 Application (What is Sediment Trap?)
Sediment Trap automatically collects time-series sinking particle sample.
Sinking particles on land are precipitation (rain & snow), dust and sea-salts.
Sinking particles in water are carcasses of plankton, fecal pellets and lithogenic matter
(something from land; sand, mud, aeolian dust).

Sediment trap are used for
