Answer:
Upwelling, the rising of water from deeper layers of the ocean, is a wind-induced movement that brings cold and nutrient rich water to the surface.
Explanation:
Marine resurgence is an oceanographic phenomenon that occurs when subsurface waters rise. These waters consist of a large amount of nutrients and have a lower temperature than surface waters, becoming colder. This phenomenon generally occurs in areas where primary production is high, or when there is strong fishing activity in the region.
The city of Los Angeles released 96 million "shade balls" into the Los Angeles Reservoir. These will serve to shield the water from the sun's heat in order to reduce evaporation and prevent algal and bacterial growth so no toxic substances are produced in the water. The balls reduce evaporation by 85%-90% so will save a lot of water yearly.
