Hydrothermal Circulation and Seawater Chemistry

Exploring how oceanic hydrothermal systems influence seawater chemistry The chemical exchange between seawater and the underlying ocean crust occurs at temperatures ranging from about 2°C on the seafloor to more than 500°C deep in the crust. These hydrothermal reactions strongly influence the chemical composition of seawater and, in turn, seawater chemistry impacts hydrothermal exchange; these feedbacks play a crucial role in the Earth system. Hydrothermal Circulation and Seawater Chemistry: Links and Feedbacks explores on- and off-axis hydrothermal systems and their effects on ocean chemistry and the Earth system. Volume highlights include: Hydrothermal fluxes dependent on boundary conditions such as climate and sedimentation historyLow-temperature, off-axis systems that have large fluxes of elementsObservational and experimental perspectives of on-axis hydrothermal processesMethods for tracking hydrothermal and oceanic processes using sediments or isotope proxiesThe role of oceanic hydrothermal systems in planetary-scale cycles on Earth and beyondThe American Geophysical Union promotes discovery in Earth and space science for the benefit of humanity. Its publications disseminate scientific knowledge and provide resources for researchers, students, and professionals.
