TLDR
The vertical distributions of hydrocarbons in the bottom sediments showed concentration increases parelleling the urbanization of the Puget Sound basin, indicating an alteration of these hydrocarols within the water column or differential particle transport.Abstract:
Concentrations and vertical fluxes of total carbon, aliphatic hydrocarbons, and polycyclic aromatic hydrocarbons (PAH) were determined in suspended matter and the underlying sediments in the central main basin of Puget Sound, Washington Suspended matter was collected seasonally at four depths in the water column using sequential sampling traps The flux of PAH through the 50- and 100-m horizons accounted for 84% of the PAH accumulating in the underlying surface sediments The concentration of PAH in the suspended matter from these traps, however, was 3 times greater than the concentration of PAH in the surficial bottom sediments Laterally transported suspended matter in the bottom boundary layer is apparently diluting the PAH during sedimentation The flux of aliphatic hydrocarbons to the sediments was greater than the accumulation rate in the sediments, indicating an alteration of these hydrocarbons within the water column or differential particle transport The vertical distributions of hydrocarbons in the bottom sediments showed concentration increases parelleling the urbanization of the Puget Sound basin 30 referencesread more

TL;DR: In this paper, parent and alkyl PAHs were quantified in suspended particulates and sediments (345 samples) from the Fraser River system, British Columbia, Canada, and the best potential to distinguish natural and anthropogenic sources is exhibited by ratios of the principal mass 178, 202, 228 and 276 parent PAH, 1,7/2,6+1,7-DMP (dimethylphenanthrene), the phenanthrene/anthracene and fluoranthene/pyrene alkyal PAH series and several less commonly applied PA

Role of large particles in the transport of elements and organic compounds through the oceanic water column

TL;DR: The role of large detrital particles in the downward vertical mass flux in the sea has been investigated in a variety of sources, including sediment trap data as mentioned in this paper, and it has been shown that the relatively rare, large particles sinking through the water column are responsible for the majority of the downward mass flux.

Occurrence and possible sources of perylene in marine sediments-a review☆
TL;DR: A review of the occurrence of perylene in the marine sedimentary environment is presented in this article, where surface sediment and sediment cores predating modern anthropogenic pollution from different marine and lacustrine locations and also peat samples from various regions of the world have been analyzed for perylene.

Organic matter sources to the water column and surficial sediments of a marine bay
TL;DR: Sediment trap and net plankton samples were collected monthly for a year at three depths in a marine bay (Dabob Bay, Washington). These materials and subsamples from a sediment box core were analyzed for lignin oxidation products as well as elemental and stable carbon isotope compositions as mentioned in this paper.
