Severe droughts occurred in the western United States during recent decades, and continued human greenhouse gas emissions are expected to exacerbate warming and drying in this region. We investigated the role of water availability in shaping forest carbon cycling and morphological traits in the eastern Cascade Mountains, Oregon, focusing on...

We present multiple lines of evidence for years to decade-long changes in the location and
character of volcanic activity at West Mata seamount in the NE Lau basin over a 16 year period, and a hiatus
in summit eruptions from early 2011 to at least September 2012. Boninite lava and...

Eruptive modes and hiatus of volcanism
Firn air transport models are used to interpret measurements of the composition of air in firn and bubbles trapped in ice in order to reconstruct past atmospheric composition. The diffusivity profile in the firn is usually calibrated by comparing modelled and measured concentrations for tracers with known atmospheric history. However,...

Using a low-energy, three stage, differentially pumped ion
accelerator, similar to that used by Hagstrom for Auger electron
ejection studies, permits, with the application of radiotracer methods,
a new approach to the study of low energy sputtering.
The experimental approach consisted of pumping down the
experimental tube to 10⁻⁹ torr,...
Pleuropogon oregonus Chase is a rare wetland grass endemic to eastern Oregon. The species is composed of two widely separated populations, one in Lake County and one in Union County. In order to reduce the risk of extinction, the Oregon Department of Agriculture Native Plant Conservation Program initiated several reintroduction...
A modified agar overlay technique for the preliminary screening
of antibiotic producing Streptomyces spp. has been developed and
compared to the routinely used shake flask method and the
unmodified agar overlay technique. The percentage of isolates
exhibiting antimicrobial activities was found to be greater in the
modified overlay technique.
Three...
The experimental measurements of the decay heat from
the products of the thermal fission of U-235 have been compared
with the OSU-proposed decay heat standard. These experiments
are intended to verify the decay heat calculational
methods and nuclear data files. The comparisons have
included the previous experiments reviewed by Perry...
