Current Research

Molecular Tracers of Contamination

As part of Stroud Water Research Center’s 6-year NY Watersheds Project, the objectives the Molecular Tracers group are to identify the sources and assess the magnitude of contamination to the watersheds that feed NY City’s drinking water supplies. At over 100 stream and river sites, we are analyzing the concentrations of 22+ organic compounds. These include caffeine, laundry detergent fragrances and fecal steroids, which act as indicators of waste water treatment plant effluent, septic system failure and pathogens that may come from human, agricultural, and wildlife sources. We also measure polyaromatic hydrocarbons (PAHs), which are known, petroleum and combustion byproducts, to track urban and suburban runoff. The spatial and temporal patterns of these contaminants will eventually provide a tool to help guide limited resources toward management of these watershed. Collaborators: Bernard Sweeney, Charles Dow, Louis Kaplan, John Jackson, Tom Bott and Denis Newbold.

Carbon Dioxide Outgassing from Tropical Rivers

We recently estimated that tropical rivers return about 1 gigaton per year of carbon as carbon dioxide to the atmosphere (see Publications, Richey et al. Nature, 2002). This flux nearly rivals the amount of carbon released annually by deforestation, and as such our findings have received considerable press (see USA Today, WhyFiles, and University of Washington press release). Our latest results (see Publications, Mayorga et al. Nature, 2005) show that this outgassing carbon dioxide is driven by respiration of terrestrial organic carbon that is less than five years old (see press release). We are currently conducting a broad survey of carbon dioxide concentrations in rivers of South America and South East Asia to better constrain the fluxes to the atmosphere and the ultimate sources of this carbon. Collaborators: Jeff Richey, Emilio Mayorga, Paul Quay, Alan Devol, Simone Alin (Univ. of Washington); Alex Krusche (CENA).

River Metabolism within the Amazon Basin

Continuing work initiated during Post-Doctoral research, we are examining results and samples from river water incubation experiments in order to explore factors that control organic matter degradation dynamics as a function of its elemental and biochemical composition by size class. Multiple hypotheses have been suggested in the literature, but this is the first study to examine several controlling factors simultaneously. In addition, these field experiments have been designed to provide important constraints on parameterization of a new “River basin Organic Matter and Biogeochemistry Synthesis” model (ROMBUS) that I am currently developing in conjunction with the Carbon in the Amazon River Experiment (CAMREX) group at the University of Washington. Collaborators: Ronald Benner (Univ. South Carolina); Alex Krusche (CENA).

Radiocarbon Constraints on Organic Matter Turnover in the Amazon River Basin

The objectives of this project are to: 1) Survey spatial and temporal variability in Δ 14C signatures of dissolved, fine particulate and course particulate organic carbon (DOC, FPOC and CPOC) and dissolved inorganic carbon (DIC) between basins of differing types and sizes; and to 2) Constrain age, turnover and pathways of these principal carbon fractions for the first phase of implementation and validation of a new “River basin Organic Matter and Biogeochemistry Synthesis” model (ROMBUS). Collaborators: Emilio Mayorga, John Hedges and Jeff Richey (Univ. of Washington); Carrie Massiello and Tom Brown (Center for Accelerator Mass Spectrometry).

Competition for Organic Molecules by Biodegradation and Sorption to Minerals

In the environment, the composition natural organic matter is largely determined by its interactions with heterotrophic microorganisms and with mineral surfaces. Both biodegradation and sorption processes are highly selective — some molecules and molecular classes are degraded and sorbed in preference to others. The question thus arises as to what the interplay is between these two processes in determining organic matter composition, turnover and transport. Collaborators: John Hedges (Univ. of Washington).

Compositional Evolution of Dissolved Organic Matter in Rivers

If biodegradation and sorption together determine the molecular composition of organic matter, what might be the expected compositional trends downstream in a river system largely devoid of fine minerals (Rio Negro, Brazil) versus one that carries high suspended mineral loads (Rio Solimoes, Brazil). We are exploring the use of one and two dimensional liquid state NMR to explore trends in organic matter composition within these two river systems. Collaborators: Norbert Hertkorn and Philippe Schmitt (GSF); John Hedges (Univ. of Washington).
