Marine sediment, or ocean sediment, or seafloor sediment, are deposits of insoluble particles that have accumulated on the seafloor.

Deep-sea sediments can reveal much about the last 200 million years of Earth history, including seafloor spreading, the history of ocean life, the behaviour of Earth’s magnetic field, and the …

Marine sediment, any deposit of insoluble material, primarily rock and soil particles, transported from land areas to the ocean by wind, ice, and rivers, as well as the remains of marine …

Deep-sea sediments may be interpreted as the product of three main processes: gravity-driven downslope resedimentation, alongslope bottom current activity, and slow pelagic settling …

There are four types of sediment: cosmogenous (from outer space), volcanogenous (ash from volcanic eruptions), terrigenous (continents erosion and river runoff), and biogenous …

Marine sediments represent the most pervasive habitat on Earth, yet encompass a wide diversity of specialized environments from the intertidal zone to the deepest ocean trenches.
