Deep-sea Community
A deep-sea community is any community (ecology), community of organisms associated by a shared habitat in the deep sea. Deep sea communities remain largely unexplored, due to the technological and logistical challenges and expense involved in visiting this remote biome. Because of the unique challenges (particularly the high Atmospheric pressure, barometric pressure, extremes of temperature, and aphotic zone, absence of light), it was long believed that little life existed in this hostile environment. Since the 19th century however, research has demonstrated that significant biodiversity exists in the deep sea. The three main sources of energy and nutrients for deep sea communities are marine snow, whale falls, and chemosynthesis at hydrothermal vents and cold seeps. History Prior to the 19th century scientists assumed life was sparse in the deep ocean. In the 1870s Charles Wyville Thomson, Sir Charles Wyville Thomson and colleagues aboard the Challenger expedition discovered man ...
