Physical Oceanography: Water Currents and Sediment Transport

Physical Oceanography is the study of the physics of the oceans, especially the complex water movements and the forces caused by tides, winds, and temperature differences that generate those movements. The physical oceanography in Long Island Sound is crucial both in understanding the distribution of sedimentary environments and in predicting the long-term fate of wastes and contaminants that have been introduced there. Water current patterns and sediment transport patterns create the sea-floor environment that we observe.
