Field Activity 08LCA02

Identifier 08LCA02
Purpose The objective of this contract is to obtain HRMSRP and DC Resistivity profiles as applicable to the sites designated as Sentinel Lakes to characterize the subsurface of each water body. Of special concern is identifying discontinuities in the confining units between surface water and groundwater systems.
Location Central Florida Lakes
Summary CRP surveys were conducted in 8 lakes: Avalon, Cherry, Helen, Hiawassee, Johns, Louisa, Saunders and Sylvan. Land-based resistivity surveys were conducted in 3 lakes: Colby, Crooked, and Prevatt.
Info derived Resistivity techniques will be utilized to obtain information on geologic framework and composition in lakes identified in the project.
Comments Equipment: Advanced Geosciences, Inc. (AGI) Supersting R8/IP,100-m CRP cable (10-m electrode spacing) and Lowrance DGPS WAAS navigation for CPR system; AGI Supersting R8/IP and 112-m-long cable (2-m electrode spacing) for stationary DC Resistivity; Yellow Springs Instrument (YSI) 556MPS.
