Implication

Technical report demonstrates a horizontal multiple-net sampling system for zooplankton, indicating improved simultaneous capture of biological specimens and environmental data.

Key Points

Design and evaluate BIONESS, a horizontal multiple-net oceanographic sampler capable of gathering sequential biological specimens alongside synchronized physical environmental data.
Constructed a towable frame carrying ten 1.0-m² nets arranged horizontally rather than vertically, configured to open in sequence while towed at 3 knots.
Integrated real-time conducting cable telemetry linking the vessel with onboard sensors for temperature, conductivity, depth, illumination, and sampler attitude (pitch, roll, yaw).
Equipped the system with internal and external flowmeters to record filtered water volume and a strobe-lit 35-mm camera to photograph organisms in front of the mouth.
Operated ten sequentially triggered horizontal nets under continuous towing at 3 knots without net entanglement.
Enabled real-time, simultaneous collection of discrete micronekton and zooplankton samples paired directly with multidimensional physical oceanographic sensor profiles.
