Sentence examples for marsh sediments were from inspiring English sources

The PCA results showed that PAHs in marsh sediments were primarily pyrogenic, while PAHs in shelf sediments were primarily petrogenic.

The bioavailable proportions of PAHs in marsh sediments were generally > 0.02%, higher than those in shelf sediments.

Shelf sediments were collected during the Deepwater Horizon oil spill and marsh sediments were collected two years after the spill, so hydrocarbon contamination might be expected.

For example, high-molecular-weight PAHs were found to be more abundant in finer than coarser fractions after salt marsh sediments were size-fractionated [59].

Based on diagnostic ratios of PAH isomers and principal component analysis, shelf sediment PAHs were petrogenic and those from marsh sediments were pyrogenic.

In contrast, surface areas in marsh sediments were lower and were more variable, as expected from the coarser grains, ranging from 0.9 to 8.2 m2 g−1.

Intertidal salt marsh sediments are extraordinarily complex environments that display extremely high temporal and spatial variabilities.

Simultaneously, intertidal salt marsh sediments are highly bioturbated, especially by fiddler crabs and polychaetes [14, 15].

Concentrations of PAHs did not correlate with specific surface area over all stations, but they did correlate well if only the marsh sediments are considered (R = 0.70, p < 0.01, Figure 6).

Using a measured O2 flux of 68 89 mmol O2 m-2 d-1 yields O2 penetration depth values between approximately 0.2 mm and 1.0 mm.[72] Given that the marsh sediments are periodically exposed to the atmosphere, an value of 1.0 mm is used in this study, which results in values that vary from 4.1 to 17.0 mm.

On the other hand, early-diagenetic remobilization of Fe and Mn in organic rich marsh sediment is a common phenomenon.
