Figure 7. Seismic reflection profile and interpretation, line PB-96-21, Rockland Harbor made with an ORE Geopulse. Survey made around 9:25 AM 6/26/96 from the Research Vessel Lee. Time event/marks on the original data and interpretation correspond to numbers along the A - B line on the map. (A) Seismic reflection profile shows a strong reflector below sea floor. (B) Interpretation of profile in (A). Sub-bottom bedrock surface is irregular, thus sediment above bedrock is a different thickness from place to place. The thickest sediment is near points 28 and 30. (C) Map showing location of the offshore seismic reflection profile. Notice that points 28 and 30 are offshore from coastal embayments.
