Data Processing Description

BCO-DMO Processing/Edits
- Generated from MOCNESS data (MN_XX.txt files) contributed by Jessica Forrest-Baldini
- Awk routine "NewHorizon_MN_2_BCODMO.awk" generated to convert MN_XX.txt files to bco-dmo formatted files
- Spaces converted to tabs
- BCO-DMO compatible parameter header generated

Instruments

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.
