“…2) corresponds with a dual, partly AOM-related, origin of this hydrocarbon (Thiel et al, 2001). Perylene, which is thought to originate from both terrestrial and aquatic organic matter during diagenesis (Silliman et al, 2000), is presumably derived from allochthonous sources. The stable carbon isotope signature with values as low as -45.80‰ PDB clearly characterizes the carbonates of the gray micrite as methane-derived.…”

Abstract. Methane-related carbonates from Hydrate Ridge typically show several macroscopically distinguishable mineral phases, namely whitish aragonite, lucent aragonite, and gray micrite. The relationship of these phases to particular microorganisms or biogeochemical processes is as yet unclear. We used a miniaturized biomarker technique on mg samples, combined with factor analysis and subsequent electron microprobe analysis, to study lipid biomarkers and chemical compositions of the individual phases. This allows us to identify particular mechanisms involved in the formation of the different carbonate precipitates. Our combined analysis of biomarkers and petrographic traits shows that most of the lipids related to the anaerobic oxidation of methane (>90% by weight) are concentrated within only a minor compartment (∼20% by volume) of the Hydrate Ridge carbonates, the whitish aragonite. The patterns indicate that the whitish aragonite represents fossilized biofilms of methanotrophic consortia containing mainly archaea of the ANME-2 group and sulfate reducing bacteria, whereas the precipitation of the lucent aragonite may have lacked the immediate proximity of microorganisms during formation. By contrast, the gray micrite formed by incorporation of allochthonous organic and inorganic matter during carbonate precipitation induced by the anaerobic oxidation of methane involving ANME-1 archaea.

“…According to Tisser and Saliot (1981), a Per content of more than 10% indicates a diagenic process. In the temperate topsoil, this compound may be from pyrolysis of the fossil fuels (Wilcke et al, 2002) while in soils/sediments (not in very surface) Per is mostly derived from nature diagenesis process (Silliman et al, 1998(Silliman et al, , 2000. Vertical profile of Per concentration in a sediment core was completely different from that of other PAHs concentration in the same core (Meyers and Ishiwatari, 1993).…”

“…PAH's are widely distributed in the air, water, sediments, and living organisms throughout the world (Aizenshtat, 1973;LaFlamme & Hites, 1978;Wakeham, Schaffner, & Giger, 1980;Coates, Connel, Bordero, Miller, & Back, 1986;Kennicutt, Sericano, Wade, Alcazar, & Brooks, 1987;Lamparczyk, Ochocka, Gryzbowski, Halkiewicz, & Radecki, 1988;El-Sikaily, Khaled, Nemr, Said, & Abd-Alla, 2003;Olson, Iverson, Edward, & Schroeder, 2003). Early studies determined that some compounds, such as perylene, retene, and permethrin, may be derived through the digenesis of biogenetic precursors, while most other PAHs are introduced into the atmosphere via incomplete combustion of fuels, industrial activities, accidental oil spills, and natural oil seepage (National Academy of Science, 1972;Lee, Prado, Howard, & Heits, 1977;Wakeham et al, 1980;Tan & Heit, 1981;Gschwend & Hites, 1981;Silliman et al, 2000). Concentrations of these compounds have been increasing throughout the last century due to enhanced anthropogenic activities such as industrialization, oil and natural gas exploration, etc.…”

Sediment and coral (Leptogorgia setacea) samples were analyzed for polycyclic aromatic hydrocarbon (PAH) concentrations along the Port Aransas Jetties off the coast of south Texas. Total PAH concentrations ranged from 243-2121 ppm in corals and from 1-328 ppm in sediments. In addition to total PAH concentrations being higher in coral samples, most of the corals also showed higher PAH concentrations in their skeletal cores than their body tissues. Our results suggest that corals are bioaccumulating PAHs. However, more statistical analysis and a larger breadth of samples need to be collected for better resolution. The importance of our observations is that the general trends show bioaccumulation at the beginning of the food chain (i.e., coral) which can have perilous consequences for bivalves, fish, and other organisms that feed in/on and around corals.
