National and intergovernmental regulation of fisheries has not been sufficient to prevent many failures of fisheries management at the global scale. International trade in fisheries is of the order of USD 10 billion annually, mostly from “South” to “North”. Developing countries, particularly in Asia, benefit from this trade, and domestic...
BACKGROUND: Plant phenotype datasets include many different types of data, formats, and terms from specialized vocabularies. Because these datasets were designed for different audiences, they frequently contain language and details tailored to investigators with different research objectives and backgrounds. Although phenotype comparisons across datasets have long been possible on a...
An adiabatic calorimeter operating over the range 5 to 300 K has
been automated. Instrumentation includes computer controlled data
acquisition, a low-thermal emf multiplexer for switching low-level dc
signals, and automatic analog shield controls. Temperature
measurements are made with platinum and germanium resistance
thermometers, and the thermometer resistances are determined...
Considering human factors in early engineering design stages can improve expensive late stage processes, facilitate user safety, improve product quality and help reduce the need for physical prototyping. Currently, car pillar design (the vertical pillars between windows which connect the roof and car body) provide safety for the passengers in...
Mass wasting events are a principal form of erosion that occurs on steep forest land throughout the Pacific Northwest. Numerous studies have reported that tree roots help stabilize steep forest land. A complete
understanding of the mechanism by which roots strengthen soil would enable modeling to more closely approximate field...
The Oregon State University (OSU), Hydro Mechanical Fuel test Facility (HMFTF) is designed
to hydro-mechanically test prototypic plate type fuel. OSU’s fuel test program is a part of the
Global Threat Reduction Initiative (GTRI), formerly known as the Reduced Enrichment for
Research and Test Reactor program. One of the GTRI’s...
This article describes the results of numerical experiments carried out with a general circulation ocean model to investigate the effect of the seasonal cycle of the wind forcing on the Agulhas transport. Two cases are described. The first was initialized with temperature and salinity values obtained by horizontally averaging Levitus...
During the past 10 years the embryos and larvae of oysters and some species of clams have been employed to quickly assess the biological effects of various substances in marine water samples. The best materials have included some insecticides, herbicides, antibiotics, detergents, a variety of other compounds, and a few...
More than 7 km of long and relatively continuous sediment sequences
from 11 sites in the southeast and equatorial Pacific were recovered
during Leg 202 for the study of the Earth’s climate and biogeochemical
systems on scales that range from tectonic (millions of
years) to orbital (tens to hundreds of...
This article presents a semianalytic method to investigate the properties of energy transmission across bottom topography by barotropic Rossby waves. The method is first used to revisit the analytical estimates derived from wave-matching techniques and Wentzel–Kramers–Brillouin (WKB) approximations. The comparison between the semianalytic method and WKB indicates that the results...
Abundance, size and development stage data for furcilia and juvenile euphausiids and data on timing and prevalence of attached spermatophores on adult females are used to infer spawning times by four euphausiid species in Frederick Sound and lower Stephens Passage, Southeast Alaska. Results from net tows conducted between late May...
An inertial subrange was found in spectra calculated from vertical profiles of temperature gradient recorded in the bottom boundary layer of the Oregon shelf. Spectra were calculated for 53-cm vertical segments. An ensemble average of those spectra that were fully resolved and had high Cox number was compared to the...
Radiation damage caused by fission fragments to metal surfaces is an important research topic. Thin titanium foils were irradiated with a continuous wave beam of 132 MeV ¹³²Xe+²⁹ at the current intensity of 2 pnA. Pre- and post-irradiated surface topologies were investigated using atomic force microscopy and the observed defects...
In this article the authors examine the kinematics and dynamics of the seasonal cycle in the western Indian Ocean in an eddy-permitting global simulation [Parallel Ocean Circulation Model, model run 4C (POCM-4C)]. Seasonal changes of the transport of the Agulhas Current are linked to the large-scale circulation in the tropical...
