Indian Ocean Standard Net Oceanographic non-opening/non-closing net for vertical operations
The Indian Ocean Standard Net is the standard nonopening/ non-closing plankton net for quantitative sampling of larger volumes of water during vertical tows. A 113 cm diameter stainless steel ring with a 4.7 meter long net bag, is operated in conjunction with a heavy net bucket frame for high towing rope speed during descent. For easy retrieval the sample is concentrated inside a removable plastic net bucket with side window (covered with sieve gauze).
The Indian Ocean Standard Net can be used in conjunction with one Mechanical Flow Meter with back-run stop for measurements of filtered water volume.
