Signals from the R/V Langseth’s tuned airgun array were recorded on an array of 33 EarthScope FlexArray seismometers deployed in the Oregon Coast Range from 43.5° to 45°N as part of the 2012 Ridge2Trench experiment to image the structure of the Juan de Fuca plate. This segment of the Juan...
For more than 30 years, researchers have investigated the effects of whole body vibration (WBV) platforms on athletic performance. WBV is a modality in which an individual stands on a vibrating platform to obtain performance effects. Frequency and amplitude of the vibration are the commonly adjusted parameters. The use of...
Many of the world’s most valuable fisheries involve highly migratory stocks that cross national jurisdictions. These same fisheries face severe threats from direct overfishing or excessive bycatch. Traditional input and/or output controls generally have been costly and ineffective. Incentive-based programs that provide tradable shares in an annual total allowable catch...
Billions of birds migrate at night over North America each year. However, few studies have described the phenology of these movements, such as magnitudes, directions, and speeds, for more than one migration season and at regional scales. In this study, we characterize density, direction, and speed of nocturnally migrating birds...
Several radioxenon isotopes (¹³¹ᵐXe, ¹³³Xe, ¹³³ᵐXe, ¹³⁵Xe) are characteristic byproducts of nuclear explosions, and due to their chemically nonreactive nature can easily escape from tests occurring underground and enter the atmosphere. It has been shown that by utilizing beta-gamma coincidence techniques, the Comprehensive Nuclear Test Ban Treaty Organization (CTBTO) can...
The Cackling goose (Branta hutchinsii minima) population has increased from a low of 20,000 in 1984 to the current population of 220,000-300,000 (Stehn 2012, Sanders 2013). As the Cackling goose population began to recover in the late 1990s, the majority of the population relocated from wintering in California to the...
