The Cook Islands is endowed with seabed resources within its vast ocean territory. Scattered across the seafloor within the island nation’s territorial waters are found dense polymetallic nodules of ...
The deepest confirmed fish sighting is of a snailfish filmed at a depth of 8,336 meters (27,000 feet) below the ocean surface. Other fish may live at similar depths, but it’s likely that no fish lives ...

The stories that emerge from material culture left behind by our predecessors span time and geography. Dugout canoes built from single trees and excavated out of river banks tell the stories of ...
Understanding of Methane Seep Formation and Prevalence on U.S. Atlantic Margin Advanced by New Study
A major new study on the distribution and origin of methane seeps on the U.S. Atlantic margin — the seafloor between the coast and the deep ocean — expands the inventory of methane seeps (also called ...
Covering 6.4 million acres, an area larger than Vermont, an underwater seascape of cold-water coral mounds offshore the southeast United States coast has been deemed the largest deep-sea coral reef ...
Amid a smattering of white sponges, this smooth, gold, dome-shaped specimen, a little over 10 centimeters (4 inches) in diameter, was tightly adhered to a rock. A small hole or tear near its base ...
Ocean exploration is vital for mapping and characterizing geologic features and biologic communities in the ocean, some of which have not been previously described. However, the impacts of ocean ...
A sub-bottom profiler is a type of sonar system – a geophysical survey tool that uses sound to map beneath the seafloor. Low-frequency pulses of sound are aimed toward the seafloor, where some pulses ...
Oxygen minimum zones are persistent layers in the water column that have low oxygen concentration due to biological, chemical, and physical processes. As oceans warm, oxygen minimum zones increase in ...
The deep scattering layer (or DSL) is a region in the water column where there is a high density of marine organisms that reflect sound. During World War II, technicians using the then newly invented ...
During Dive 04 of the second Voyage to the Ridge 2022 expedition, we observed several sublinear sets of holes in the sediment on the seafloor at a depth of approximately 2,540 meters (1.6 miles).
