The area was surveyed using 3km long parallel tracks, 250m apart. Acoustic mapping using the RoxAnn system provides data on the physical nature of the sea bed - depth, roughness and hardness. The acoustic data have no biological meaning unless they are related to biological assemblages, determined from direct observations or samples of the sea bed at pre-determined point locations. Thus sub-tidal grab samples and video drops were taken within the survey area. Nature conservation Environment Agency, 1998. Durham Coast Project, ?Turning the Tide?
