Riftia tubeworm ( Riftia pachyptila ) colonies grow where hot, mineral-laden water flows out of the seafloor in undersea hot springs—such as the Guymas Basin of the Gulf of California at 2,000 meters (6562 feet), where MBARI took...

It may be the last place you’d expect to find corals—up to 6,000 m (20,000 ft) below the ocean’s surface, where the water is icy cold and the light dim or absent. Yet believe it or not, lush coral...
Orange shaded areas are major drainage basins of Belize, Guatemala, and Honduras that contribute sediment to the Caribbean. Wind and current patterns are represented by red and black arrows,...
Travel to a world of perpetual night--the deep ocean hydrothermal vents near the Galapagos Rift where life thrives around superheated water spewing from deep inside the Earth. Discovered only in 1977...
Kilauea Volcano, Kalapana, Hawaii, USA “In the upper left of this image I can visualize the profile of Pele, the fire goddess of Hawaiian folklore, as if she is whispering to the sea.” -- Nature's...
Imagine: You’re in a small submersible, and you gently settle on the soft muddy bottom at a depth of 12,000 feet. It’s absolutely dark. What will you see when the exterior lights are turned on? Will...
Scientists don’t often get the opportunity to travel through time. But nestled among the beautiful coral reefs of Papua New Guinea (PNG) is a place that provides a glimpse today of what could be the...
A giant tortoise subspecies ( Geochelone nigra vicina ) lives on Isabela Island in the Galapagos. Cerro Azul, estimated to be about 350,000 years old, is one of six volcanoes on the island.
A volcanic eruption of superheated magma (some 2,200 degrees Fahrenheit) from the West Mata Volcano produces a bright flash of hot magma that is blown up into the water before settling back to the...
Recent scientific discoveries have revealed an underwater community of marine animals and other organisms that thrive in the dark depths of the ocean near hydrothermal vents and undersea volcanoes...
Census researchers manipulate the robotic arm of the remotely operated vehicle (ROV) Quest to study shrimp and other deep sea life forms. They discovered the creatures at a hydrothermal vent 3...
Riftia tubeworm ( Riftia pachyptila ) colonies grow where hot, mineral-laden water flows out of the seafloor in undersea hot springs—such as the Guymas Basin of the Gulf of California at 2,000 meters...
Since 1902, more than 40 centimeters of mangrove peat could have accumulated at the Belize site, enough to entrap and bury small pieces of pumice. But Juan’s vexing questions persisted: Why hadn’t...
But what path, precisely, did this pumice take to reach Belize from the Guatemalan Highlands? Maps of drainage networks that reach the Gulf of Honduras and currents in the western Caribbean Sea are...
Superheated magma, about 2,200 degrees Fahrenheit, glows orange as it slowly leaks from cracks along the six-mile long active rift zone of the West Mata Volcano in the Pacific Ocean near Fiji. The...
Did you know that 80 percent of the volcanic eruptions on Earth take place underwater? These underwater eruptions occur regularly, forming new landmasses and providing a living environment for deep-...
As a geological oceanographer at the Smithsonian National Museum of Natural History, Dr. Maggie Toscano has made a career of documenting how coastal systems have changed over thousands of years in...
NOAA’s New Millennium Observatory (NeMO) was set up to study geologic, chemical, and biologic interactions along the mid-ocean ridge system. Learn more about NeMO and watch a video about underwater...
The yeti crab ( Kiwa hirsuta ), an unusual, hairy crab with no eyes, was discovered in 2005 on a hydrothermal vent near Easter Island. It represents not only a new species but also a new genus— Kiwa...
