Savannah Harbor Expansion Project (SHEP) Geophysical Survey

Hana performed an underwater geophysical survey of five areas encompassing 105 acres within the Savannah River to support the Savannah Harbor Expansion Project (SHEP). The surveyed area included portions of the main shipping channel that will be widened and deepened, as well as an area where the CSS Georgia, a Civil War battleship, was discovered. The survey was completed to determine whether any anomalies are present in the Savannah River that may pose a hazard to dredging operations. The geophysical survey included bathymetric survey using a multiphase echo sounder (MPES), side scan sonar (SSS) survey, and magnetic survey using Geometrics G-882 Transverse Gradiometer (TVG).
