The primary goal of this study is to assess the impact of a subduction component
added to the mantle wedge beneath the Oregon Cascades to the composition and fO2 of
primitive Cascade basalts. Olivine-hosted melt inclusions from compositionally diverse
basalts across the Cascade arc (~100 km) are utilized in an...

Statistical summaries of streamflow data at 212 stream-gaging sites
are presented in this report to aid in appraising the hydrology of river
basins in Western Oregon. Records for 21 gaging stations were compiled
into separate periods owing to changes in regulation during the period
of data collection. The periods before...

Greater scientific knowledge, changing societal values, and legislative mandates have emphasized the importance
of implementing large-scale flow experiments (FEs) downstream of dams. We provide the first global assessment
of FEs to evaluate their success in advancing science and informing management decisions. Systematic
review of 113 FEs across 20 countries revealed...
