Ch. 8 & 11

an industrial fishing method where a large net with heavy weights is dragged across the sea floor, scooping up everything

the unwanted fish and over marine creatures caught during commercial fishing for a different species

land along a coastline, extending inland from an estuary that is covered with salt water

warm, nutrient rich, shallow part of the ocean that extends from the high tide mark on land to the edge of a shelflike extension of continental land masses known as the continental shelf

over-nourishment of aquatic ecosystems with plant nutrients because of human activities

an area where most marine life dies or leaves due to less oxygen being dissolved

catching fish in huge nets that drift in the water

upper layer of a body of water through which sunlight can penetrate and support photosynthesis

lake with a large or excess supply of plant nutrients, mostly nitrates and phosphates

physical, chemical, and biological changes that take place after a body of water receives inputs of plant nutrients from natural erosion and runoff from the surrounding land basin

concentration of particular aquatic species suitable for commercial harvesting in a given ocean area or inland body of water

area of ocean needed to sustain the consumption of an average person, a nation, or the world

aquatic systems where water with a dissolved salt concentration of less than 1% by volume accumulates on or flows through the surfaces of terrestrial biomes

the area of shoreline between low and high tides

commercial fishing technique using a long line with baited hooks

lake with low supply of plant nutrients

part of an ocean that lies beyond the continental shelf

harvesting so many fish of a species, especially immature individuals, that not enough breeding stock is left to replenish the species and it becomes unprofitable to harvest them

small, drifting plants, mostly algae and bacteria, found in aquatic ecosystems

precipitation that does not infiltrate the ground or return to the atmosphere by evaporation or transpiration

cloudiness in a volume of water; a measure of water clarity in lakes, streams, and other bodies of water

land area that delivers water, sediment, and dissolved substances via small streams to a major stream

land that is covered all or part of the time with salt water or freshwater, excluding streams, lakes, and the open ocean

marine and freshwater portions of the biosphere
