Bottom and sub-bottom mapping employ numerous marine geophysical techniques.

  • Bathymetry and side scan sonar surveys can be used to map the bottom of lakes, rivers, ponds and seas.
  • Sub-bottom mapping can identify layers' thicknesses and provide estimates of debris/sediment accumulation and bedrock depths.
  • Sediment sampling can be used to produce maps of bottom sediment types;
  • Underwater imaging can be used to produce maps of bottom vegetation and fish habitats.
