Instruments

Multiple Unit Large Volume Filtration System

Supplied Name: Multi Unit Large Volume Filtration System

Supplied Description:

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

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.

Parameters

Date and time formats are described in python strftime() syntax.
