Ocean Ecosystems: Everglades to Sea Vents

Everglades Ecology: A look at the everglade ecosystem and the balance between prey and predator. Fish feed on algea, alligators feed on fish, and birds feed on snails and fish. 
Large Scale Fishing: Bottom trawling, commercial fishing has huge environmental impacts, devastating the life on the bottom of the ocean floor. In addition to torn up seabeds, unintentional animals get caught in the massive nets. Sea turtles, dolphins and others are at risk, although trap-doors in improved nets try to mitigate the effects.
The complex ocean food web can easily be disrupted at multiple points by pollution like an oil spill.

Neptune Ocean Sensor Network: In the Pacific Northwest off Vancouver island 500 miles of fiber optic cable connect 6 different underwater research stations. Varying from 70 feet deep on the continental shelf to over 7000 ft deep in the great abyss, each station, or node has numerous instruments to track water chemistry, gelogic data and animals and more, all in real time. 
Sea Vent Ecology: 1.5 miles beneath the ocean's surface on the seafloor exists a strange and fascinating world that thrives in the absence of sunlight. Hydrothermal vents support a rich ecosystem that includes fish, shrimp, tubeworms, mussels, crabs, and clams. In the absence of sunlight specially adapted bacteria and similar organisms, called archaea, are able to convert the chemicals into useable bio-energy.
