The macer giroq supra benthic sled an improved device for quantitative 2 level sampling of the small swimming fauna near the bottom


, : The macer giroq supra benthic sled an improved device for quantitative 2 level sampling of the small swimming fauna near the bottom. Internationale Revue der Gesamten Hydrobiologie 63(6): 815-830

Enlarged versions of the Macer sled-mounted suprabenthic sampler were tested, improved, calibrated and used extensively (598 tows) at depths of 10-384 m since 1968 in the Gulf and Estuary of the St. Lawrence [Canada]. Two half-meter zooplankton nets were mounted at 28-64 and 106-142 cm from the sea-bed, on a steel chassis and toboggan plate. Each has a flow-meter and 3 horizontal shutters which open via a lever upon contact with the sea floor. They close automatically, through springs and water pressure, whenever the sled leaves the bottom, ensuring uncontaminated suprabenthic samples. Although heavy (228 kg), the device is sturdy, used like a beam trawl, reliable and collects very little sediment. It was used to study micro-stratification above bottom. Data on filtered water volumes, special problems encountered and future improvements were discussed.
