Abstract:
New seismic reflection data south of the Florida Panhandle and west of the Florida Peninsula, on the continental slope, were recorded by personnel from the Department of Oceanography, Texas A & M University, during January and May, 1967. These data correlate with earlier reflection and refraction results and indicate: (1) the anticlinal feature present along the top of the northern section of the West Florida escarpment, which may represent an extension of the Washita-Fredericksburg reef trend, can be followed as far south along the scarp as 27°00^primeN latitude and possibly farther; (2) the "scarp-face reflector" which has been traced under the abyssal plain sediments in the northeastern part of the basin can be followed toward the south to the latitude of Dry ortugas. In the southern section this reflecting horizon becomes "hummocky" and these highs and lows appear to be associated with the inundations present at the top of the scarp; and (3) the reflecting horizons believed to represent the Upper and Lower Cretaceous are identified on the slope as far south as 27°30^primeN. South of this latitude the character of the reflection records changes. This is interpreted to mean that the Tertiary section changes from predominantly clastic toward the northwest to mainly carbonate toward the southeast.
