“…The major threats to the American horseshoe crab (i.e., those stressors that could impact population viability and lead to regional or species extinction) are commercial harvest for bait, production of a biomedical product, and marine life specimens for research, education, and aquaria Davis et al 2006;Brockmann et al 2015), spawning habitat loss (Botton et al 1994;Jackson and Nordstrom 2009), pollution (Venosa et al 1996;Strobel and Brenowitz 1981;Botton and Itow 2009), bycatch (Gerhart 2007), impingement by coastal infrastructure (including power plants) and climate change (Loveland and Botton 2015). Also, an emerging threat is the importation of Asian species for use as bait in the whelk and eel fisheries in the Mid-Atlantic region with the associated risk of introduction of pathogens, parasites, and non-native species .…”

Due to the toxicity of petroleum compounds, the increasing accidents of marine oil spills/leakages have had a significant impact on our environment. Recently, different remedial techniques for the treatment of marine petroleum pollution have been proposed, such as bioremediation, controlled burning, skimming, and solidifying. (Hedlund and Staley in Int J Syst Evol Microbiol 51: [61][62][63][64][65][66] 2001). This review introduces an important remedial method for marine oil pollution treatment-bioremediation technique-which is considered as a reliable, efficient, cost-effective, and eco-friendly method. First, the necessity of bioremediation for marine oil pollution was discussed. Second, this paper discussed the species of oil-degrading microorganisms, degradation pathways and mechanisms, the degradation rate and reaction model, and the factors affecting the degradation. Last, several suggestions for the further research in the field of marine oil spill bioremediation were proposed.

“…Although we have noted that successful bioremediation can be achieved if nutrients were applied in a trench landward of a fine-textured beach, these beaches are characterized by a low hydraulic conductivity, which implies that the nutrients might not reach the bioremediation zone before the high tide occurs. Therefore it appears that application of the nutrients onto the beach surface at low tide [Venosa et al, 1996] is the best application strategy. A refinement on the method used by Venosa et al [1996] for coarse beaches would be to apply the nutrient solution intermittently on the beach surface to provide sufficient moisture for microbial growth.…”

Abstract. Two laboratory experiments were conducted to investigate the effects of tides and buoyancy on beach hydraulics in the presence of a seaward groundwater flow due to an elevated "regional" water table. In the first experiment, case 1, the difference in concentration between the salt water at sea and the water of the regional aquifer was small, 2.4 g L -•, such that it did not engender density gradients; the salt acts as a tracer in this case. In the second experiment, case 2, the difference was --•32.0 g L -•, which creates a significant density gradient. This case corresponds to the presence of fresh groundwater in the subsurface of the coasts of the continental United States. The experiments were numerically simulated by the marine unsaturated (MARUN) model, a numerical model for density-and-viscosity-dependent flows in two-dimensional variably saturated media. The long-term experimental and numerical results showed that the seawater plume entered the beach from the sea and occupied most of the intertidal zone. The maximum depth of the seawater plume was near the midsection of the intertidal zone, and it decreased near the low and high tide lines. When viewed in the context of case 2, these results indicate an inverted salinity distribution in beaches subjected to tides with salt water from sea overtopping the freshwater lens. For both cases, water from the regional aquifer moved seaward beneath the seawater in the intertidal zone and pinched out near the low tide mark. We also noted that beach hydraulics are highly two dimensional with water entering the beach at a near-vertical angle and leaving it at a near-horizontal angle, which casts doubts on analyses of beach hydraulics based on the Dupuit assumption. Findings from this work have direct implications within the practice of bioremediation of oil spills on beaches. We found that applying dissolved nutrients on the beach surface at low tide is superior to applying them in a trench landward of the beach. This is because the residence time of the nutrient plume in the bioremediation zone of the beach in the prior situation is longer than that in the latter.

Bioremediation of an Experimental Oil Spill on the Shoreline of Delaware Bay

Abstract: Even though oil loss was enhanced by nutrient addition, active bioremediation in the form of exogenous nutrient addition might not be appropriate in cases where background nutrient levels are already sufficiently high to support high intrinsic rates of hydrocarbon biodegradation.
