Continous Seismic-Reflection Survey Defining Shallow Sedimentary Layers in the Charlotte Harbor and Venice Areas, Southwest Florida

摘要

A continuous marine seismic-reflection survey system was used to define the configuration of shallow sedimentary layers underlying the Charlotte Harbor and Venice areas, southwest Florida. Seismic profiling was conducted over a distance of about 57 miles of Charlotte Harbor, the Peace and Myakka Rivers, and the Intraccoastal Waterway near Venice using a uniboom (high-resolution boomer) whose energy was capable of penetrating 200 feet of sediments with a resolution of 1 to 3 feet. Five stratigraphic units defined from the seismic records include sediments of Holocene to early Miocene age. All seismic-profile records are presented, along with geologic sections constructed from the records.
