Christopher Fuller
Christopher Fuller is a Emeritus Scientist for the USGS Water Resources Mission Area. His research characterizes processes and mechanisms of metal sorption reactions through field studies and lab experiments to better understand the metal transport and natural attenuation in mine contaminated systems and to better understand geochemical processes affecting bioavailability of metal contaminants to aquatic organisms.

Surface chemistry of ferrihydrite: Part 2. Kinetics of arsenate adsorption and coprecipitation
The kinetics of As(V) adsorption by ferrihydrite was investigated in coprecipitation and postsynthesis adsorption experiments conducted in the pH range 7.5-9.0. In coprecipitation experiments, As(V) was present in solution during the hydrolysis and precipitation of iron. In adsorption experiments, a period of rapid (<5 min) As(V) uptake from solution was followed by continued uptake for at least eAuthorsC. C. Fuller, J.A. Dadis, G.A. WaychunasSurface chemistry of ferrihydrite: Part 1. EXAFS studies of the geometry of coprecipitated and adsorbed arsenate
EXAFS spectra were collected on both the As and Fe K-edges from samples of two-line ferrihydrite with adsorbed (ADS) and coprecipitated (CPT) arsenate prepared over a range of conditions and arsenate surface coverages. Spectra also were collected for arsenate adsorbed on the surfaces of three FeOOH crystalline polymorphs, α (goethite), β (akaganeite), and γ (lepidocrocite), and as a free ion in aqAuthorsG.A. Waychunas, B.A. Rea, C. C. Fuller, J.A. DavisEvidence from Cd/Ca ratios in foraminifera for greater upwelling off California 4,000 years ago
UPWELLING of nutrient-rich Pacific deep water along the North American west coast is ultimately driven by the temperature difference between air masses over land and over the ocean. The intensity of upwelling, and biological production in the region, could therefore be affected by anthropogenic climate change. Examination of the geological record is one way to study the link between climate and upAuthorsA. VanGeen, N. Luoma, C. C. Fuller, R. Anima, H. E. Clifton, S. TrumboreDistribution and transport of sediment-bound metal contaminants in the Rio Grande de Tarcoles, Costa Rica (Central America)
A reconnaissance survey of the extent of metal contamination in the Rio Grande de Tarcoles river system of Costa Rica indicated high levels of chromium (Cr) in the fine-grain bed sediments (<60 μm) of tributaries downstream from leather tanneries (50–83 times Cr background or 3000–5000 μg/g). In the main channel of the river downstream of the San Jose urban area, Cr contamination in sediments wasAuthorsC. C. Fuller, J.A. Davis, D.J. Cain, P. J. Lamothe, T.L.G. Fries Fernandez, J.A. Vargas, M.M. MurilloInfluence of coupling of sorption and photosynthetic processes on trace element cycles in natural waters
Chemical and biological processes have important roles in the transport and cycling of trace elements in natural waters, but their complex interactions are often not well understood. Trace-element concentrations may, for example, be controlled by adsorption-desorption reactions at mineral surfaces, with the equilibrium strongly influenced by pH. Variations in pH due to photosynthetic activity shouAuthorsC. C. Fuller, J.A. DavisA model for trace metal sorption processes at the calcite surface: Adsorption of Cd2+ and subsequent solid solution formation
The rate of Cd2+ sorption by calcite was determined as a function of pH and Mg2+ in aqueous solutions saturated with respect to calcite but undersaturated with respect to CdCO3. The sorption is characterized by two reaction steps, with the first reaching completion within 24 hours. The second step proceeded at a slow and nearly constant rate for at least 7 days. The rate of calcite recrystallizatiAuthorsJ.A. Davis, C. C. Fuller, A.D. CookProcesses and kinetics of Cd2+ sorption by a calcareous aquifer sand
The rate of Cd2+ sorption by a calcareous aquifer sand was characterized by two reaction steps, with the first step reaching completion in 24 hours. The second step proceeded at a slow and nearly constant rate for at least seven days. The first step includes a fast adsorption reaction which is followed by diffusive transport into either a disordered surface film of hydrated calcium carbonate or inAuthorsC. C. Fuller, J.A. DavisSediment accumulation in San Leandro Bay, Alameda County, California, during the 20th century -- A preliminary report
Major changes made in the configuration of San Leandro Bay, Alameda County, California, during the 20th century have caused rapid sedimentation within parts of the Bay. Opening of the Oakland tidal channel and removal of 97% of the marshlands formerly surrounding the Bay have decreased tidal velocities and volumes. Marshland removal has decreased the tidal prism by about 25%. Comparison of bathymeAuthorsK. M. Nolan, C. C. FullerBenthic fluxes in San Francisco Bay
Measurements of benthic fluxes have been made on four occasions between February 1980 and February 1981 at a channel station and a shoal station in South San Francisco Bay, using in situ flux chambers. On each occasion replicate measurements of easily measured substances such as radon, oxygen, ammonia, and silica showed a variability (??1??) of 30% or more over distances of a few meters to tens ofAuthorsDouglas E.

The deposition rate of atmospheric Pb-210 has been measured during a one year period using plastic funnels as collectors. Observed rates were 0.15 dpm cm−2 yr−1 at a site in Palo Alto, California and 0.21 dpm cm−2 yr−1 at a site in Los Angeles. The Palo Alto value agrees well with a long-term average of 0.14 dpm cm−2 yr−1, obtained from a nearby salt marsh core. These rates are only one-third of tAuthorsChristopher Fuller, Douglas E.
