Global Oceans Atlantic, Pacific, Indian, Arctic, and Southern Technology (used to study oceans) Sonar- sound navigation and ranging, a system that uses acoustic signals and returned echoes to determine the location of objects or to communicate Submersibles- Human piloted or self piloted, vessels sent underwater that can do a various of jobs like taking photographs, collecting mineral samples. Drilling Ships- Ships used to obtain core samples, that are used for testing Continental vs. Oceanic crust The boundary between the oceanic, and continental crust is located at the base of the continental basin. Ocean Basin Features Trenches Long, narrow, and steep depression that forms on the ocean floor as a result of subduction of a tectonic plate Abyssal Plains A large, flat, almost level area of the deep-ocean basin Mid-Ocean Basins Form underwater mountain ranges that run along the floors of all oceans. Seamounts Submerged volcanic mountains that are taller than 1 km Ocean Sediments Inorganic Sediments- Sediments brought from the land by rivers that don’t originate from living organisms Biogenic Sediments- sediments that originate from living organisms Chemical Sediments- Minerals, or sediments that form from the crystallization of Nodules. How Sediments Settle… Finer, and smaller particles will take along time to settle opposed to the bigger and heavier particles that settle faster. Finer and smaller particles settle on the deep ocean basins, while the heavier, and coarser particles settle by, or on the shore.
