    Description: In recent years, there have been significant advances in fluid dynamics/physical oceanography, microbiology, weathering, remote sensing, and analytical chemistry as they pertain to the fate and effects of oil spills. Effects of the Deepwater Horizon oil spill on water column organisms and ecosystems have been difficult to ascertain. Laboratory experiments have expanded understanding of oil effects on phytoplankton and zooplankton. “Marine oil snow” has been identified as a significant factor in the fate of oil chemicals and their deposition with sediments. Oil chemicals and their effects on 24 km2 of mud-benthic communities surrounding the well site, and in a few other areas, have lasted several years. Some deep-sea corals have also been affected for several years, and oil chemicals and their effects in heavily oiled marsh areas are projected to last a decade or longer. Lightly oiled marsh areas have recovered or are recovering. Research about use of dispersants highlights the need to update the 2005 National Research Council study of dispersant use on oil spills. Ongoing research should provide some closure for the issues of long-term effects on fisheries and marine mammals, and impacts on human health. Practical uses of this new knowledge are discussed briefly.

    Description: The studies described in this thesis were designed to answer several problems relating to the recovery of a salt marsh heavily polluted by an accidental spill of Number 2 fuel oil. Field and laboratory studies were conducted for 5 years comparing the oiled Wild Harbor Marsh with the unoiled Sippewissett Marsh, both on Buzzards Bay in Massachusetts. The data contributes information 1) on the incorporation of oil into the sediments and organisms at the oiled marsh, 2) on the residence times of certain components of the oil in the marsh ecosystem, 3) on changes in chemical composition of the oil with time due to physical and chemical weathering processes and biochemical degradation of hydrocarbons, 4) on the effects of oiled sediments on the population distribution, behavior, and survival of the intertidal fiddler crab, Uca pugnax, 5) on the relatively small ability of Uca to metabolize hydrocarbons, 6) on the presence of an inducible in vitro microsomal mixed function oxidase (MFO) enzyme system in the marsh minnow, Fundulus heteroclitus, 7) on the presence of high MFO rates in field populations of Fundulus exosed to hydrocarbon pollution, and 8) for the synthesis into a discussion of some of the physiological reasons for the relative sensitivity of marsh animals to oil pollution and their relative ability to adapt to an oil polluted environment.

    Description: The oil barge "Florida" ran aground just off Little Island, West Falmouth, Massachusetts on September 16, 1969. About 175,000 gallons of Number Two fuel oil leaked into Buzzards Bay and the adjacent Wild Harbor Marsh. This report presents the results of analyses done on marsh muds and organisms collected nearly a year after the spill. We studied the incorporation of polluting hydrocarbons into, and their movement through the marsh ecosystem. Analyses of surface muds agreed well with observations on plant growth. The dead areas were the most heavily polluted. A deep mud core in the dead area showed oil has penetrated to at least 70 cm. Virtually all the marsh organisms living in the contaminated area were affected by the oil at least to the extent that they accumulated oil hydrocarbons in their tissues. Our data suggest that two processes may occur as the oil passes through the marsh ecosystem. There may be a progressive loss in the straight chain hydrocarbons in relation to branched chain, cyclic and aromatic hydrocarbons. There also appears to be a selection for the higher boiling fractions of the contaminants higher up the food chain.

    Notes: Abstract This study was undertaken to assess the impact of current land use practices, to provide data on which to base recommendations for petroleum discharge regulations, and to develop reliable methods for monitoring hydrocarbon pollution in Victorian coastal waters. Analyses of sediments and mussels were used to identify areas of chronic contamination and probable sources. A mussel transplant experiment detailed the movement of major industrial effluents. Petroleum hydrocarbons varied from non-detectable to maximum values of 30 mg/g lipid in areas near points of continuous discharge. Problem areas were identified where tissue levels of hydrocarbons in mussels consistently exceeded 4 mg/g lipid and petroleum buildup was evident in sediments. Differences in chemical composition of hydrocarbons in various ecosystem components reflected biogeochemical processes acting to disperse, degrade, and transport hydrocarbons discharged into coastal waters. Results showed Port Phillip Bay is subject to much larger and more complex discharges of petroleum-containing wastes than Western Port from both discrete ship and shore-based inputs and from diffuse urban/industrial inputs, including surface run-off and atmospheric precipitation.

    Notes: Abstract Several truckloads of mixed waste oil were dumped onto a short section of road and into the intertidal wetlands near Cairns, Queensland in January, 1994. The oil contaminated a band of mangroves 15–44 m wide along approximately 200 m of road. Impacted marsh included Melaleuca forest and high-intertidal mangroves. The initial concentrations of petroleum hydrocarbons in surface sediments reached 17% of the dry weight in heavily impacted areas. These high concentrations observed in limited spatial areas were similar to those observed over large spatial areas after a catastrophic oil spill in Panama in 1986. No large scale biological damage was observed from this localised spill. Clean up efforts and natural dissipation processes reduced sediment hydrocarbon loads to non-acutely toxic levels in 1.5 years in the intertidal mangroves. High hydrocarbon concentrations remained in the Melaleuca sediments for at least two years post spill. Internal molecular markers were used to detail hydrocarbon dissipation and degradation rates. This study provides a contrast between impacts of localised versus catastrophic oil spills in tropical mangrove habitats.

