James B. Shanley, K. Niclas Hjerdt, Jeffrey J. McDonnell, Carol Kendall
2003, Groundwater (41) 964-972
Hydrologic modeling of catchments is frequently hampered by lack of information on subsurface stratigraphy and zones of preferred flow. We evaluated the usefulness of soil penetration resistance, easily measured by a dynamic cone penetrometer, together with measurements of ground water level fluctuations, as a cost-effective means to infer subsurface flow...

Mark Marvin-DiPasquale, Jennifer L. Agee
2003, Estuaries (26) 1517-1528
Microbial mercury (Hg) methylation and methylmercury (MeHg) degradation processes were examined using radiolabled model Hg compounds in San Francisco Bay-Delta surface sediments during three seasonal periods: late winter, spring, and fall. Strong seasonal and spatial differences were evident for both processes. MeHg production rates were positively correlated with microbial sulfate...

Heat as a tool for studying the movement of ground water near streams
David A. Stonestrom, Jim Constantz, editor(s)
2003, Circular 1260
Stream temperature has long been recognized as an important water quality parameter. Temperature plays a key role in the health of a stream’s aquatic life, both in the water column and in the benthic habitat of streambed sediments. Many fish are sensitive to temperature. For example, anadromous salmon require specific...
