Pierre Glynn, Ph.D.
Pierre Glynn, Ph.D., has now retired from his USGS management positions and is devoting his time to conducting interdisciplinary research to advance the science, policy, and management of complex systems and issues. He is currently Emeritus Scientist with the USGS Science and Decisions Center (USGS/SDC) in the Northeastern Region.
Pierre also serves as an Affiliated Scholar with Arizona State University’s Consortium for Science, Policy and Outcomes (ASU/CSPO) in Washington D.C.
Pierre’s current research includes studies on:
- water and natural capital accounting (USGS/SDC),
- value of Information – useability and actionability (USGS/SDC),
- Chesapeake Bay watershed modeling and its associated social systems (USGS/SDC),
- examining the role of narratives and information in managing natural resources and societal hazards (ASU/CSPO),
- adaptive management, participatory modeling, public participation in science, and the creation of “Records of Engagement and Decision-Making” (mainly ASU/CSPO),
- integrated modeling and System of Systems modeling (USGS/SDC), and
- the role of human biases, beliefs, heuristics, values, and norms in the conduct of science and policy (USGS/SDC).
Pierre was recently awarded (through ASU/CSPO) a Catalyst Leaders Fellowship from the Royal Society of New Zealand to study water science and policy issues (centered around Lake Taupo) in collaboration with the Institute of Geological and Nuclear Sciences (GNS Science, New Zealand).
Pierre’s academic background includes a B.A. in Geological Sciences from Columbia College, an M.Sc. from University of Quebec in Montreal in isotopic environmental geochemistry, and a Ph.D. from the University of Waterloo, where his studies focused on groundwater and geochemical modeling.

The U.S. Geological Survey (USGS) is a multidisciplinary agency that provides assessments of natural resources (geological, hydrological, biological), the disturbances that affect those resources, and the disturbances that affect the built environment, natural landscapes, and human society. Until now, USGS map products have been generated and distributed primarily as 2-D maps, occasionally providiAuthorsLinda J. Jacobsen, Pierre D. Glynn, Geoff A. Phelps, Randall C. Orndorff, Gerald W.

Over nearly two decades, the Water, Energy, and Biogeochemical Budgets (WEBB) small watershed research program of the U.S. Geological Survey (USGS) has documented how water and solute fluxes, nutrient, carbon, and mercury dynamics, and weathering and sediment transport respond to natural and humancaused drivers, including climate, climate change, and atmospheric deposition.

The U.S. Department of Energy (DOE) requested that the U.S. Geological Survey conduct an independent technical review of the Interim Risk Assessment (IRA) and Contaminant Screening for the Waste Area Group 7 (WAG-7) Remedial Investigation, the draft Addendum to the Work Plan for Operable Unit 7-13/14 WAG-7 comprehensive Remedial Investigation and Feasibility Study (RI/FS), and supporting documentsAuthorsJoseph P.

Geochemistry has contributed significantly to the understanding of ground-water systems over the last 50 years. Historic advances include development of the hydrochemical facies concept, application of equilibrium theory, investigation of redox processes, and radiocarbon dating. Other hydrochemical concepts, tools, and techniques have helped elucidate mechanisms of flow and transport in ground-watAuthorsPierre D. Glynn, Niel PlummerModeling ground-water flow and quality

Questions of major importance for subsurface contaminant transport at the Idaho National Engineering and Environmental Laboratory (INEEL) include (i) travel times to the aquifer, both average or typical values and the range of values to be expected, and (ii) modes of contaminant transport, especially sorption processes.

Large-scale mining activities have generated a plume of acidic ground water more than 15 km long in the regional aquifer of the Pinal Creek Basin. A one-dimensional reactive-transport model was developed using PHREEQC to aid in the analysis of transport and chemical processes in the plume and to determine the uses and limitations of this type of modeling approach. In 1984, the acidic part of the pAuthorsJames G. Brown, R. L. Bassett, Pierre D. GlynnPHRQCGRF, a computer program for graphical interpretation of PHREEQC geochemical transport simulations (PC only)

Stable isotopic ratios of C and H in dissolved CH4 and C in dissolved inorganic C in the ground water of a crude-oil spill near Bemidji, Minnesota, support the concept of CH4production by acetate fermentation with a contemporaneous increase in HCO3−concentration. Methane concentrations in the saturated zone decrease from 20.6 mg L−1 to less than 0.001 mg L−1 along the investigated flow path. DissoAuthorsKinga Revesz, Tyler B. Coplen, Mary J.

In reply to the Critical Comment of R. K. Stoessell (this issue), limiting activity coefficients of bromide in halite (γNaBr) have been calculated by least-squares fitting of Simons et al.'s (1952) bromide distribution coefficient data for the Na(Cl,Br)-NaOH-H2O system at 35°C. Regular and subregular solidsolution model fits give γNaBr = 7.4 and γNaBr = 8.8, respectively. The Br contents of haliteAuthorsPierre D. Glynn, Eric J. Reardon, Niel Plummer, Eurybiades Busenberg
