Stable Mercury Isotopic Analyses in Natural Matrices via Rapid Pre-Concentration Method Data Release
This data relates to the development of a modified pre-concentration method for mercury (Hg) stable isotope measurements that uses chemical Hg reduction and gold trap amalgamation followed by...

Fish collected for taxonomic and systematic purposes are often preserved and then archived in museum collections. Preserved fish are commonly first fixed in a formalin solution and then...
-
Mercury isotope measurements were made across nine sediments cores from remote North American lakes to examine changes in the Hg isotope profiles. The lakes spanned regions of Alaska, Minnesota,...

Laboratory experiments were performed between 2019 and 2020 to examine how dissolved organic matter (DOM) and phytoplankton (Raphidocelis subcapitata) cells alter mercury (Hg) uptake and isotope...
-
Atmospheric mercury (Hg) deposition, which has been declining in North America since 1985, is the preeminent delivery pathway to the Great Lakes, making them sentinels for tracking shifts in...
-
Mercury (Hg) concentrations and isotopic compositions were collected in sediments, soils, and suspended particulate matter from Gruber's Grove Bay (GGB) and upstream reference sites to inform...
-
This dataset describes mercury (Hg) stable isotope values in fish dorsal muscle from different freshwater environments across the globe. Fish were collected at numerous field sites in North...
-
This dataset describes mercury (Hg) and methylmercury (MeHg) concentration data and Hg and MeHg stable isotope values in plankton, waters, and sediments that were collected from two inland...
