Petis Bois model

Detailed Description

A perspective model of the morphology and geologic framework near Petit Bois Island showing the relationships between seafloor features and the subsurface. The barrier islands rest on the island plaftorm. Petis Bois Pass and offshore shoals are clearly visible from the acoustic surveys. The bathymetry, sidescan sonar, and sediment cores provide information about the extent and texture of the seafloor features. In the subsurface, positions of various features, such as buried channels, can be seen relative to the seafloor morphology.
