- W2005574610 abstract "ABSTRACT Surficial and subsurface (10–13 cm) sediment samples were taken at 7 stations (17 cores) on the northern margin of the Bermuda seamount, remote from ship traffic, beaches, and atmospheric fallout from aircraft. Their aliphatic (pentane-extractable) hydrocarbon content was found to be very low, comparable to samples from the North Atlantic abyssal plain, and two orders of magnitude lower than for typical coastal samples. About half of the aliphatic hydrocarbons are clearly biogenic, and the remainder are characteristic of petroleum residues. Petroleum hydrocarbon concentrations are lower in subsurface (for example, 0.11 µg/g dry weight) than surface samples (0.47 µg/g), and are lower outside the reef (0.25 µg/g) than inside (0.47 µg/g). These results are quantitatively consistent with a diffusion model. Extremely rapid bioturbation or totally quiescent deposition on a stable sedimentary facies can probably be eliminated as hypotheses for the deposition and transport mechanism within the sediment. Whether degradation is important cannot be answered without further studies." @default.
