in a bay setting devoid of fishing and strong near-bed 
tidal currents. 
The fine-sand seabed of the study site allows for the 
formation of relatively shallow dredge scars. The lim- 
ited seasonal time scale for discernibility of the dredge 
scars is due to ongoing fishing efforts that rework the 
surface sediment and the reworking of sediment from 
wave driven near-bed currents. As such, side-scan sur- 
veys at our study sites can be a useful tool for quanti- 
fying fishing effort but only for a current season.
