“…However, during the following 8 months, which were in the wet season, biodegradation was observed only in the uppermost layer (0 to 5 cm) of sediment. This was probably a result of oxygen deprivation in the lower layers, because the soil was completely covered with water during this period (88). Overall, even the fertilized oil decomposed slowly, suggesting that oil contamination is likely to persist in mangrove soil.…”

“…During the first 3 months of the trial, which occurred toward the end of the dry season, the authors implied that the soil was exposed to the air regularly, although the length of time is not recorded (88). During this period, there was some evidence of enhanced oil biodegradation.…”

“…Posslbly the oil replaces the interstitial water contalnlng the electron acceptors, or there is a lack of some other factor such as iron or nutrient. The latter theory is strengthened by the work of Scherrer & Mille (1989) who reported that the slow biodegradation of oil trapped in peaty mangrove soils could be hastened by the addition of oleophilic fertilisers. In contrast, Mille et al (1988) investigated the relationship between the dissolved oxygen in overlying water and the degradation of various oils and pure hydrocarbons in sediment.…”

This paper reviews some of the field aspects of hydrocarbon bacteriology in the marine environment. The first section recapitulates the current position with regard to the input of polluting oil into the sea and the main environmental factors which govern the rate of oil breakdown. The second deals with the 1991 oil spill during the Gulf War and what is known about the bacteriology of that area, together with some recent data from Japan. Thirdly a critical review of the theory and practise of bioremediation as applied to contaminated beaches in several parts of the world leads to the conclusion that there are still a lot of unknown variables that must be better understood before the method can be of widespread use. Finally a short review of gaseous hydrocarbons in the sea suggests that methane from petrogenic or biogenic sources is of both practical and theoretical interest and importance for the future.

“…Compared to the major natural disturbances to shallow water Antarctic habitats, marine pollution around McMurdo Station covers a small area of the seafloor. However, recovery of native communities will require a much longer time if rates of hydrocarbon degradation and natural sedimentation are as low as expected (Scherrer and Mille 1989, Delille and Vaillant 1990, Leahy and Colwell 1990. Recovery at any rate will depend upon abatement of past dumping and disposal of anthropogenic chemicals and other wastes.…”

Sampling and field experiments were conducted from 1975 to 1990 to test how the structure of marine benthic communities around McMurdo Station, Antarctica varied with levels of anthropogenic contaminants in marine sediments. The structure of communities (e.g., infauna density, species composition, and life history characteristics) in contaminated and uncontaminated areas were compared with the structure of communities influenced by two large‐scale natural disturbances, anchor ice formation and uplift or iceberg scour. Benthic communities changed radically along a steep spatial gradient of anthropogenic hydrocarbon, metal, and PCB contamination around McMurdo Station. The heavily contaminated end of the gradient, Winter Quarters Bay, was low in infaunal and epifaunal abundance and was dominated by a few opportunistic species of polychaete worms, especially Capitella spp., Ophryotrocha claperedii, and Gyptis sp. These are relatively small and motile species. Closely related species live in organically enriched and anthropogenically disturbed sediments throughout temperate latitudes. The edge of the heavily contaminated bay, the transition area, contained several motile polychaete species with less opportunistic life histories, especially Tharyx sp. and Haploscoloplos kerguelensis. Uncontaminated sedimentary habitats harbored dense tube mats of infaunal animals numerically dominated by populations of polychaete worms, crustaceans, and a large suspension feeding bivalve. These species are generally large and relatively sessile, except for several crustacean species living among the tubes. Community patterns along the anthropogenic disturbance gradient were similar to community changes along a natural gradient of anchor ice disturbance. The same motile and opportunistic polychaete worms were most abundant where anchor ice freezing and uplift were most severe. The motile polychaetes, Tharyx sp., Haploscoloplos kerguelensis, and Polygordius sp., were abundant at the edge of the anchor ice disturbance zone. The undisturbed bottom harbored the same dense tube mat community and large bivalve population. Community changes along the anthropogenic disturbance gradient were also similar to colonization patterns into bottom areas gouged by icebergs. The most recent ice gouges along the east side of McMurdo Sound contained large numbers of the motile opportunistic polychaete worms. Ice gouges along the western sound contained more motile species of infauna compared to adjacent undisturbed bottoms with large numbers of tube‐dwelling infauna. Motile species were also the first to colonize experimental sediments placed on the sea floor for 6 yr. Although the community patterns around anthropogenic and natural disturbances were similar, particularly the motile and opportunistic species at heavily disturbed and marginal areas, the natural disturbances cover much greater areas of the sea floor around the entire Antarctic continent. On the other hand, recovery from chemical contamination is likely to take many more decades than recovery...
