ABOUT THE LIBRARY
The LUMCON Library collection was originally housed in Ellender Memorial Library, located at Nicholls State University in Thibodaux, Louisiana. After completion of the DeFelice Marine Center in 1986, the collection was moved to its present location. Since that time, the Library has become an active resource center for LUMCON faculty and staff as well as Consortium member institutions, visiting researchers, students, and the public.
The library contains a computer lab and several study spaces available to visiting students, scientists, or groups (such as attendees of a writing retreat).
The collection and development of library materials reflects LUMCON’s research programs. The collection has approximately:
- 4,600 monographs
- 5,800 bound volumes
- 200 journal titles
- 26 current journal subscriptions
- 850 maps
- 35 atlases
- 3,600 government documents

INTERNSHIP PROGRAM
The LUMCON Library is available as an internship site for graduate-level students who have completed at least two semesters toward a Master’s degree in Library and Information Science. Applications will be accepted on a continuing basis and internships may be completed during any semester. Prior library experience or an undergraduate degree in science is desirable, but not necessary. Credits will be awarded based on the number of person-hours completed (40 person-hours per credit hour).
The internship will consist of both field experience, encompassing many operations of a special library, and a special project in technical services. The Librarian will give the intern an overview of reference services, technical services, library administration, and budgeting, and will guide the intern through special projects. The LUMCON Library uses SIRSI/Dynix’s Symphony Integrated Library System as well as OCLC for Cataloging/Interlibrary Loan services.
Contact the Librarian for more information or to apply for an internship.

DISPERSANTS BIBLIOGRAPHY
Evaluating the value of using dispersants or in situ burning in various regions of the United States requires an estimate of how often such technology might reasonably be considered. This study collected information on marine oil spills of 1000 barrels or more occurring in the coastal and offshore waters of the Unites States (excluding Alaska) from 1973 through June 1994. Each incident was examined using criteria for oil type, weather conditions, water depth, and distance from the shoreline. This allowed the frequency and geographic distribution of dispersible and burnable spills to be estimated. The effect of modifying the criteria on the frequency distribution of dispersible and burnable spills was evaluated. Data were obtained on 138 refined product and 69 crude oil spills. The majority of these spills occurred in shallow water, close to the shoreline, and/or close to a sensitive receptor. Depending on the severity of the criteria, between 10% and 51% of the crude oil spills and 4% and 18% of the refined oil spills studied were realistic candidates for dispersant use. Between 35% and 58% of the crude and 22% and 38% of the refined oil spills were realistic candidates for burning
Lethal limits for 14 oil-emulsifying agents were established for a range of concentrations between 0.001 and 0.1 ml/l. Different reactions were noted between concentrations in freshwater and seawater. Crude oil alone was found to be less detrimental to organisms than a mixture of crude and emulsifying agents
Experiments are reported on the effects of dissolved and dispersed crude oils (from Venezuela, Iran, and Libya) on various stages of cod eggs and young larvae of cod, herring, and plaice. Results, which varied widely depending on the type of oil, showed that the mortality of the eggs was proportional to the concentration of dissolved substances up to a certain limit, the eggs were most sensitive during the first 3 days of their development, and the 10 day-old embryos showed no greater mortality than the controls. Even with concentrations sub-lethal to eggs, many larvae that hatched showed abnormalities and could hardly survive. Larvae were more sensitive than embryos and after a critical point was reached there was no recovery in clean water; the 'mean critical time' taken to reach this point was used to compare the toxicity of different oils. Dispersions were 10-100 times more toxic than a floating hydrocarbon pollutant of the same volume and the toxicity of a dispersion increased and persisted longer when prepared with a dispersing agent not in itself toxic. The larvae appeared to be incapable of detecting and avoiding hydrocarbon dispersions, the chemoreceptors becoming blocked very quickly on the first contact
