The geophysical study was performed to characterize and quantify bottom and subbottom sediments in support of proposed maintenance dredging of the project areas. Two high resolution subbottom profiling systems were used to meet the primary project objectives. The survey results provide estimates of the sediment density, material type, and volume of material to be removed through dredging. In addition, the information supplements previously obtained soil borings by providing continuous profile line coverage of the subbottom sediments in each project area.
