Examples of repeated side-scan sonar surveys. The results focus on the sediment dynamics along a boundary of seafloor type A sediment patches (for positions, see Fig. 2. (A) Close to the coastline (water depths down to 10 m) the boundaries between the different seafloor types change in the order of tens of meters and are increasing (1), or decreasing (3), in coverage of type A sediments. Changes are observed also within the sediment patch (2). (B) Further offshore, observed changes are smaller. A change from silt to sand in the center of a type A sediment patch is marked with an arrow.
