GEOPHYSICAL SAMPLES
CLICK ON IMAGE FOR DESCRIPTION
Arc Surveying & Mapping, Inc. provides geophysical surveys that describe the subsurface of marine environments.
Geophysical surveys are performed simultaneously with georeferenced bathymetry and provide a visual and digital understanding of subsurface structures utilizing Aquares, an advanced system that measures the resistivity of subsurface structures in Ohmm values.
Soft sediments will register low Ohmm resistance, while stiff clays and rock will register high resistance values.
Soft sediment layering is identified in the 3D Integrated Digital GroundModel (IDGM), enabling the identification of contaminated sediments with non-contaminated sediments and native bottom.
The model also provides a visual description of subsurface structures that is excellent for choosing boring geotechnical locations.
