Geophysics & Environmental Physics

Hydrologic Cycle

The continuous global movement and transformation of water through Earth's atmosphere, land surface, oceans, and subsurface aquifers.

Water Balance: P = E + R + ΔS (Precipitation = Evaporation + Runoff + Storage Change) Global Water Flux (km³/year) Geophysics & Environmental Physics

Hydrothermal Vents

Fissures on the ocean floor near volcanically active mid-ocean ridges that vent geothermally heated, mineral-rich seawater into the ocean.

Geothermally Heated Seawater T ~ 350–400 °C °C (Vent Fluid Temperature)
