Description

Tow Photos from Polarstern Cruise ANT-XXIV-1
Oct - Nov, 2007

Photographs were taken in the "Cold Container", alias the cold wet lab, of the Polarstern of the contents of each net in a tray before any animals were picked out. Nancy Copley used her own equipment. See parameter list for settings.

Instruments

MOCNESS10

Supplied Description:

Mocness 10 with .333micron mesh in nets 1-8 and 3mm mesh in net 0.

Instrument Type

Generic Name: MOCNESS10

Acronym: MOC10

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

Generic Description:

The Multiple Opening/Closing Net and Environmental Sensing System (MOCNESS) is based on the Tucker Trawl principle (Tucker, 1951). The MOCNESS-10 (with 10 m^2 nets) carries 6 nets of 3.0-mm circular mesh which are opened and closed sequentially by commands through conducting cable from the surface (Wiebe et al., 1976). In this system, "the underwater unit sends a data frame, comprising temperature, depth, conductivity, net-frame angle, flow count, time, number of open net, and net opening/closing, to the deck unit in a compressed hexadecimal format every 2 seconds and from the deck unit to a microcomputer every 4 seconds" (Wiebe et al., 1985).
