| Popis: | This study presents benthic data from 12 samplings from February to December 2010 in a 2 m deep channel in the southwest Baltic Sea. In winter, the distribution of solutes in the porewater was strongly modulated by bioirrigation which efficiently flushed the upper 1 cm of sediment, leading to concentrations which varied little from bottom water values. Solute pumping by bioirrigation fell sharply in summer as the bottom waters became severely hypoxic ( |
