Instruments

Intelligent Operative Net Sampling System

Supplied Description:

Instrument Type

Generic Name: Intelligent Operative Net Sampling System

Acronym: IONESS

Community Identifier: http://vocab.nerc.ac.uk/collection/L05/current/22/

Generic Description:

The Intelligent Operative Net Sampling System (IONESS) is a sampling net system similar to a MOCNESS that is towed through the water column and can be controlled to open and close over specified depth intervals.

MOCNESS

Supplied Description:

Instrument Type

Generic Name: MOCNESS

Community Identifier: http://vocab.nerc.ac.uk/collection/L22/current/NETT0097/

Generic Description:

The Multiple Opening/Closing Net and Environmental Sensing System or MOCNESS is a family of net systems based on the Tucker Trawl principle. There are currently 8 different sizes of MOCNESS in existence which are designed for capture of different size ranges of zooplankton and micro-nekton Each system is designated according to the size of the net mouth opening and in two cases, the number of nets it carries. The original MOCNESS (Wiebe et al, 1976) was a redesigned and improved version of a system described by Frost and McCrone (1974).(from MOCNESS manual) This designation is used when the specific type of MOCNESS (number and size of nets) was not specified by the contributing investigator.
