Long period (10–20,000 s) magnetotelluric (MT) data are being acquired across the continental USA on a quasi-regular grid of ∼70 km spacing as an electromagnetic component of the National Science Foundation EarthScope/USArray Program. These data are sensitive to fluids, melts, and other organic indicators, and thus provide a valuable complement...
A magnetotelluric (MT)transect has been obtained near latitude 45øN from the active Juan de Fuca
Spreading center, across the subduction zone and Cascades volcanic arc, and into the back arc Deschutes
Basin region. This paper presents the MT data set and describes its major characteristics as they pertain to
the...
Since the isolation of the Oregon sockeye salmon virus (OSV) in
1958, extensive investigations have been undertaken to characterize
the properties of this virus. The results of these investigations
have indicated that OSV is a single-stranded RNA virus which contains
essential lipids and has a density of 1.16 gm/cm³ in...
The usefulness of preplant nitrogen (N) in establishing
alfalfa in colder production areas has not been
well characterized. This study was conducted to determine
the effect of preplant N and soil temperature on
yield, percent N derived from biological nitrogen fixation
(PBNF), and shoot N concentration in alfalfa (Medicago
sativa...
A novel mode of shallow aquifer management could increase the volumetric potential and distribution of underground, freshwater storage: Shallow aquifer storage and recovery (SASR). In this mode, water is efficiently stored in basin fill aquifers with strong hydraulic connection to surface water. Regional numerical modeling can provide a linkage between...
Observed changes in climate of the U.S. Pacific Northwest since the early twentieth century were examined
using four different datasets. Annual mean temperature increased by approximately 0.6°–0.8°C from 1901 to
2012, with corroborating indicators including a lengthened freeze-free season, increased temperature of the
coldest night of the year, and increased...
This study examines productivity change in the Mid-Atlantic surfclam and ocean quahog fishery, which has been managed since 1990 using Individual Transferable Ouotas (ITQ). Productivity change is estimated through a Malmquist index from 1981-2008, capturing change before and after implementation of the quota system. We then decompose the index to...
A mesoscale model is used to examine the dynamics of northwest flow over the Santa Barbara Channel region.
Three cases are considered, each characterized by typical summertime synoptic conditions, but with differences
in pressure gradient strength and marine boundary layer depth (MBL). The first case examines a relatively deep
MBL...
Preservative treatment of whole, wood-based composite products (mainly panels) has disadvantages; problems largely stem from swelling, strength loss, and incomplete or inappropriate penetration during treatment, and distortion during redrying. Pretreatment of comminuted wood prior to mat lay-up is one alternative, though the addition of chemicals may affect bonding during subsequent...