A planktonic dinoflagellate was observed in growth studies while being exposed to a range of surfactant types. Anionic surfactants had more harmful effects compared with cationic and nonionic surfactants. Among the effects from anionic surfactant exposure included negative effects on initial response, growth rates, and maximum cell numbers. The least toxic surfactant tested was used in further tests to establish correlation between growth constant and maximum cell number with concentrations of surfactant in seawater. Mortality rates were noted in treated and non-treated samples
Microbially produced biosurfactants were studied to enhance crude oil desorption and mobilization in model soil column systems. The ability of biosurfactants from Rhodococcus rubber to remove the oil from the soil core was 1.4–2.3 times greater than that of a synthetic surfactant of suitable properties, Tween 60. Biosurfactant-enhanced oil mobilization was temperature-related, and it was slower at 15 °C than at 22–28 °C. Mathematical modelling using a one-dimensional filtration model was applied to simulate the process of oil penetration through a soil column in the presence of (bio)surfactants. A strong positive correlation (R2=0.99) was found between surfactant penetration through oil-contaminated soil and oil removal activity. Biosurfactant was less adsorbed to soil components than synthetic surfactant, thus rapidly penetrating through the soil column and effectively removing 65–82% of crude oil. Chemical analysis showed that crude oil removed by biosurfactant contained a lower proportion of high-molecular-weight paraffins and asphaltenes, the most nonbiodegradable compounds, compared to initial oil composition. This result suggests that oil mobilized by biosurfactants could be easily biodegraded by soil bacteria. Rhodococcus biosurfactants can be used for in situ remediation of oil-contaminated soils
The toxic effects of oil dispersants have been investigated in many different test organisms. In the present investigation induction of rapid lysis mutants in bacteriophage T4D was used as a tool for measuring any possible mutagenic effect of Corexit 9527, Corexit 9550, Finasol OSR-4, OSR-5, OSR-7, BP1100, OSD 41, Dispolen 345 and Hexol 6141 in this organism
Biofouling communities (groups of encrusting organisms) growing on Plexiglas plates were selected as bioindicators to evaluate the effects of a simulated dispersed crude oil spill. Results showed significant changes in the number of taxa, abundance, and percentage of substrate cover between treated and control groups; however, these effects represent a relatively low biological impact produced by the dispersed oil. The overall conclusion is that biofouling has a high recovery capacity despite an actual acute disturbance, since many biofouling organisms showed a significant resistance to the effects of dispersed crude oil
An experimental ecosystem, consisting of a compartmentalized device capable of holding 560 liters of water in a field setting, was tested for its ability to be used to determine effects of pollutants on plankton and copepods. 40 mg/l concentrations of anti-petroleum products, including one of the Corexit family of dispersants, was added to the device while photosynthetic activity, chlorophyll a concentrations, and plankton dry weight were used to establish effects on organisms. Corexit was found to produce weak and transitory changes during the 15-day trials
Anti-petroleum products, including Gamasol--used extensively in the Torrey Canyon incident--were introduced into micro-communities of benthic diatoms in controlled ecosystem experiments. 30-minute exposure to Gamasol at 40 mg/l concentrations led to complete destruction of the diatom community
Petroleum products discharged at the water surface are rapidly modified under the effect of physico chemical and biological transformations, themselves closely dependent on ecological factors. The role of some of these, such as illumination, may be particularly significant. This report deals with the effect of this parameter on the phytotoxicity of Kuwait crude oil on the primary production of a microalga (Phaeodactylum tricornutum) and marine plankton communities. The result of these investigations indicates that the toxicity of extracts made from a crude oil is about two to three times greater when the latter is previously subjected to illumination of sufficient intensity and duration. The incorporation of a chemical dispersant (Corexit 8666) magnifies this phenomenon. In the case of a weathered crude oil mixed in equal parts with the dispersant, illumination raises the toxicity of the extracts by a factor of about 30
Authors report on Swedish laws enacted regarding oil discharges into territorial waters and the means of controlling spilled oil. Also mentioned is a program between public and private sectors to combat spills. This paper also reports on the progress of studies carried out in support of the program such as dispersant and oil/dispersant toxicities in brackish waters, the fate and effects of oil in various ecosystems, as well as other investigations
