The kelp then sinks to the ocean floor and store the carbon where is it unlikely to be disturbed by human activity. [71] Researchers from the University of Western Australia estimated kelp forest around Australia sequestered 1.3-2.8 teragrams of carbon per year which is 27–34% of the total annual blue carbon sequestered in the Australian ...
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 ...
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 ...
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.
An abyssal plain is an underwater plain on the deep ocean floor, usually found at depths between 3,000 meters (9,800 ft) and 6,000 meters (20,000 ft).Lying generally between the foot of a continental rise and a mid-ocean ridge, abyssal plains are among the flattest, smoothest and least explored regions on Earth.

The grave slabs, which were located about 22 feet underwater, were hauled to the surface by maritime archaeologists during a two-hour recovery operation on June 4, university officials said.
A marine coastal ecosystem is a marine ecosystem which occurs where the land meets the ocean. Worldwide there is about 620,000 kilometres (390,000 mi) of coastline. Coastal habitats extend to the margins of the continental shelves, occupying about 7 percent of the ocean surface area.
Divers discovered two well-preserved onion glass bottles from a shipwreck in the Atlantic Ocean off the coast of Indian River County in Florida in 2021 and 2022. While the exact ship has yet to be ...
