SDN:B07::NDT024Epibenthic plankton net tow  
DEFINITION
  • A net system deployed from a ship, a sledge, a towed body, an autonomous submersible vehicle and towed close to the seabed. Usually horizontal tows, the sample or samples is/are collected while the gear is towed along the bottom of the sea and upward to 100 meters above the bottom. Most gears have opening and closing capability to avoid contamination during deployment or to collect separate discrete samples in a single deployment. Those towed from sledges originally did not have opening and closing capability, but many were modified later to collect discrete samples. These systems are designed to avoid catching sediment and associated bottom (benthic) fauna. For examples of gears using this type of deployment see Wiebe and Benfield 2003, Plates 6, 8 and 14.