Field and laboratory studies on the toxicities to mangroves and associated biota of undispersed and chemically dispersed oils are being conducted in Malaysia. Results to date show the following: 1) Most of the oils, both undispersed and dispersed, affect mainly the young Avicennia with heights less than 180 cm in the field. Toxicity to older saplings is less acute. 2) There appear to be few differences in the impact of oils on Avicennia saplings due to tides. 3) When the toxicities of dispersed and undispersed Arab light crude were compared, the following observations were made: most tests show either no significant differences between undispersed and dispersed oils or that undispersed crude is more toxic than dispersed crude, while a small percent show that dispersed crude is more toxic than undispersed crude. 4) When the toxicities of oil types, namely Bunker C, Malaysian crude, and Arab light crude to the saplings were compared, it was found that Bunker C was the least toxic, followed first by the Arab light and then the Malaysian crudes. 5) Growth of the commercially important tiger prawn introduced into a flowthrough system four months after an oil spill appeared normal. These animals compared well with those reared in oil-free tanks and those cultured in situ in ponds. 6) Most of the mortality of saplings was probably due to passive surface deposition as well as active uptake. The main accumulation site was leaf tissue as evidenced by GC analysis
Two types of fluorometer were tested for their ability to 1) measure real-time oil-in-water concentrations, 2) compare the results against data from other procedures, and 3) to be used in conjunction with other laboratory analysis to better understand the connection between fluorescent signal and chemical composition of oils. For these tests, Corexit 9500 was used, as well as eight oils, including crude, diesel fuel, and fuel oil
A comprehensive study was conducted with two flow-through fluorometer models made by Turner Instrument (10 AU and 10). This was undertaken to evaluate their ability to 1) measure real-time oil-in-water concentrations, 2) to compare results to other total petroleum hydrocarbon (TPH) procedures, and 3) to carry out supporting laboratory analysis to help explain the relationship of the fluorescence to the chemical composition in oils. The model 10 AU was equipped with a long wavelength optical kit for crude oils while the model 10 was equipped with a short wavelength optical kit for diesel fuels and light refined oil products. Eight oils and Corexit 9500 were used for the tests
A number of weathered crude oil and chemical dispersant (Corexit 9527) spills were made experimentally in an Atlantic coast salt marsh during the summer of 1986. The intent of the spills was to measure the extent of damage and recovery potential of affected marsh vegetation, principally Spartina alterniflora and S. patens. Treatments included control, oil dispersant, and oil with dispersant applied in three vegetation zones (creek edge, midmarsh, and high marsh). S. alterniflora dominated in the first two zones and S. patens in the third. Measurements were made of plant height, stem density, flowering success, biomass, and other visually discernable characteristics. The study was complemented by laboratory investigations on samples of marsh maintained with sea water exposures in a greenhouse. Although the results represent only one season’s observations, some general trends in response to treatments have become apparent. The midmarsh S. alterniflora community was found to be the most sensitive to oil and dispersant applications, but within this system, oil treatment had the least impact. Dispersant alone and the oil with dispersant treatments had similar impacts. The second most sensitive community was the creek edge. Impacts within this community were much less pronounced than those observed in the midmarsh community. Dispersant and oil with dispersant treatments had the greatest impacts and were similar in severity. The oil treatment had little impact. The high marsh community was generally the least sensitive of the three marsh vegetation zones. None of the treatments appeared to cause much damage, and all treatments induced approximately the same impacts. No recovery from the impacts was observed in this first season
Corexit 9500 was added to Arabian medium crude oil-contaminated wetland sediment slurries to observe changes in respirometric activity by oil-degrading aerobic bacteria. The addition of dispersant was shown to elevate respirometric activity in the microbial populations, although remaining total target saturates were substantially higher in dispersant-amended slurries. There was no change in aromatics after the addition of Corexit 9400, implying that the dispersant acted as competitive substrate rather than enhancing degradation of crude oil
