| Abstract |
1. A new bottom sampler for macrofauna is described which is easily operated by a diver.2. The airlift pump principle is employed firstly to sink a sampling cylinder into the seabed and secondly to operate a suction pipe which is used to excavate sand and animals from within the cylinder.3. The sampler covers an area of 0.1 m2 and penetrates to a depth of 60 cm. It is particularly suitable for quantitative studies of deeper burrowing fauna (e. g.Ensis spp. andLutraria spp.).4. The sampler is designed for use in sandy sediments and for studies on the distribution of faunas within small areas where line transects or grids of samples are required. |
