A new quantitative sampler for the meiobenthos

Abstract

Abstract The meiobenthos, which comprises animals with a body length of approximately 0.2–2.0 mm, can be sampled quantitatively by means of a new untraditional grab which is described and figured. It cuts out a square of 150 cm2 of the upper 2–3 cm of the substratum and keeps the sample in a bag of nylon gauze. The instrument has worked successfully in continuous sampling in the øresund through 1 1/2 years.
