TL;DR: This analysis suggests that while atmospheric deposition is the main source of inorganic Hg to open ocean systems, most of the CH₃Hg accumulating in ocean fish is derived from in situ production within the upper waters (<1000 m), and that the deeper waters of the oceans are responding slowly to changes in atmospheric Hg inputs.
Journal ArticleDOI
A global ocean inventory of anthropogenic mercury based on water column measurements

TL;DR: In this paper, the authors present an estimate of the total amount and spatial distribution of anthropogenic mercury in the global ocean based on oceanographic measurements of mercury and related parameters from several expeditions including data from recent GEOTRACES cruises.
Journal ArticleDOI
Geochemical Controls on the Production and Distribution of Methylmercury in Near-Shore Marine Sediments
TL;DR: Reductions in the organic content of coastal sediment, a potential result of nutrient abatement programs intended to inhibit eutrophication of near-shore waters, could enhance MMHg production by increasing the bioavailability of the large reservoir of "legacy Hg" buried within the sediment.
