Instruments

Multiple Unit Large Volume Filtration System

Supplied Name: Multi Unit Large Volume Filtration System

Supplied Description:

Multiple Unit Large Volume in situ Filtration System(MULVFS) used to collect water.

Instrument Type

Generic Name: Multiple Unit Large Volume Filtration System

Acronym: MULVFS

Community Identifier: http://vocab.nerc.ac.uk/collection/L05/current/32/

Generic Description:

The Multiple Unit Large Volume Filtration System (MULVFS) was first described in Bishop et al., 1985 (doi: 10.1021/ba-1985-0209.ch009). The MULVFS consists of multiple (commonly 12) specialized particulate matter pumps, mounted in a frame and tethered to the ship by a cable (Bishop et al., 1985; Bishop and Wood, 2008). The MULVFS filters particulates from large volumes of seawater, although the exact protocols followed will vary for each project.
