Document Summary
Environ 201- chapter 16: marine and coastal systems and resources. Continental shelves: the gently sloping underwater edge of a continent, varying in width from 100 m to 1300 km, with an average slope of 1. 9 m/km. Current: the flow of a liquid or gase in a certain direction. Upwelling: in the ocean, the flow of cold, deep water toward the surface; occurs in areas where surface currents diverge. Downwelling: in the ocean, the flow of warm surface water toward the ocean floor; occurs where surface currents converge. Thermohaline circulation: a worldwide system of ocean currents in which warmer, fresher water moves along the surface and colder, saltier water (which is denser) moves deep beneath the surface. El ni o-southern oscillation (enso): a systematic shift in atmospheric pressure, sea surface temperature, and ocean circulation in the tropical pacific ocean and gives rise to the el ni o and la ni a conditions.
