Overview: Monitoring, Measuring and Modeling Atmospheric Mercury and Air-Surface Exchange

Mount Etna: Measuring speciated mercury on the flanks of Mount Etna, Sicily during one of the European Tropospheric Mercury Experiment Program (ETMEP, part of the Project, Global

Mercury Observation System (GMOS)). Volcanoes are a natural mercury source and in order to understand the anthropogenic impact on the biogeochemical mercury cycle we also need to

understand the natural emission component [Photo by CNR-IIA].

Tropospheric Mercury Experiment Program saw the aircraft spiraling through the volcanic plume [Photo by CNR-IIA].

Measuring atmospheric mercury in West Atlantic Ocean: Measuring atmospheric mercury on a cruise in the West Atlantic Ocean. The Tekran system to measure mercury with is located on the

side of the ship. During the campaign atmospheric and surface ocean gaseous elemental mercury was measured in order to investigate changes in air-sea exchange fluxes [photo by

industrial point sources and in the free troposphere [Photo by Jaffe Research Group].
