A JelNet is a plankton net system specifically designed to quantify fragile zooplankton ("jellies"). The net is 1.5m^2 at its opening and tapers to a shallow 50 cm deep flat bottom which has a collection "sock" to which a standard MOCNESS cod collar and end bucket were attached. Mesh size of the net is 5mm (3/16 inch). The square net frame is 16mm (5/8 inch) stainless steel and is bridled from each of the corners to a common point above by a 5mm (3/16 inch) stainless steel wire with thimbles spliced into the wire ends. A 45-kg lead ball is attached to a 13mm ( 1/2 inch) oblong stainless ring when the net is fished.
