Large deep sea communities of marine life have been discovered around black and white smokers — vents emitting chemicals toxic to humans and most vertebrates.
Remotely operated underwater vehicle (ROV) built by the Japan Agency for Marine-Earth Science and Technology (JAMSTEC) for exploration of the deep sea.
In August 2000, Kaikō discovered hydrothermal vents and their associated deep sea communities at a depth of 2,450 meters near the Central Indian Ridge.
Extinct species of mackerel shark that lived approximately 23 to 3.6 million years ago (Mya), from the Early Miocene to the Pliocene epochs.
The claims that megalodon could remain elusive in the depths, similar to the megamouth shark which was discovered in 1976, are unlikely as the shark lived in warm coastal waters and probably could not survive in the cold and nutrient-poor deep sea environment.
Underwater plain on the deep ocean floor, usually found at depths between 3000 m and 6000 m. Lying generally between the foot of a continental rise and a mid-ocean ridge, abyssal plains cover more than 50% of the Earth's surface.
Limited knowledge of the taxonomy, biogeography and natural history of deep sea communities prevents accurate assessment of the risk of species extinctions from large-scale mining.
Growing subfield of experimental seabed mining that involves the retrieval of minerals and deposits from the ocean floor found at depths of 200 meters or greater.
Many opponents to deep sea mining efforts point to the threats of grave and irreversible damage it could cause to fragile deep sea ecosystems.
Provided as an overview of and topical guide to fishing:
Deep sea communities – Deep sea communities currently remain largely unexplored, due to the technological and logististical challenges and expense involved in visiting these remote biomes.
Extinct genus of toothed whale in the sperm whale family with one species, B. shigensis.
The formation also had fossil bivalves which indicate the presence of deep-sea hydrothermal vents, and there is also evidence of prehistoric cold vents in the area, which today host chemosynthetic specialist species; the formation was likely 1000 – deep in the Miocene.
Concept in ecology, in which an organism obtains protection from predation by hiding in an area where it is inaccessible or cannot easily be found.
The largest such migration by biomass is the oceans' diel vertical migration, in which vast quantities of organisms hide in the lightless depths of the open ocean, arising after dark to consume phytoplankton.
Environmental effects of mining can occur at local, regional, and global scales through direct and indirect mining practices.
Deep sea mining for manganese nodules and other resources have led to concerns from marine scientists and environmental groups over the impact on fragile deep sea ecosystems.
Field project of the Census of Marine Life programme .
The main aim of ChEss is to determine the biogeography of deep-water chemosynthetic ecosystems at a global scale and to understand the processes driving these ecosystems.
