Description: 
High resolution seabed maps of Pillar Bank survey area showing bathymetry data (left panels) and acoustic backscatter data (right panels) with sample sites. Close-up maps of seabed features include: (A) An area of raised irregular hardground; (B) Ridges of hardground that rise 40 m above the surrounding sediment plain; (C) An area of dense pockmarks formed in soft sediment; (D) A flat-topped platform with deep tidal scour holes at its base. Note: backscatter is a measure of relative hardness of the seabed, with high backscatter indicating harder seabed (such as rock).
