Fifty-three undisturbed sediment cores (1 m, 6·7cm diameter, i.d.) were collected from two intertidal sites — fine sand tidal flat (Patricia Bay, Vancouver Island; mean grain size 152 ± 29 μm (<em>n</em> = 15); permeability 0·124 cm min⁻¹) and a coarser sediment beach (Island View Beach, Vancouver Island; mean grain size 280 ± 142 μm (<em>n</em> = 3); permeability 0·435 cm min⁻¹). Thirty-three were used for oiling studies, 20 for granulometric determinations. A further 12 reconstituted cores were prepared from mixtures of Patricia Bay and Island View Beach sediments with fine clay added, to yield an overall range of mean sediment grain size (132 to 287 pm), mud content (0·35 to 4·7%), and permeability (0·0035 to 0·44 cm min⁻¹).</p><p>Known amounts of an experimentally weathered heavy oil (Alberta Sweet Mixed Blend) were layered onto water standing over the sediment cores during a simulated flood period, and during simulated ebb were brought into contact with the core surfaces, where the oil layer was left in contact for varying tidal periods.

Also investigated were the influence on oil penetration of sediment grain size, percentage mud content, and duration of tidal submersion.</p><p>Oil loading experiments with surface slicks of different thicknesses (0·5–10 mm) showed that increasing thicknesses of surface-applied oil resulted directly in increasing concentrations of hydrocarbons in the sediments.

Penetration was also influenced by tidal emergence, as indicated in experiments with different tidal regimes. The relationship was consistent.

Principal Component Analysis (PCA) of the a priori defined types of samples and on subsets of the total dataset show that there is a systematic difference in the pattern of naphthalenes in fish liver samples caught close to oil platforms and those caught at reference stations. Statistical analysis using ANOVA on each individual variable supports the multivariate interpretation. It is not possible to distinguish between the sets of platform samples from the different surveys. This suggests that the pattern of NPDs in fish liver does not depend on what type of drillmud is discharged from the platform and that there are only small differences in the analytical procedures between surveys. The results show that the livers of migratory fish caught close to oil platforms contain increased amounts of naphthalenes whereas the three-ring aromatic and the sulphur aromatic compounds are not accumulated significantly in the liver.</p></div>","PeriodicalId":100982,"journal":{"name":"Oil and Chemical Pollution","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1988-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/S0269-8579(88)80021-2","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77559145","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Particular attention isfocused on the dispersion of oil from the sea surface and its influence on spreading, the role of environmental data (currents, wind, temperature, ice conditions) used as input to the model, and the interaction of oil with a variety of shoreline types.
