Description

Methods & Sampling

Dataset acquisition description

Gelatinous zooplankton were sampled using MOCNESS (Multiple Opening-Closing Net and Environmental Sensing System) tows. The nets had opening of 1m2 and 4m2 with mesh sizes of 333µm and 1000µm, respectively. The dataset describes daytime samples only.

Data Processing Description

Dataset Processing Description

Species was identified to the lowest taxonomic level. Length of species was measured onboard using ruler and volume was measured by displacement.

Supplied Description:

Multiple Opening-Closing Net and Environmental Sensing System (MOCNESS). The nets had opening of 1m2 and 4m2 with mesh sizes of 333µm and 1000µm, respectively.

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.
