Geophysical investigations were performed to
provide subsurface images using
400MHz, 270MHz, and 200MHz antennas with a
GSSI SIR 3000 GPR control unit.
Survey lines on Assateague Island showed
numerous textural features and potential
channel forms.
The 200MHz antenna provided the most
clear image of the subsurface at this site.
Channel forms, truncation of
bedding, crossbed structures and other
textural features were visible in the GPR
profiles
