Contaminated Coasts: Submarine Groundwater Discharge

Contaminated Coasts: Submarine Groundwater Discharge

Pollution can reach the sea from underground. Marine geochemist Dr. Tristan McKenzie explains how submarine groundwater discharge carries nutrients, heavy metals, and pharmaceuticals into coastal waters. Drawing on research in Hawaii and Sweden, the episode explores geochemical tracers, groundwater pollution, and the hidden pathways connecting activity on land with ocean contamination and coastal ecosystem health.
