This net is similar to the WP-2 net but larger.
The opening has a diameter of 113 cm (approx. 1 m²) and the conical net bag has a length of 200 cm.
Standard mesh size is 1000 µm. Other mesh sizes upon request. We recommend a minimum of 200 µm.
Net bucket, (G) based on the Hensen design. The bucket is manufactured from a 160 mm (diameter) Polypropylene tubing with a plastic draining tap.
The bucket has 6 openings with a total area of 315 cm². The windows are covered by a 1000 µm net which are protected by a larger net made of AISI 316 stainless steel, mesh size of 10 mm.
The bucket is equipped with 1 round supporting rack and 3 loops for lead weights.
All stainless steel has a finish of electro polish.
When pulling the WP-2 or WP-3 plankton net above the sea ground or in a specific height the Nansen releaser (A) will close the net at this particular depth to avoid intrusion of sediments from other depths.
The releaser is manually activated by the drop messenger.
