WP3 net Ø113 cm


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 on request. We recommend a minimum of 200 µm.

(A) "Nansen release mechanism" (heavy duty version) for operating/closing plankton net by a 0,8 kg drop messenger.
(B) Three nylon lines (6 mm diameter) with bridle and snap hook (length: 85 cm).
(C) Ring of AISI 316 stainless steel tubing with 3 loops for bridle and weight lines, 2 loops for an optional digital counter located in the middle of the opening.
I.D. Ø113 cm = area of 1,0 m2.
(D) AISI 316 stainless steel clamping fixture.
(E) Part a net: 1000 µm Monodur Nytal (nylon) net with 6 loops for the 6 mm (diameter) nylon line closure rope. Cylindrical net length is 95 cm. Part b net is identical to a, but conically shaped. The length is 200 cm.
(F) AISI 316 stainless steel clamping fixture.
(G) Net bucket, based on the Hensen design. The bucket is made of a Polypropylene tubing, diameter 160 mm, with a plastic draining tap, 6 openings, (Total area of 315 cm²), covered by a 1000 µm net material of AISI 316 stainless steel, 1 round supporting rack bucket and 3 loops for lead weights.
(H) 3 Nylon lines for the weight with bridle and snap hook.

Net bucket:

is based on the Hensen design. The bucket is manufactured from a 160 mm (diameter) Polypropylene tubing with a plastic draining tap. The rack itself is made of AISI 316 stainless steel with a finish of electro polish.

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 standard delivery comes with 3 lead weights.





The net bucket supports up to 9 lead weights, each 2 kg.










For special purposes we can provide a closed bucket.

23.050 - Nansen releaser:

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.
