Data are for high resolution seismic reflection experiment, using either Mini sosie or a 10 pound sledgehammer at seven sites in the Jacksonville area near existing wells. The primary reason for acquiring these daa was identification of karst features. Mini Sosie data acquiredwith 1 ms sample rate and record length 1024 ms each. Sledgehammer data acquired with .25 ms sample rate, record length 512 ms each. Sensor spacing ranged from 2-5 m for each array.
