Abstract | During two cruises in February and June of 2003, the erodibility of sediment along the western Adriatic Sea was measured using a "Gust erosion chamber". In addition, the surficial sediment properties were characterized through a suite physical and biological measurements including porosity, grain-size, inorganic carbon, organic carbon and colloidal carbohydrate. Comparisons were made between the sediment properties and erodibility to gain insight into the controls on sediment erodibility operating in the study area. Sediment erodibility along the western Adriatic sea varied both in time and space. Patterns of erodibility were governed primarily by physical factors in the wintertime and were possibly controlled by benthic biology in the summer. in particular, porosity and grain-size of surficial sediment were important factors controlling erodibility in the winter. In the summer, the controls on erodibility were variable, but evidence suggested that benthic microalgae were responsible for a decrease in sediment erodibility at one site. The possible impact of spatial changes in erodibility on patterns of sediment accumulation was explored. The results do not support the hypothesis that differences in erodibility are controlling where sediments accumulate along the western Adriatic sea. |
