High variability of bioturbation on different spatial scales with regard to the distribution and intensity of local and non-local transports with an increase of non-local biotubration towwards the east was estimated. The depth distribution of the macrozoobenthos within the sediment explained these bioturbation patterns, determined key species and gave evidence for the superior role of the fauna on particle transport. Food supply and local transports corrleated negatively and non-local processes depend on the number of...
