L-31N Lithological and Geophysical Data provides hydrogeologic characterization of the Surficial aquifer underlying the L-31N Levee in Miami-Dade County, Florida. The dataset was created by the USGS, South Florida Water Management District, and the U.S. Army Corps of Engineers through on-site core description and downhole geophysical logging of boreholes. Data acquisition was completed by December 31, 2004.
Use Cases
- Delineate lithology and hydrostratigraphy from described core and sediment samples.
- Analyze aquifer properties using gamma ray, fluid conductivity, and EM-induction logs.
- Model groundwater flow with heat-pulse flow meter and fluid temperature measurements.
- Assess borehole conditions and sediment structure via 3-arm caliper and digital optical video logs.
Strengths
- Data includes multiple measurement types: lithological descriptions, gamma ray, fluid conductivity, temperature, EM-induction, caliper, sonic, flow meter, and video logs.
- Collection involved on-site USGS geologic expertise during drilling of four coreholes and the deepest wells in two clusters.
Limitations
- Dataset is temporally stale, with last update in 2004.
- Specific row counts, column details, and sample sizes are unknown.
- Geographic scope is limited to the L-31N Levee area in Miami-Dade County.
