The aim of these recommendations 1 is to standardize the methods used by different scientists for long-term benthos surveys, in order to increase the comparability of results for different areas and to enable, inter alia, detection of large-scale changes in the system that would not otherwise be detected by a single scientist. In these recommendations, soft bottoms are defined as those with sediments ranging from mud to, and including, sand. For descriptive surveys, macrofauna is defined as animals retained on a 1 mm sieve (mesh size 1 x 1 mm). However, if a finer sieve is used for some other purpose, the 1 mm sieve fraction should always be studied and reported separately to allow comparisons. For a more comprehensive treatment of sampling design, procedures, and alternatives, the reader is referred to, e.g., Kajak (1963), Cochran (1977), Elliott (.....
