The faunal composition, in terms of both the species pre
29、sent and their relative abundance, reflects integrated environmental conditions in the survey area over a period of time. The composition and structure of soft-bottom macrofaunal communities therefore can be used to characterize environmental conditions and estimate the extent of environmental impac
30、t.Characterization of environmental conditions is usually based on quantitative methods, in this case by relating the numbers of species and individuals captured to a known area of sea floor. For accurate data interpretation, it is essential to add information on the geophysicochemical characteristi
31、cs or properties of the water masses and bottom sediments, including nutrients, oxygenation, and redox state where appropriate.For effective data utilization and quality assurance (QA) of the work carried out, it is beneficial and may be essential (depending on the individual survey aims) that surve
32、ys be intercomparable temporally, spatially, and between operators. This International Standard contributes to ongoing work on QA of data from soft-bottom macrofaunal surveys. These guidelines primarily aim to assist in standardizing monitoring surveys carried out for commercial purposes or in conne
33、ction with the EU Water Framework Directive. For this reason, detailed specifications are given in areas of consequence for data intercompatibility.Where appropriate, costbenefit issues have been taken into consideration, and accepted minimal requirements for general environmental impact assessment
34、have been given. The cited minimum requirements for accuracy are not intended to satisfy research needs or to provide a full ecological understanding of the sampling area. Designers of programmes for research or other studies requiring a detailed knowledge of soft-bottom macrofauna should consult th
35、e guidelines given in Reference 13 for decisions on survey design and sampling frequency.This International Standard applies to all areas of the sea floor where it is possible to collect faunal samples by a grab or coring device. For practical reasons, this applies to animals retained on a mesh scre
36、en of 0,5 mm or 1 mm aperture size.The sensitivity of the method, here defined as detection of faunal disturbance, change in taxon composition or faunal mapping, is dependent on the survey design, the type of environmental influences present in the area and on the level of competence or standardizat
