Ocean tide is a periodic sea-level oscillation driven primarily by the gravitational forces of the Moon and Sun acting on Earth’s oceans, modulated by Earth’s rotation and the configuration of ocean basins. It manifests as propagating tidal waves with characteristic constituents (e.g., M2, S2, K1) describable by harmonic analysis. Tidal dynamics are governed by the shallow-water equations on a rotating sphere, incorporating Coriolis effects, coastal and seafloor topography, and resonance within semi-enclosed basins. Ocean tides play a fundamental role in coastal hydrodynamics, mixing, sediment transport, and energy dissipation in the Earth–Moon system.
These recent sunny days bring the last chances to access the Rhode Island coastline before chillier weather sets in, though that won't keep Jesse Reiblich away. When he's not in or around the water—as an avid surfer, diver, ...
