Bongo net 2 x Ø30 cm

23.290 - Bongo net, 2 x 30 cm:

A bongo net consists of two plankton nets mounted next to each other. These plankton nets are ring nets with a small mesh size and a long funnel shape. Both nets are enclosed by a sample cylinder that is used for collecting plankton. The bongo net is pulled horizontally through the water column by a research vessel. Using a bongo net, a scientist can work with two different mesh widths simultaneously. Support of a V-fin depressor allows sample taking in various pre-defined depths.
