Fig. 4.

Grain-size data of surface sediment samples. For sampling positions see Figs. 2 and 3. (A) The first mode of grain size versus water depth, based on samples retrieved from seafloor type A, showing a decreasing first mode with increasing water depth. Samples 19 and 27, and 21 and 31 were taken at the same positions in 2008 and 2010, respectively. (B) The first mode of grain size versus water depth based on samples from seafloor types B, C and D show no correlation. (C) The grain size distribution of samples 5, 6, 7, 10, 12, 33 obtained from seafloor type A and H. All samples have the first mode at 2.4Φ.
