Detailed Description

Suite of borehole geophysical logs collected in an open mud-filled borehole at Jones Beach, New York.  The figure above shows a suite of borehole-geophysical logs collected by the USGS from an open mud-filled borehole (well N-13559) at Jones Beach, NY in May, 2006.  The gamma and electric logs help delineate the depth and thickness of the major clay and sand units found at this location, and indicate the amount of fines in the sediment, which helps in identifying variations within the hydrogeologic units.  In addition, the electric and conductivity logs indicate the presence of conductive (salty) groundwater in the upper glacial aquifer at this location.
