Hydrothermal Circulation and Seawater Chemistry

Hydrothermal Circulation and Seawater Chemistry, 1st Edition, investigates the dynamic relationship between fluid flow through ocean crust and seawater composition. Designed for researchers, students, and professionals, this 2026 volume examines how both on-axis and off-axis hydrothermal systems influence marine chemistry and broader planetary systems.

The text structures its analysis around fluid-rock reactions occurring over a wide thermal spectrum. Interactions between seawater and underlying ocean crust happen at temperatures ranging from approximately 2°C at the seafloor to exceeding 500°C deep within the crust. Hydrothermal reactions alter the chemical composition of seawater, while existing seawater chemistry directly influences hydrothermal exchange.

A primary focus of the text highlights how low-temperature off-axis hydrothermal systems transport large fluxes of elements across ocean basins. By detailing these fluid interactions, the text supports advanced study into the broader role of oceanic hydrothermal circulation within planetary-scale cycles on Earth and beyond.
