Received on January 1, 1981; accepted on March 1, 1981 The Undulating Oceanographic Recorder (UOR) Mark 2 is a self-contained oceanographic sampler which can be towed from research vessels and merchant ships at speeds up to 13.5 m. s–1 (26 knots). It can be launched and recovered by non-scientist crew-members while the vessel is undeT way. It is used to carry instrumentation to sample plankton continuously and to measure chlorophyll (range 0 to 100mg.m–3), radiant energy (range 0 to 1000µE.m–2.s–1) temperature (range 0 to 30°C) and salinity (range 32 to 37°/00), all of which are recorded, with the measurement of depth (range 0 to 100 m), by a miniature digital tape recorder, with a resolution of 0.1 %of full scale. The UOR Mark 2 has a towing speed range of 4 to 13.5 m.s–1 and it undulates from the surface to depths of 55 m (at 4 m.s–1) and 36 m (at 10 m.s–1) with 150 m of unfaired 8 mm od steel cable in water; the undulation length is pre-set between 800 and 4000 m. Used from a research ship, with 330 m of faired cable it reaches a depth of 240 m at a speed of 4 m.s–1. When towed with a conductor-cored steel cable, the vehicle can be controlled from the towing vessel and the data from the sensor measurements displayed on-board in real-time.
