The deep ocean is filled with with strange life-forms. But what’s down there? Ninety-five percent of the ocean remains unexplored, most of which is considered the deep ocean. Exploring the deep ocean is challenging because of the harsh conditions, but marine scientists are on a mission to document new species in this unusual place.

Scientists believe that 80 percent of the volcanic eruptions on Earth take place in the ocean. Most of these volcanoes are thousands of feet deep and difficult to find. In May of 2009, scientists captured the deepest ocean eruption ever found. Nearly 4000 feet below the surface of the Pacific Ocean, the West Mata volcano was discovered.
Rented by the BP Oil Company to drill an oil well in the Gulf of Mexico, the Deepwater Horizon drilling rig explodes on April 20, 2010. It sinks into the ocean and causes a gigantic oil spill. At issue is negligence in the maintenance and in the tests carried out. On September 19, after months of unsuccessful attempts, the spill is finally declared sealed. However, this incident has generated the largest marine oil disaster in history. Part of the "Butterfly Effect" series.
In this episode, a team of scientists, ranging from biologists to volcanologists, embark on an international expedition to the Mariana Arc on the Pacific Rim of Fire. Each day they make new discoveries about outlandish deep-sea dwellers and dramatic underwater volcanoes. But even as the scientists catalog these new findings, industrial fisheries are delving further into deep waters in an attempt to replace diminishing fish stocks. Part of the "One Ocean" series.
This creature was found 6,900 feet deep in the ocean. It’s a deepsea lizardfish, also called a Bathysaurus ferox. It is the world’s deepest living superpredator and will eat anything it meets. Part of the "Creatures of the Deep" series.
This creature was found 2,300 feet deep in the ocean. It’s a sea spider, and ones living at this depth can grow quite large, spanning almost 3 feet wide. Their 8 long legs help carry vital organs like their digestive tract. They also have 3 to 4 extra limbs, which they use for cleaning, courtship, and carrying their young. With over 1,300 different species, they are found in every ocean throughout the world. Part of the "Creatures of the Deep" Series.
This creature was found 4,200 feet deep in the ocean. It’s called a chimaera, and this fish has no bones in its body. Its skeleton is made of cartilage. The dots on its face are sensory organs that detect electrical fields in the water, which help the chimaera find its prey. Living in deep water, the chimaera is accustomed to lurking in the dark. Part of the "Creatures of the Deep" series.
This creature was found 1,600 feet deep in the ocean. The anglerfish is distinguished by the rod protruding from its head that it uses to attract prey. With flexible bones, and a stomach that can be expanded, it can swallow fish that are twice its size. The pectoral and pelvic fins can perform as feet, allowing this fish to walk along the bottom of the sea. This strange-looking creature is an example of the bizarre life-forms living deep below the surface. Part of the "Creatures of the Deep" series.
This creature was found 1,800 feet deep in the ocean. It’s called a basket star. This extraordinary invertebrate has a mass of twisting and turning arms that can measure a meter long. Each branch has tiny sharp hooks allowing the creature to capture prey, and it feasts mainly on zooplankton. Basket stars are able to grow their limbs back if they are broken or chopped off by predators. Part of the "Creatures of the Deep" series.
More than 70 underwater canyons exist off the northeastern coast of the United States, and some are more than three miles deep. In this video, journey to some of the deep canyons and discover new species of sea coral through the eye of a remotely operated vehicle (ROV).
The rim of the Pacific Basin is one of the most geologically active places on Earth, and scientists have nicknamed the area "The Ring of Fire." The movement of tectonic plates has created a nearly continuous series of oceanic trenches and chains of volcanoes stretching for twenty-five thousand miles. Part of the "Deep Sea Dive" series.
The seafloor has a diverse landscape, which includes underwater lakes and rivers. How is that possible? Well, these lakes and rivers form when seawater seeps up through thick layers of salt, which are present beneath the seafloor. As the water seeps up, it dissolves the salt layer, causing it to collapse and form depressions. The dissolved salt makes the water denser, and because it is denser than the water around it, it will settle into the depressions, forming a river or lake. Part of the "Deep Sea Dive" series.
Sharks have been swimming the ocean for 400 million years. But today, many species of sharks are in deep decline due to overfishing and shark finning. A healthy ocean needs sharks. Thankfully awareness of their importance is growing. Part of the "Endangered Ocean" series.
It's cold; it's dark. The pressure is immense. A pilot and scientist from the Monterey Bay Aquarium Research Institute navigate a remotely operated deep-sea vehicle through underwater canyons, filming the ocean floor and collecting samples.
Hydrothermal vents were originally discovered near the Galapagos Rift in 1977. They form from hot springs produced by underwater volcanoes or tectonic activity. Scientists have found an abundance and assortment of life that has adapted to the harsh, dark conditions surrounding these seafloor vents. Part of the "Deep Sea Dive" series.
In 1977, scientists discovered a diverse community of organisms inhabiting the deep-sea hydrothermal vents of the Pacific Ocean. The sources of energy in these ecosystems are hydrogen sulfide and other inorganic chemicals that are abundant in the water that rises from the vents. Scientists discovered that some animals living near hydrothermal vents, such as the giant tube worm, have a symbiotic relationship with species of bacteria, which allows these animals to survive deep in the ocean. Part of the "I Contain Multitudes" series.
The mesophotic zone exists between brightly lit shallow waters and the deepest, darkest depths of the ocean. It is the furthest that sunlight can penetrate the ocean. Only recently, with advancements in diving techniques and new technology, have scientists been able to study it in-depth.
In September 2005, members of an ocean exploration captured video footage of the white deep-sea octopod, Grimpoteuthis bathynectes. They nicknamed the octopod “Dumbo” because of its large ear-like fins. These fins and webbed arms help it swim through the water.
NOAA's environmental satellites provide data from space to monitor Earth to analyze coastal waters, relay life-saving emergency beacons, and predict and track tropical storms and hurricanes. NOAA operates three types of satellite systems for the United States: polar-orbiting satellites, geostationary satellites, and deep space satellites. Polar-orbiting satellites circle Earth and provide global information from 540 miles above Earth. Geostationary satellites constantly monitor the Western Hemisphere from around 22,240 miles above Earth. The deep space satellites orbit one million miles from Earth, providing space weather alerts and forecasts while also monitoring the amounts of solar energy absorbed by Earth every day.
Bioluminescence is a chemical process that allows living things to produce light. On land, fireflies are one of the most visible users of bioluminescence. In the ocean, bioluminescent creatures can be found from the surface all the way down to the deep sea floor. Scientists are still trying to figure out why and how animals adapted this feature.
