Volcanic rocks from hotspots and island arcs/backarcs typically have enriched trace
element and isotopic compositions that contain a contribution from subducted oceanic crust.
Isotopic and trace element data suggest that the enriched components in hotspot volcanism
are ancient subducted sediment and crust, and the enriched components in arc/backarc
volcanism are...
Volcán Miño (21°11'S) is located on the westernmost periphery of a longlived complex of stratovolcarioes and domes called the Aucanquilcha Complex. The Aucanquilcha Complex ranges in age from 11 Ma to 1-lolocene and lies along the main N-S trending axis of Quaternary volcanoes in the Andean Central Volcanic Zone (CVZ)....
The Bransfield Strait is the narrow, late Tertiary to Quaternary marginal basin separating the South Shetland Islands from the northern end of the Antarctic Peninsula magmatic arc. Quaternary volcanism in the strait is tholeiitic to mildly alkaline, and contrasts chemically with the pre-Quaternary calc-alkaline arc volcanism. Geochemical evidence presented here...
We present the results of our experiments designed to extend the clinical applications of commercially available Optically Stimulated Luminescence (OSL) Dosimeters. Our initial experiments demonstrate the linear response of the OSL dosimeters for doses under 200 cGy and the non-linear response of the device after 200 cGy. Our experiments show...
Passive hydrophone technologies and a variety of acoustic methods are applied in
the deep-ocean and shallow water coastal environments of the northeast Pacific. A
catalog derived from U.S. Navy regional hydrophone array recordings of acoustic T- phases from seafloor earthquakes is examined, describing space/time patterns through
empirical orthogonal function analysis...
This study compares the production rates and yarding costs of prebunching
with a low investment skyline yarder and swinging with a larger
skyline yarder to full-cycle thinning with the larger yarder The study
analyzes two slackpulling techniques (manual and haulback assisted) and
two carriages (a multi-span carriage and a clamping...
Disease control is a crucial aspect of plant breeding for researchers as well as commercial producers. After samples from OSU's tomato breeding program tested positive for Columnea latent viroid in a screen done by a private company, secondary testing was done by the USDA laboratory in Corvallis which suggested that...
