| Definition | A modified version of the LHPR . A tubular frame 185 cm high x 125 cm wide x 640 cm long and with a 81 cm expanding to 100 cm diameter nose cone was used with a recorder box (with 1.55 mm nylon mesh gauze) attached to the cod-end of a conical net 300 cm long with same mesh. The mouth of the recorder box is equipped with an opening/closing unit which shunts water flowing through the net to the open sea when closed and into the recorder when open. System acoustically (IOS) telemeters depth, flow, and temperature and controls recorder box opening/closing unit. Underwater electronics records temperature, depth, flow, and controls gauze advance. Designed to tow up to 4 knots [Wiebe and Benfield 2003 Plate 27 B]. | ||
