Description

SEEDS 2001 Mesozooplankton
Abundance of zooplankters for most stations IN and OUT (all except day 13).
Results are given as individuals per m2 by species and copepodite stage.

Methods & Sampling

Dataset acquisition description

Samples were collected with VMPS (Vertical Multi-layer Plankton Sampler)
with a 50x50cm mouth opening and 100um mesh
Samples were collected between 0-20, 20-50, 50-100 and 100-200m.

Samples were immediately fixed with 10% buffered formalin.
Listed zooplankters were identified counted and sorted out from the sample.
Species and copepodite stage are given

Notes from CSV file generated by Doug Mackie:
Species and copepodite stage are given
Wet weight of the sorted samples were measured for copepods and non-copepod organisms

Detailed descriptions of the method are presented by Tsuda et al. (2005) in the special volume of Progress in Oceanography

Instruments

Vertical Multi-layer Plankton Sampler

Supplied Description:

Instrument Type

Generic Name: Vertical Multi-layer Plankton Sampler

Acronym: VMPS

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

Generic Description:

The Vertical Multiple Plankton Sampler (VMPS), a variation of the multiple plankton sampler (MPS), is a specially designed opening-closing, multi-layer net system used for collecting zooplankton (Terazaki and Tomatsu, 1997). The mesh size and mouth opening can vary depending on research focus. The VMPS is towed through depth ranges with nets closed at known intervals to yield estimations of standing stock, vertical distribution and diel vertical migration.

The VMPS as described by Wiebe and Benfield (2003) is named the Ocean Research Institute Vertical Multiple Plankton Sampler (ORI-VMPS) with specifications: 100 cm x 100 cm rectangular mouth opening multiple net system that can be equipped with 4 to 10 nets, 510 cm long with 0.33 mm nylon mesh. Nets are opened/closed by surface commands down
transmitted via conduction cable to an underwater
unit (see Plate 31 C (Wiebe and Benfield, 2003)).
