evolutionary drivers of animal migration, considerable work is necessary to identify the mechanisms that underlie the great variety of strategies observed in nature. The study of differential migration offers unique opportunities to identify such mechanisms and allows comparisons of the costs and benefits of migration. The purpose of this study was to compare the characteristics of short and long-distance migrations, and fitness consequences, in a long-lived seabird species. We combined demographic monitoring (survival, phenology, hatching success) of 58 Northern Gannets (Morus bassanus) breeding on Bonaventure Island (Canada) and biologging technology (Global Location Sensor or GLS loggers) to estimate activity and energy budgets during the nonbreeding period for three different migration strategies: to the Gulf of Mexico (GM), southeast (SE) or northeast (NE) Atlantic coast of the U.S. Survival, timing of arrival at the colony and hatching success are similar for short (NE, SE) and long-distance (GM) migrants. Despite similar fitness consequences, we found, as expected, that the overall energetic cost of migration is higher for long-distance migrants, although the daily cost during migration was similar between strategies. In contrast, daily maintenance and thermoregulation costs were lower for GM migrants in winter, where sea-surface temperature of the GM is 4-7 o C warmer than SE and NE. In addition, GM migrants tend to fly 30 min less per day in their wintering area than other migrants. Considering lower foraging effort and lower thermoregulation costs during winter for long-distance migrants, this suggests that the energetic benefits during the winter of foraging in the GM outweigh any negative consequences of the longerdistance migration. These results support the notion that the costs and benefits of short and long-distance migration is broadly equal on an annual basis, i.e. there are no apparent carry-over effects in this long-lived bird species, probably because of the favourable conditions in the furthest wintering area.
