Abundances recorded by UWP were generally higher than those yielded by beam trawls, while taxa numbers were lower by UWP than by BT.For spatial and temporal variability of mega-epibenthic assemblages and taxa, seabed photographs were analysed for abundances and distribution patterns of solitary mega-epibenthic organisms and occurrences of biotope features. Correlations of taxa and assemblage distribution patterns with environmental factors were found at the different spatial and temporal scales.It was shown that UWP data contribute to the knowledge on ecology of the mega-epibenthos of the German Bight.eninfo:eu-repo/semantics/openAccessGerman Bightmega-epibenthosseabed photographyspatial variabilitytemporal variabilitymethodological comparison570Dissertationurn:nbn:de:gbv:46-diss000110957
