Multiple measurements were conducted in the Mud Motor project (Baptist et al., 2019). Measurements of short-term sediment surface elevation changes are presented in the current dataset. Short-time surface elevation changes were determined with Surface Elevation Dynamics (SED) sensors. An extensive description with illustrations of this novel instrument is found in Hu et al. (2015). A SED-sensor is essentially a pin containing a semi-continuous array of 200 light sensitive cells that is inserted vertically in the sediment leaving approximately half of the measuring section above the seabed. The aboveground cells and belowground cells give high and low voltage outputs accordingly, resulting in a transition point at the bed level. The distance between two adjacent cells is 2 mm, and the measuring interval can be set from one second to a few hours, depending on the application. The measurement interval used in the current study was 30 min. The applied SED-sensors rely …
