Title: Continental Slope Off Southwest Florida

Author(s): G. F. Jordan, H. B. Stewart, Jr. (2)


Recent surveys of the west Florida continental slope made by the Coast and Geodetic Survey show for the first time the detailed topography of the southern part of this area. A marked change in topography at 27° North latitude separates the northern from the southern part of the slope and is related to north-to-south changes from clastic to non-clastic underlying bedrock and from thick to thin or non-existent overburden of unconsolidated sediments.

A drowned barrier spit and lagoon unchanged by subsequent erosion or deposition were revealed at 75-100 fathoms. These features are described and discussed along with numerous long breaks in slope, embayments, and offsets in the steep lower slope, reef patches, dome-like structures, and spur-shaped ridges.
