Air–sea coupling during coastal upwelling was examined through idealized three-dimensional numerical simulations with a coupled atmosphere–ocean mesoscale model. Geometry, topography, and initial and
boundary conditions were chosen to be representative of summertime coastal conditions off the Oregon coast. Over the 72-h simulations, sea surface temperatures were reduced several degrees near...
Building community capacity is a central concern of both policymakers and community residents. Both want to understand why some communities are more successful in achieving positive social, economic and environmental outcomes, and how to increase the capacity of communities to achieve these outcomes. This is particularly true in communities that...
Vessel traffic places the sensitive environmental, natural, and cultural resources of Washington’s outer coast at risk of oil or hazardous materials spills. In 1995, International Maritime Organization established the Area to be Avoided off the Washington Coast (ATBA) to reduce this risk. Annual estimates of vessel compliance with the ATBA...
Satellite imagery has been a useful tool in monitoring land cover changes, including changes within protected areas. In the 1980’s and 1990’s Honduras created over 100 protected areas, yet few resources have been dedicated to their management. This study used Landsat satellite imagery to evaluate deforestation in the Río Plátano...
4-H members have the same responsibility for growing a safe, wholesome product as the livestock producer who sells hundreds of animals—and you must abide by the same laws. This publication can help you produce healthy project animals and ensure a safe, wholesome product for the consumer.
Learning how to produce...
This project examined a watershed council sponsored volunteer estuary water quality monitoring program, from initial implementation to program status five years later. In addition, literature research and interviews with estuarine experts were conducted in an attempt to devise strategies to strengthen estuary water quality monitoring programs within the state of...
A major benefit of bats in the garden is their appetite for insects. They consume about 50 to 100 percent of their body weight each day. Their favorite foods include garden pests such as beetles and moths. They also eat lots of mosquitoes, some of which carry diseases such as...
This study is the second in a series of studies to evaluate perceptions of USDA Forest Service law enforcement personnel of the roles, responsibilities, and issues entailed in their jobs. An e-mail survey was administered to the nine Forest Ser-vice special agents in charge (SACs) across the United States. All...
Silver scurf is caused by a fungus, Helminthosporium solani, a relatively new problem related to potato production in North America. It wasn’t until the early 1990s that this fungus was identified as being a serious problem in the Pacific Northwest. This fungus produces a surface blemish on tubers, causing them...
Tarif access and tree volume tables in this publication are for Douglas-fir, grand fir, ponderosa pine, red alder, western hemlock, and western redcedar. Tarif numbers range from 15 to 60, allowing you to estimate virtually any tree volume for the listed species, based on diameter at breast height (DBH) and...
This publication focuses on using water analyses to choose appropriate water treatment and water management practices for irrigated agriculture. It will help determine:
• What tests are needed to characterize water quality
• How to collect water samples
• How to interpret analytical data from a laboratory
• How to...
This study is the first in a series of studies to evaluate perceptions of USDA Forest Service law enforcement personnel of the roles, responsibilities, and issues entailed in their jobs. An email survey was administered to 404 law enforcement officers (LEOs) in national forests across the United States. In all,...

The Rural Science Education Program is a partnership between Oregon State University and rural K–12 schools for enrichment of the science curriculum with hands-on science activities. The curricula include simple, innovative inquiry- and site-based experiments that encourage critical thinking in K–12 students about the impacts of agriculture on the environment...
