Borehole Geophysics

Borehole geophysics is the science of recording and analyzing measurements of physical properties made in wells or test holes. Probes that measure different properties are lowered into the borehole to collect continuous or point data that is graphically displayed as a geophysical log. Multiple logs typically are collected to take advantage of their synergistic nature--much more can be learned...

Surface Water-Quality Monitoring Network (WQN)

Overview

Pennsylvania’s Statewide Surface Water-Quality Monitoring Network (WQN) currently consists of 124 sites that are sampled between 6 and 20 times a year. Chemical analysis includes nutrient, major ions, and selected metals. Pesticide sampling is conducted twice a year at 5 locations. Biological sampling for benthic macroinvertebrates is conducted annually at 80 sites.

Chemical and physical controls on mercury source signatures in stream fish from the northeastern United States

Streams in the northeastern U.S. receive mercury (Hg) in varying proportions from atmospheric deposition and legacy point sources, making it difficult to attribute shifts in fish concentrations directly back to changes in Hg source management. Mercury stable isotope tracers were utilized to relate sources of Hg to co-located fish and bed sediments...
