Sediment Thickness Studies

Sediment thickness studies are typically performed to:

  • Identify and quantify offshore borrow pits
  • Survey sediment with channels
  • Pre/Post dredging surveys
  • Port expansions
  • Pipeline studies
  • Sand wave and Scour/Erosion Surveys

The studies are typically initially performed with a sub-bottom profiling system to produce a cross section of the seafloor and underlying sediments. Exact depths to layers of interest are verified using jet probes or vibracores. Sediment samples are taken with vibracores or ponar samples.
