Sediment trap

Instrument used in oceanography to measure the quantity of sinking particulate material

Sediment traps are instruments used in oceanography and limnology to measure the quantity of sinking particulate organic material in aquatic systems, usually oceans, lakes, or reservoirs. This flux of material is the product of biological and ecological processes typically within the surface euphotic zone, and is of interest to scientists studying the role of the biological pump in the carbon cycle.
