Atmospheric and dissolved gaseous elemental mercury, photoredox rate constants, and molecular composition of dissolved organic matter in the Arctic Ocean Sangwoo Eom (24124581) Chemical oceanography Earth system sciences Inorganic geochemistry Climate change processes Air pollution processes and air quality measurement Mercury Dissolved gaseous mercury Gaseous elemental mercury FT-ICR-MS Dissolved organic matter Photoreduction rate constant Photooxidation rate constant Arctic Ocean <p dir="ltr">This dataset was used in the manuscript "Air–sea mercury exchange driven by sea-ice loss and mixed-layer dynamics in the Western Arctic Ocean". It includes hourly measurements of gaseous elemental mercury (GEM) in the Arctic atmosphere and dissolved gaseous mercury (DGM) in the Arctic mixed layer at a water depth of 7 m. It also includes experimentally determined rate constants of photoreduction (<i>k</i>_r) and photo-oxidation (<i>k</i>_o) with molecular composition of dissolved organic matter (DOM) analyzed by 15 T FT-ICR-MS. In addition, it provides the relative contributions of DGM sources and sinks in the Arctic Ocean, estimated using a three-media model.</p> 2026-09-28T05:59:41Z Dataset Dataset 10.6084/m9.figshare.33099452.v3 https://figshare.com/articles/dataset/Atmospheric_and_dissolved_gaseous_elemental_mercury_photoredox_rate_constants_and_molecular_composition_of_dissolved_organic_matter_in_the_Arctic_Ocean/33099452 CC BY 4.0
