|Cold Seeps (Cold Vents)|
The effluent from the hydrothermal vents, black smokers, is chemically rich and hot enough to melt lead. They are found in volcanically active locations within tectonic plate zones.
Cold Seeps (Cold Vents) are sites where oil and methane mixed with water 'seep' from fissures and become diffused with sediments. They spread over a very wide area and develop a unique topology.
The reaction of hydrocarbons and seawater create carbonate rock formations and reefs. The chemically rich effluent often forms a brine pool on the ocean floor. The word 'Cold' does not mean the effluent is colder than the surrounding sea water. Mostly it is often a bit higher in temperature. Cold seeps often support a diverse Biome that serves many indigenous species. Cold seeps are categorized by depth. They arise over fissures located on the seafloor due to tectonic activity.
