Instruments

Bongo Net

Supplied Name: Bongo Nets

Supplied Description:

The single bongo deployment used two 2 different net sizes:
335um and 153um.

Instrument Type

Generic Name: Bongo Net

Community Identifier: http://vocab.nerc.ac.uk/collection/L22/current/NETT0009/

Generic Description:

A Bongo Net consists of paired plankton nets, typically with a 60 cm diameter mouth opening and varying mesh sizes, 10 to 1000 micron. The Bongo Frame was designed by the National Marine Fisheries Service for use in the MARMAP program. It consists of two cylindrical collars connected with a yoke so that replicate samples are collected at the same time. Variations in models are designed for either vertical hauls (OI-2500 = NMFS Pairovet-Style, MARMAP Bongo, CalVET) or both oblique and vertical hauls (Aquatic Research). The OI-1200 has an opening and closing mechanism that allows discrete "known-depth" sampling. This model is large enough to filter water at the rate of 47.5 m3/minute when towing at a speed of two knots. More information: Ocean Instruments, Aquatic Research, Sea-Gear