Redox potentials and sediment porewater parameters were measured around the periphery of a small cove along the San Jacinto River in Texas throughout a crude oil and chemical dispersant remediation study to distinguish normal dynamics from those caused as a response to stress from oil deposition and chemical treatment and subsequent recovery. Before the application of oil and treatments, sediments displayed average redox potentials of 0–350 mV when not submerged. Within 2 days of the applications, redox potentials in these plots decreased and exhibited a range from −200 to 0 mV for a duration of 5 weeks. Applied treatments significantly reduced the sediments of the wetland. Reduced redox potentials were indicative of the corresponding sulfate reduction that was also found to be significant following the oil application. GC/MS and MPN analysis indicates this reduction is due to biological oxidation of the crude oil components by alkane- and PAH-degraders in these surficial sediments and validates the usefulness of the redox measurement as an indicator for carbon oxidation. Increases in aqueous phase total organic and inorganic carbon coincided with a decrease in pH shortly after the applications, suggesting incomplete mineralization and the generation of organic acids. While dissolved ferrous iron and sulfide have been found to be good indicators of reductive processes in petroleum-contaminated aquifer sediments; that was not the case in this wetland study. Despite the disappearance of sulfate following the oil application, dissolved ferrous iron and sulfide concentrations remained at pre-application levels suggesting the formation of mackinawite and/or pyrite. The transient exposure of surface sediments to oxygen complicates the consideration of potential solid phase pathways since aqueous iron may be removed by precipitation when oxidized or reduced, making porewater iron a poor indicator for terminal electron accepting processes in wetland sediments
Chemical dispersants for combatting oil spills increasingly are being recognized as a most valuable addition to the available means for damage prevention and cleanup. A study of oil spill cleanup costs enables one to apply a most useful perspective to the issue of costs. Based on public information sources where costs were reported for cleanup of oil that impacted a shoreline, mechanical methods ranged in cost from a minimum of $65 per barrel of oil to a maximum of $5000 per barrel. In contrast, costs for intercepting the oil at sea by spraying dispersant from four-engine fixed wing aircraft ranged between a minimum of $15 per barrel of oil treated up to a maximum of $60 per barrel of oil treated. The study spill sizes were 10 000 to 100 000 barrels of oil
Median tolerance limit for 24 hours for the glass fish Ambassis sp. was 1.04 ml Corexit per liter of sea water without crude oil and 1.07 ml/l with crude oil. The corresponding figures for palaemonid shrimps appeared to be 2.08 and 1.68 ml/l, respectively. Threshold toxicity for the glass fish was raised from 0.12 ml to 0.51 ml/l after the addition of crude oil; for the shrimps, there was only a slight raise from 0.12 to 0.21 ml/l. Percentage survival of test animals in inversely proportional to the concentration of Esso Corexit, it shows a negative exponential relationship with concentration. For the glass fish, the joint effect of Esso Corexit 7664 and crude oil considered as a whole proves to be less toxic than the lone effect of the dispersant at lower concentrations and more toxic at higher concentrations. For palaemonid shrimps, toxicity of Corexit is reinforced at higher and lower concentrations. The shrimps could tolerate the dispersant better than the glass fish. Finally, Esso Corexit is found to be much less toxic than other emulsifiers tested
The development of dispersant use guidelines and decision making criteria are complex interagency activities. The use of dispersants as an oil spill response option in United States' waters occur as the result of a decision process established by the National Contingency Plan (NCP), a federal regulation. The NCP requires a recommendation from the federal predesignated On-Scene Coordinator (OSC) to the U.S. environmental Protection Agency (EPA) representative to the Regional Response Team (RRT). The recommendation is simultaneously made to State RRT representative(s) whenever state(s') waters are affected. The approval necessary for dispersant use is concurrence with the OSC's recommendation by the EPA RRT representative and, as appropriate, the State RRT representative(s). The U.S. Departments of Commerce (DOC) and the Interior (DOI) have related authorities and are also RRT member agencies. The NCP recommends that EPA and state RRT representatives consult with their DOC and DOI counterparts, as appropriate, during the decision process. Such consultation may become mandatory following a pending revision of the NCP, and where federal trusteeship interests are involved
