David P Krabbenhoft
David Krabbenhoft is a Scientist Emeritus with the Upper Midwest Water Science Center.
David Krabbenhoft received his Ph.D. from the University of Wisconsin-Madison in 1988 and has been a research scientist with the U.S. Geological Survey since. He has general research interests are in biogeochemistry and hydrogeology of aquatic ecosystems. Dave began working on environmental mercury cycling, transformations, and fluxes in aquatic ecosystems with the Mercury in Temperate Lakes project in 1988; since then, the topic has consumed his professional life. In 1994, Dave established the USGS’s Mercury Research Laboratory, which includes a team of multi-disciplinary mercury investigators and a state-of-the-art analytical facility strictly dedicated to low-level speciation analysis of mercury. In 1995 he initiated the multi-agency Aquatic Cycling of Mercury in the Everglades (ACME) project, which is still ongoing. More recently, Dave has been a Primary Investigator on the internationally conducted Mercury Experiment To Assess Atmospheric Loadings in Canada and the US (METAALICUS) project, which is a novel effort to examine the ecosystem-level response to loading an entire watershed with mercury. Currently, Dave’s research team is active on projects that span environments as far ranging as the Pacific Ocean to freshwater systems in Alaska to Florida, and from California to New England. In recent years, the Mercury Research Team entered into the realm of atmospheric research by constructing and deployed the USGS Mobile Atmospheric Mercury Lab, which has the capability for rapid deployment and advanced study of mercury in the atmosphere. Since 1990, he has authored or coauthored over 100 papers on mercury in the environment. In August 2006, Dave served as the Co-Chair for the 8th International Conference on Mercury as a Global Pollutant.

Applications of isotopes to tracing sources of solutes and water in shallow systems
New awareness of the potential danger to water supplies posed by the use of agricultural chemicals has focused attention on the nature of groundwater recharge and the mobility of various solutes, especially nitrate and pesticides, in shallow systems. A better understanding of hydrologic flowpaths and solute sources is required to determine the potential impact of sources of contamination on waterAuthorsCarol Kendall, David P. KrabbenhoftUse of oxygen-18 and deuterium to assess the hydrology of groundwater-lake systems
A thorough understanding of a lake's hydrology is essential for many lake studies. In some situations the interactions between groundwater systems and lakes are complex; in other cases the hydrology of a multilake system needs to be quantified. In such places, stable isotopes offer an alternative to the more traditional piezometer networks, which are costly to install and time-consuming to maintaiAuthorsDavid P. Krabbenhoft, Carl J. Bowser, Carol Kendall, Joel R. GatCycling of mercury across the sediment-water interface in seepage lakes: Chapter 13, Advances in Chemistry
The magnitude and direction of Hg fluxes across the sediment—water interface were estimated by groundwater, dry bulk sediment, sediment pore water, sediment trap, and water-column analyses in two northern Wisconsin seepage lakes. Little Rock Lake (Treatment Basin) received no groundwater discharge during the study period (1988—1990), and Follette Lake received continuous groundwater discharge. InAuthorsJames P.

More than three thousand kettle lakes, widely dispersed within a mixed temperate forest ecosystem, are predominant features of the Northern Highland area of north-central Wisconsin. A hydrological and biogeochemical investigation of seven of these lakes and their watershed area is currently in progress as part of the Water, Energy, and Biogeochemical Budgets (WEBB) program of the U.S. Geological SAuthorsJohn F. Elder, David P. Krabbenhoft, John F. WalkerData on water quality, lake sediment, and lake-level fluctuation, St. Croix Indian Reservation, Wisconsin, 1981-87
This report is a compilation of data on surface- and ground-water quality, lake sediment, and lake-level fluctuation collected by the U.S. Geological Survey (USGS) during 1981- 87 on or near the St. Croix Indian Reservation. The purpose of this report is to provide baseline data on selected aspects of the water resources of the St. Croix Indian Reservation as a referenceby which future hydrologicAuthorsD. P. Krabbenhoft, J. T. KrohelskiThe role of groundwater transport in aquatic mercury cycling
Mercury, which is transported globally by atmospheric pathways to remote aquatic environments, is a ubiquitous contaminant at very low (nanograms Hg per liter) aqueous concentrations. Until recently, however, analytical and sampling techniques were not available for freshwater systems to quantify the actual levels of mercury concentrations without introducing significant contamination artifacts.

A three-dimensional groundwater flow and solute transport model was calibrated to a plume of water described by measurements of δ18O and used to calculate groundwater inflow and outflow rates at a lake in northern Wisconsin. The flow model was calibrated to observed hydraulic gradients and estimated recharge rates. Calibration of the solute transport submodel to the configuration of a stable isotoAuthorsDavid P. Krabbenhoft, Mary P. Anderson, Carl J. BowserEstimating groundwater exchange with lakes: 1. The stable isotope mass balance method
Groundwater inflow and outflow contributions to the hydrologic budget of lakes can be determined using a stable isotope (18O/16O) mass balance method. The stable isotope method provides a way of integrating the spatial and temporal complexities of the flow field around a lake, thereby offering an appealing alternative to the traditional time and labor intensive methods using seepage meters and anAuthorsDavid P.

We measured groundwater velocity and submersed macrophyte biomass at 52 shal- low (0.4-6.6 m) sites in mesotrophic Sparkling Lake, Vilas County, Wisconsin, during May-Au- gust 1985. Seventeen percent of variation in macrophyte biomass was explained by a signifi- cant (P < 0.005) relation with depth [log(biomass + 1) = 0.49 depth - 0.08 (depth)2 + 0.121.
