Instruments

Sediment Trap - Particle Interceptor

Supplied Name: Particle Interceptor Trap

Supplied Description:

MLML Particle Interceptor Sediment Trap (MLML = Moss Landing Marine Laboratory)

Instrument Type

Generic Name: Sediment Trap - Particle Interceptor

Acronym: Sed Trap - Part Int

Community Identifier: http://vocab.nerc.ac.uk/collection/L05/current/33/

Generic Description:

A Particle Interceptor Trap is a prototype sediment trap designed in the mid 1990s to segregate 'swimmers' from sinking particulate material sampled from the water column. The prototype trap used 'segregation plates' to deflect and segregate 'swimmers' while a series of funnels collected sinking particles in a chamber (see Dennis A. Hansell and Jan A. Newton. September 1994. Design and Evaluation of a "Swimmer"-Segregating Particle Interceptor Trap, Limnology and Oceanography, Vol. 39, No. 6, pp. 1487-1495).
