Zunächst konnte in einem empirischen Ansatz aufgezeigt werden, dass zuverlässige Abundanzwerte einzelner Arten mit sehr unterschiedlichen Stichprobenzahlen erzielt werden. 
 The main goal of this study refers to the question as to how many samples are required to obtain representative figures of abundance and biomass of benthic organisms. At first, empirical approach resulted in quite different numbers of samples which are necessary for different species as well as for total abundance and total biomass. It is quite evident that the distribution pattern of the individual species plays an important role in this method.</gco:CharacterString></gmd:abstract><gmd:purpose><gco:CharacterString>Methodische
