Seabed - Wikipedia
网页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 Mapping - NOAA Ocean Exploration
网页2022年7月20日 · Only slightly more than 23% of the seafloor has been mapped in great detail, and even less has been explored with underwater cameras or submersibles. Mapping the seafloor is the first step in exploring the unknown depths of our global ocean.

网页2022年4月27日 · The seafloor has distinct features and characteristics that help us better understand Earth’s current and past conditions, potential resources, and natural hazards. However, less than 10% of the seafloor has been mapped globally.
Seafloor Spreading - National Geographic Society
网页2023年11月29日 · Seafloor spreading is a geologic process in which tectonic plates —large slabs of Earth's lithosphere —split apart from each other. Seafloor spreading and other tectonic activity processes are the result of mantle convection. Mantle convection is the slow, churning motion of Earth’s mantle.

网页The ocean floor covers more than 70 percent of the planet’s surface. Like dry land, the ocean floor has various features including flat plains, sharp mountains, and rugged canyons (Fig. 7.1). However, the lowest point in the world ocean is …
Why Map the Seafloor? To Understand What’s There
网页Enter seafloor mapping. Seafloor mapping is the first step in exploring our ocean. Once scientists or resource managers have identified an area they would like to know more about, ships equipped with technology such as multibeam sonar can collect data used to generate high-resolution bathymetric maps of that part of the seafloor.
8.3: The Seafloor - Geosciences LibreTexts
网页The ocean surface is vast and hides an entire world underneath it. The ocean floor is sometimes called the final frontier of the modern era. Though people have traveled on the ocean for millennia, people have explored only a tiny fraction of the ocean floor. We know very little about the vast expanse of our oceans.
