Anthropogenic mercury migration from Asia to the open ocean Open
To evaluate the path of anthropogenic mercury (Hg) from Asia to the Pacific Ocean, we report mercury stable isotopes in zooplankton from the East China Sea to the Bay of Bengal, and in the Philippine Sea and the Central Pacific. Here, we f…

Particulate mercury export in the Central Pacific Ocean using 234Th238U disequilibria Open
Mercury (Hg) is a potent neurotoxin that enters the food web and may contaminate commercial, recreational, subsistence, and ceremonial fish stocks. Understanding the pathways by which this contamination occurs in marine systems is thus an …

Use of Stable Mercury Isotopes to Assess Mercury and Methylmercury Transformation and Transport across Critical Interfaces from the Molecular to the Watershed Scale (Final Report) Open
This project titled “Use of Stable Mercury Isotopes to Assess Mercury and Methylmercury Transformation and Transport across Critical Interfaces from the Molecular to the Watershed Scale” represents a collaborative effort between the Univer…

Mercury isotopic evidence for the importance of particles as a source of mercury to marine organisms Open
The origin of methylmercury in pelagic fish remains unclear, with many unanswered questions regarding the production and degradation of this neurotoxin in the water column. We used mercury (Hg) stable isotope ratios of marine particles and…

Mercury abundance and isotopic composition indicate subaerial volcanism prior to the end-Archean “whiff” of oxygen Open
Significance Earth’s atmosphere became oxygenated around 2.4 billion years ago, and this event was preceded by at least one short-lived “whiff” of free O 2 gas nearly 100 million years earlier. The cause of this whiff has so far been diffi…

A pulse of mercury and major ions in snowmelt runoff from a small Arctic Alaska watershed Open
Atmospheric mercury (Hg) is deposited to Polar Regions during springtime atmospheric mercury depletion events (AMDEs) that require halogens and snow or ice surfaces. The fate of this Hg during and following snowmelt is largely unknown. We …

Mercury isotopes reveal atmospheric gaseous mercury deposition directly to the Arctic coastal snowpack Open
Springtime atmospheric mercury depletion events (AMDEs) lead to snow with elevated mercury concentrations (>200 ng Hg/L) in the Arctic and Antarctic. During AMDEs gaseous elemental mercury (GEM) is photochemically oxidized by halogens to r…

Increased carbon capture by a silicate-treated forested watershed affected by acid deposition Open
Meeting internationally agreed-upon climate targets requires carbon dioxide removal (CDR) strategies coupled with an urgent phase-down of fossil fuel emissions. However, the efficacy and wider impacts of CDR are poorly understood. Enhanced…
View article: Use of sequential extraction and mercury stable isotope analysis to assess remobilization of sediment-bound legacy mercury
Use of sequential extraction and mercury stable isotope analysis to assess remobilization of sediment-bound legacy mercury Open
Mercury isotope ratios suggest remobilization of recalcitrant legacy mercury from streambed sediment to stream water and biofilm.

Calibrating a long-term meteoric <sup>10</sup> Be delivery rate into eroding western US glacial deposits by comparing meteoric and in situ produced <sup>10</sup> Be depth profiles Open
Meteoric 10Be (10Bemet) concentrations in soil profiles have great potential as a geochronometer and a tracer of Earth surface processes, particularly in fine-grained soils lacking quartz that would preclude the use of in situ produced 10B…

Mercury isotopes identify near-surface marine mercury in deep-sea trench biota Open
Significance Mercury is a globally distributed neurotoxic pollutant that can be biomagnified in marine fish to levels that are harmful for consumption by humans and other animals. The degree to which mercury has infiltrated the oceans yiel…
