The inter-relationships among δ¹³C and δ¹⁸O in tree ring cellulose and ring width have the potential to illuminate long-term physiological and environmental information in forest stands that have not been monitored. We examine how within-stand competition and environmental gradients affect ring widths and the stable isotopes of cellulose. We utilize...
Environmental contributions to cancer development are widely accepted, but only a fraction of all pertinent exposures
have probably been identified. Traditional toxicological approaches to the problem have largely focused on the effects of
individual agents at singular endpoints. As such, they have incompletely addressed both the pro-carcinogenic contributions
of environmentally...

The work reported herein was performed under the annual allotment from the Office of Water Resources Research to the Oregon Water Resources Research Institute. Funds were available over a three year period, but due to difficulty in acquiring graduate students, the total time spent on the project was only 21...
We present high-resolution measurements of carbon monoxide (CO) concentrations from a shallow ice core of the North Greenland Eemian Ice Drilling project (NEEM-2011-S1). An optical-feedback cavity-enhanced absorption spectrometer (OF-CEAS) coupled to a continuous melter system performed continuous, online analysis during a four-week measurement campaign. This analytical setup generated stable measurements...
Advances in trace gas analysis allow localised, non-atmospheric features to be resolved in ice cores, superimposed on the coherent atmospheric signal. These high-frequency signals could not have survived the low-pass filter effect that gas diffusion in the firn exerts on the atmospheric history and therefore do not result from changes...
