The seabed (also known as the seafloor, sea floor, ocean floor, and ocean bottom) is the bottom of the ocean. All floors of the ocean are known as 'seabeds'. The structure of the seabed of the global ocean is governed by plate tectonics. Most of the ocean is very deep, where the seabed is known as the abyssal plain. Seafloor spreading creates ...
The Baltic Sea anomaly sonar image by OceanX. The Baltic Sea anomaly is a feature visible on an indistinct sonar image taken by Peter Lindberg, Dennis Åberg and their Swedish OceanX diving team while treasure hunting on the floor of the northern Baltic Sea at the center of the Gulf of Bothnia in June 2011.
On the bottom of the body was a downward-facing sonar system to monitor the sled's height above the ocean floor. [1] It was capable of working in depths up to 20,000 feet (6,100 m) [ 3 ] and could therefore reach roughly 98% of the sea floor. [ 1 ]
The archaeologists found heaps of stone blocks resting on the sandy bottom at least 14 feet below the water’s surface. Near there, experts also located what is likely a funerary monument dating ...
The old adage that nearly three-quarters of the ocean floor is unreachable is no longer true. Revealing 99% of the ocean floor: WHOI's submersible Alvin reaches new depths Skip to main content
The floor of the ocean off the coast of the Pacific Northwest has sprung a leak called Pythia's Oasis. Here's what that means. Oh Dear, There's A Hole In The Bottom Of The Ocean
A sub-bottom profiler is another sonar system used in geophysical surveys of the sea floor to not only map depth, but also to map beneath the sea floor. [14] Mounted to the hull of a ship, the system releases low-frequency pulses which penetrate the surface of the sea floor and are reflected by sediments in the sub-surface.
A whole new world: Surprising ecosystem thriving under sea floor. The study authors found the tubeworms and other species living in warm, fluid-filled cavities more than 2,500 meters, or 1.5 miles ...
