The character of the primary seismic wave in the
range of distances between 100 and 600 km is affected by
such factors as the nature of the source, exponential
attenuation, crustal structure, type of wave propagation,
recording site geology and instrument response. The
first arrivals from the GNOME and SHOAL...
This publication describes raspberry cultivars, including red, yellow, black, and purple types. It explains the difference between floricane-fruiting and primocane-fruiting cultivars, includes information on commercial value, and identifies which cultivars work well for home gardens.
The Environmental Conditioning System (ECS) was designed to evaluate the
water sensitivity of asphalt concrete mixtures. The ECS subjects asphalt concrete specimens to a series of conditioning cycles including water flow, elevated and/or lowered temperature, and repeated axial loading. The purpose of this research was to: (1) evaluate the ECS...
The Grants Pass Batholith of Cretaceous age has intruded the
Triassic Applegate Group and metasedimentary rocks of the Jurassic
Galice Formation in the Murphy area of Josephine County, southwest
Oregon. The Applegate Group, mafic volcanic and sedimentary rock,
has been partially (nonequilibrium) metamorphosed under greenschist
facies conditions. The batholith, a...

conductance (EC), pH, temperature, and HCO3 were
measured on 43 samples of well water and Applegate River
Asphalt concrete pavement is subjected to several damaging actions from traffic
loads, water (from precipitation and/or groundwater sources), and temperature. The
durability of the asphalt-aggregate mixture, its ability to withstand these damaging
actions for long periods, is a very important engineering property. While the durability
of the asphalt-aggregates mixture depends...
Three stations, at ∼80 m water depth on the Oregon shelf between 44.7°N and 43.9 N, were studied under hypoxic conditions in late spring and summer of 2009 to determine benthic oxygen consumption rates. Oxygen fluxes were derived from eddy correlation (EC) measurements made from an autonomous lander deployed for...
Three stations, at similar to ~80 m water depth on the Oregon shelf between 44.7 degrees N and 43.9 N, were studied under hypoxic conditions in late spring and summer of 2009 to determine benthic oxygen consumption rates. Oxygen fluxes were derived from eddy correlation (EC) measurements made from an...
We sought to improve net ecosystem exchange (NEE) estimates for a tall, dense, mature Douglas-Fir forest in the Oregon Coast range characterized by weak flows, systematic wind directional shear, and limited turbulent mixing throughout the diurnal period. We used eddy covariance (EC) observations at two levels and concurrent biological measurements...