The effect of the oil-spill dispersant Corexit 9527 on egg-hatching rate of Macrobrachium rosenbergii (de Man) was studied by using an innovated flow-through bioassay technique. This bioassay method relies on the fact that M. rosenbergii fertilized eggs when detached from the mother prawn were able to hatch artificially. The flow-through system generated a stable and good water quality environment for hatching the eggs successfully. The Corexit 9527 had a pronounced effect on hatching rate of the M. rosenbergii eggs. In the control, the hatching rate of the eggs was 95·55% ± 1·74%. However, it was reduced drastically with increasing concentrations of Corexit 9527. A 100% inhibition of egg hatchability was found when the level of Corexit 9527 was higher than 250 mg litre-1. The EC50 and the EC95 values estimated by the probit method were 80·4 ± 5·5 mg litre-1 and 193·5 ± 39·9 mg litre-1 respectively (P = 0·05). The recommended safety level of Corexit 9527 for M. rosenbergii in Malaysian estuarine waters is below 40 mg litre-1
This report focuses on the establishment and subsequent lifting of fishing restrictions and the effects of the Sea Empress spill and dispersant application on fish and shellfish in Milford Haven. Overall, effects of the spill were less severe than would have been expected given the quantity of oil released
The tanker “Sea Empress” grounded at the entrance to Milford Haven in February 1996, releasing 72 000 t of Forties blend crude oil and 480 t of heavy fuel oil into the waters of southwest Wales. An estimated 15 000 t of emulsified oil came ashore along 200 km of coastline. A fishery exclusion zone was established to protect consumers of fish and shellfish, and monitoring was instigated in order to establish the degree and spread of contamination. A wide range of further studies were conducted with the aim of assessing the overall impact of the spill. In this paper we report on the establishment and subsequent lifting of fishing restrictions and the results of the fish and shellfish monitoring programme. The application of a range of biological effects techniques which illustrated sublethal impacts is also described. In retrospect, the impact of the spill was much less than would have been expected from the quantity of oil spilled. This was due to the circumstances of the spill, which led to fresh crude oil, amenable to chemical dispersion, being released during each ebb tide and carried into deep water to the south of Milford Haven. This enabled the extensive dispersant spraying operation, which included the aerial application of 446 t of chemical oil dispersant in order to enhance the rate of natural dispersion of the oil. This reduced the impact of the spill by preventing an additional 57 000 to 110 000 t of emulsified oil from impacting the beaches
The various factors affecting the performance of oil spill dispersants have been studied in the laboratory using a simple test to emulsify the oil in the water. The observations have been confirmed by spraying oil onto the sea followed by overspraying with dispersant. It was found that viscosity of the oil or mousse was the main limitation that influenced the droplet size distribution. Energy of agitation had a minor effect but there was no evidence that the “self-mix” dispersants required less energy for adequate dispersion
The response of marine bacteria to Corexit 9527, with and without Prudhoe Bay crude oil labeled with n-(1-14C)hexadecane, in a temperate pelagic environment was monitored over 22 days using controlled ecosystem enclosures. The results indicated that Corexit and Corexit-dispersed crude oil stimulated bacterial production by serving as substrates and/or by inducing the release of organic compounds from the indigenous phytoplankton population. Highest bacterial standing stock was observed in the enclosure treated with a mixture of Corexit and crude oil, in which a large fraction of the predominant bacterivores were eliminated. Biodegradation appeared to be more significant than abiotic processes in contributing to the loss of low volatility n-alkanes in Corexit-dispersed oil
The droplet size distribution of oil-in-sea-water emulsions produced by the action of concentrate dispersants were obtained using a Coulter Counter Model TAII. Studies were made of the droplet size distributions obtained using five oils of varying viscosity which were treated with six different concentrate dispersants. The work showed that the technique can be used to assess dispersant performance and that there is a relationship between droplet size distribution and dispersant efficiency
