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 ...

Bathymetry is the underwater equivalent to topography–the study of surface terrain like hills and valleys on land. Just like dry land, the surface of the seafloor is not always flat. The seafloor can ...

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 ...

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 ...

Cold seeps are relatively stable, long-lived places in the ocean where hydrocarbon-rich fluid that is of a similar temperature to surrounding water seeps up from cracks in the seafloor while ...

Del 6 al 19 de abril de 2022, un equipo de investigadores utilizará tecnologías emergentes para explorar los hábitats de aguas profundas en las costas de Puerto Rico que han sido poco explorados, pero ...

As the greatest migration on Earth, the daily vertical movement of zooplankton in the ocean has a massive influence on sea life and the global climate. Every day, billions and billions of animals, ...

Multibeam sonar is a type of active sonar system used to map the seafloor and detect objects in the water column or along the seafloor. The multiple physical sensors of the sonar – called a transducer ...
