Paired bongo nets

Fig. 1. Paired bongo nets are lowered on a wire to a depth of 500 meters. Lead weight suspended between the nets will hold them vertical in the water. Replicate samples of zooplankton will be caught as the nets are slowly pulled up through the water column. The mesh size (the size of the openings in the net fabric) is 150 microns (0.15 millimeters), so these nets catch tiny organisms. The mouth of each bongo net is 60 centimeters, so most fast-swimming animals will sense them coming and escape. Image courtesy of 2007: Exploring the Inner Space of the Celebes Sea.
