Ground-water levels in selected well fields and in west-central Florida, May 1981
D. K. Yobbi, W. M. Woodham
1981, Open-File Report 81-1106
The water table in the surficial aquifer and the potentiometric surface of the Floridan aquifer in a 1,200-square-mile area in west-central Florida are mapped semi-annually by the U.S. Geological Survey. Maps are based on water levels measured in wells each May to coincide with seasonal low levels and each September...
Appearance and water quality of turbidity plumes created by dredging in Tampa Bay, Florida
Carl R. Goodwin, D.M. Michaelis
1981, Open-File Report 81-541
Turbidity plumes in Tampa Bay, Florida, were monitored during ship-channel dredging operations from February 1977 to August 1978 to document plume appearance and water quality, evaluate plume influence on the characteristics of Tampa Bay water, and provide a basis for transferring the information to other areas having generally similar sediment,...

Lithostratigraphy of the Silurian rocks exposed on the west side of the Cincinnati Arch in Kentucky
Warren Lee Peterson
1981, Professional Paper 1151-C
This report discusses the Silurian rocks that crop out in Kentucky west of the axis of the Cincinnati arch. The Silurian System has a maximum thickness in this outcrop area of about 190 feet. It is in most places separated from the underlying Ordovician System by a minor erosional unconformity....

Deformation of host rocks and flow of magma during growth of minette dikes and breccia-bearing intrusions near Ship Rock, New Mexico
Paul T. Delaney, David D. Pollard
1981, Professional Paper 1202
We have studied a small group of minette dikes and plugs that crop out within a flat-lying sequence of siltstone and shale near Ship Rock, a prominent volcanic throat of tuff breccia in northwestern New Mexico. Seven dikes form a radial pattern about Ship Rock we describe in detail the...
