TL;DR: Orihel et al. as discussed by the authors studied the methylmercury (MeHg) concentration and production rates in bottom sediments along the mainstem of Chesapeake Bay and on the adjoining continental shelf and slope.

TL;DR: It is found that methylation rates are the highest at locations with high Hg content (relative to carbon), and that organic matter does not hinder mercury methylation in estuaries.

TL;DR: The results across a broad gradient of sites demonstrate that the pathways of MeHg to lower trophic level estuarine organisms are distinctly different between benthic deposit feeders and forage fish, suggesting that even in systems with contaminated sediments, transfer of Mehg into estuarist food webs maybe driven more by the efficiency of processes that determine MeHG input and bioavailability in the water column.

TL;DR: In this article, a detailed study of the biogeochemical factors controlling mercury distribution, methylmercury (MeHg) production, and MeHg efflux in sediments of the mid-Atlantic continental shelf and slope was presented.

TL;DR: In this paper, the effects of major disturbances on the biogeochemical cycling of Hg in coastal systems were investigated. And the authors estimate that the two hurricanes redistributed approximately 5 times the annual Hg input from the Mississippi-Atchafalaya River system and atmospheric deposition.
