MSCI 210 Lecture Notes - Lecture 18: Marine Energy, Marine Pollution, Noodle
Document Summary
Classification of marine resources: physical resources. Result from the deposition, precipitation, or accumulation of useful substances in the ocean or seabed: biological resources. Living animals and pets collected for human use: marine energy resources. Result from the extraction of energy directly from the heat or motion of ocean water: nonextractive resources. Uses of the ocean in place, transportation, waste disposal, recreation. Naturally replaced by a physical process: nonrenewable. Oil, gas, ans solid mineral deposits are present in the ocean in fixed amounts and cannot be replenished over time periods as short as a human lifespan. Physical resources: petroleum and natural gas. 34% of crude oil and 30% of natural gas: marine sand and gravel for construction, salts from evaporation ponds, potable water from desalination, petroleum and natural gas are most valuable ocean resources. High and steady winds near the ocean: waves. Pool noodle things that make energy: currents, tides.
