1980, Open-File Report 80-587
A May 1980 potentiometric-surface map of the Southwest Florida Water Management District depicts the annual low water-level period. Potentiometric levels decreased 5 to 36 feet between September 1979 and May 1980, in the citrus and farming sections of southern Hillsborough, southwestern Polk, northwestern DeSoto , Hardee, and Manatee Counties. Water...

1980, Open-File Report 80-1068
Gravity data shown here were measured with LaCoste and Romberg sea gravimeter S-53 mounted on a 3 axis inertial platform (LaCoste and others, 1967, Valiant and LaCoste, 1976). Primary navigation was by satellite, integrated with course and speed measurements from doppler sonar and gyrocompass. Gravity data were filtered prior to...
Potentiometric surface maps of the Sparta Sand, northern Louisiana and southern Arkansas, 1900, 1965, 1975, and 1980

1980, Open-File Report 80-1180
The potentiometric surface of the Sparta Sand in northern Louisiana is shown by contours on four maps. Maps for 1900, 1965 , and spring 1975 are generalized, small-scale maps from previously published reports. The spring 1980 map (1:500,000) is based on measurements in 144 wells and includes the southern tier...
