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
Model of a sediment trap: It mainly consists of a huge funnel, a ring of Glass floats (3 are visible) and a revolving wheel with sample bottles.
Sediment trap deployment in Thermaikos Gulf, Greece, 2000. The sediment trap has H/D 5.5, internal diameter 127 mm, and a net at the top. The sediment trap had been cast at 25-30 m depth and 3 m above seabed. The anchor (chain) of the mooring can also be seen.

The carbon cycle is a part of the biogeochemical cycle where carbon is exchanged among the biosphere, pedosphere, geosphere, hydrosphere, and atmosphere of Earth. Other major biogeochemical cycles inc
Carbon cycle schematic showing the movement of carbon between land, atmosphere, and oceans in billions of tons (gigatons) per year. Yellow numbers are natural fluxes, red are human contributions, and white are stored carbon. The effects of the slow (or deep) carbon cycle, such as volcanic and tectonic activity are not included.

Where terrestrial carbon goes when water flows
How carbon moves from inland waters to the ocean Carbon dioxide exchange, photosynthetic production and respiration of terrestrial vegetation, rock weathering, and sedimentation occur in terrestrial ecosystems. Carbon transports to the ocean through the land-river-estuary continuum in the form of organic carbon and inorganic carbon. Carbon exchange at the air-water interface, transportation, transformation and sedimentation occur in oceanic ecosystems.
