Pelagic sediment refers to the fine particles that accumulate on the ocean floor, primarily composed of organic matter, minerals, and tiny marine organisms. These sediments are transported by ocean currents and can originate from various sources, including the remains of plankton, dust from land, and volcanic ash. The composition of pelagic sediment varies depending on the location and depth of the ocean. In deeper areas, sediments tend to be richer in organic material, while shallower regions may contain more mineral content. Understanding pelagic sediment is essential for studying marine ecosystems and the geological history of the Earth.