    Description: As part of the NOAA/ROPME/MSRC sponsored assessment of the coast of Saudi Arabia, heavily impacted by the large oil spills of the 1991 Gulf War, we measured benthic community respiration (R) and primary production (P) rates in shallow subtidal basins near heavily oiled coastlines. Study sites were located in zones predicted to be basins of maximum deposition of any oiled sediments likely to wash off the adjacent coast and in reference bays predicted to be clean and unaffected. We measured oxygen exchange using in situ benthic respirometers and analysed petroleum hydrocarbon (PHC) levels in the near surface sediments at five stations. We concentrated our efforts in mud habitats to complement related studies in seagrass habitats. Measured community R rates ranged from a low of 700 μM m2 h−1 in coarse sand sediments with total organic carbon content (TOC) of only 0.16% of dry wt to the highest rate of 2184 μm m−2 h−1 in finer mud-sand habitats with 0.39% TOC. All measured rates were in the range of literature values for shallow marine sediments at temperatures of 17 to 19°C. Sediment oil content was 13–540 μg g−1 dry wt by ultraviolet fluorescence (UVF) analysis and 0.5–103 μg g−1 by gas chromatography (GC). Benthic P rates, calculated as light minus dark changes in dissolved oxygen, ranged from a low of 1162 μm m−2 h−1 at the most heavily oiled site to a high of 5216 μm m−2 h−1 at less oiled sites. While a weak inverse relationship between benthic P and sediment oil content was not significant statistically due to the small number of samples, a significant inverse relationship was found between the ratio of production to respiration (P/R) and the total petroleum content of the sediments by UVF. The effect appears to be driven more by differences in production than an effect on respiration which showed little relationship with either oil content or productivity. We conclude that within 1 year after the oil grounded on the intertidal sands of Saudi Arabia, the levels of oil in subtidal benthic sediments had decreased in most habitats to levels that did not show community stress by our oxygen measurements. Rather, long term damage to benthic subtidal habitats was limited only to enclosed bays adjacent to the most heavily oiled coastlines. Preliminary estimates of yearly P converted to carbon units indicates that the shallow mud sediments of the Gulf are at least as productive as most oligotrophic water columns. Since benthic habitats covered by seagrass, algae beds or coral reefs are likely to have even higher production rates, we conclude that benthic processes contribute significantly to the overall carbon flux in the Gulf ecosystem.

    Description: Saudi Arabian coastal waters near sandy beaches, severely contaminated with crude oil released in Kuwait during the 1991 Gulf War, as well as underlying sediments and a few bivalves, were analysed to assess concentrations and composition of petrogenic hydrocarbon mixtures and structurally related oxidation products. Concentrations of dissolved oil residues determined by UV spectrofluorometry (UVF) near oil deposits on beaches did not exceed 3.5 μg l−1; concentrations dropped to approximately 1/10th of this value a few miles offshore. Gravimetric concentrations of unfractionated lipophilic material extracted from large volumes of seawater at the same stations were up to 10 times those determined by UVF. After chromatography on silica gel, individual petroleum hydrocarbons in the low polarity fractions and oxidation products in the polar fractions were characterized by their spectra (GC/MS) and quantitated by Selected Ion Monitoring (SIM) GC/MS. Concentrations of oxidation products (ketones, aldehydes, alcohols) of aromatic hydrocarbons exceeded those of their parent compounds by more than an order of magnitude. Significant concentrations were also found of the presumably pyrogenic triplett sensitizer anthraquinone. Contributions to polar fractions of water extracts by biosynthesized lipids were negligible. UVF determinations appear to underestimate concentrations of dissolved oil residues, because many oxidation products have lower fluorescence quantum yields than the respective parent hydrocarbons. Their ecotoxicological properties are unknown. Concentrations measured in sediments by UVF ranged from 13 to 540 μg g−1 dry wt and 0.5 to 103 μg g−1 as measured by gas chromatography with flame ionization detection (FID GC). Bivalves ranged from 0.8 to 1.5 μg mg−1 extractable organic matter (EOM) by UVF, and 0.1 to 0.3 μg mg−1 EOM by GC analysis. PAHs were identified in sediment and bivalve extracts by GC/MS and quantitated by SIM GC/MS. None of the relatively water soluble alkylbenzene photo-oxidation products found in water samples nor any higher molecular weight quinones could be detected in sediment extracts. However, ion chromatograms strongly suggest the presence of numerous high molecular weight aromatics in that matrix.

    Description: Oil released into the sea undergoes immediate compositional changes as a result of processes of volatilization, dissolution, particle adsorption, and microbial and photochemical decomposition. Based on our observation of the molecular composition of oil residues dissolved in subtropical ocean waters, we hypothesized photo-oxidation of alkyl-substituted polycyclic aromatic hydrocarbons (PAH) and heterocyclic aromatics in preference to their unsubstituted parent compounds. As the ratios of alkyl to parent PAH are used to assign sources to contaminant residues in environmental samples, we tested the hypothesis in a controlled experiment: membrane-filtered seawater collected near the island of Bermuda was saturated with a Nigerian crude oil and exposed to natural sunlight in a quartz flask. Comparison with a dark control under otherwise identical conditions served to differentiate between sunlight-induced and microbially mediated decreases in concentration and changes in composition. We conclude on the basis of UV fluorescence, GC-MS, and microbiological data that sunlight-induced oxidation is responsible for the rapid loss of the UV fluorescence signal for total aromatic hydrocarbons and for the preferential depletion of the alkyl-substituted PAH and heterocyclic aromatics. Structure-dependent selectivity in the photo-oxidation of dissolved oil residues may thus result in residual hydrocarbon blends which could be mistaken as originating from incomplete combustion processes.
