This report is an attempt to address some critical information gaps regarding the effects of dikes and tide gates on coastal ecosystems and fisheries resources. The authors have identified the information needs during their work with landowners, community organizations, and resource management agencies and through a compilation and summary of...
This document is intended for policymakers so they can make informed decisions about upgrading or removing tide gates in an effort to improve conditions for Oregon’s native migratory fish and other animals and plants that inhabit estuaries.
It has two main sections: The first includes an overview of the technical...
This document reports on findings, conclusions and recommendations derived from scientific literature and knowledge regarding the effectiveness of tide gate removal or upgrade in improving conditions for Oregon’s native migratory fish species, particularly salmonids, and other plant and animal species that utilize estuarine ecosystems. The project was commissioned by the...
This report assesses climate change impacts and associated community and ecosystem vulnerability. It was compiled by a group of Oregon State University researchers and students, outreach specialists, and coastal community members in Tillamook County, Oregon (OR). Through sustained engagement with the Tillamook County Coastal Futures Knowledge to Action Network (TCCF...
The surface-layer zone, occupying the upper 20 cm of the water column, represents a unique oceanic environment. A diverse assemblage of organisms occupies this zone, either in an obligate or facultative manner (Zaitsev 1970, Hempel and Weikert 1972, Cheng 1975, Peres 1982). Certain animals show morphological or biochemical adaptations to...
The School of Oceanography, Oregon State University, conducted three cruises (May 19-June 2, June 7-22, and September 4-14) in 1982 to study the distribution, abundance, migration, growth and feeding habits of juvenile salmonids during their first summer in the ocean. This is the second year we have had a series...
The report begins with a brief discussion of certain aspects of the production and consumption of Pacific Coast salmon. This is followed by a description of some structural characteristics of the market for canned salmon. The next section of the report reviews some of the earlier work on demand for...
This technical report summarizes the
results of a three year study of the zooplankton
living in the nearshore zone off
Newport, Oregon. The sampling program was
part of the Early Life History (ELH) project
of the Oregon State University Sea Grant Program
and was designed to study the ecology
of...
In this report, we build off of the knowledge and relationships created from the Seacast tool (2017) to explore the perceptions of uncertainty for both data providers and users. We then use the knowledge of these perceptions to derive metrics that address uncertainty which are acceptable to both parties. These...
Identification and classification of behavior states in animal movement data can be complex, temporally biased, time-intensive, scale-dependent, and unstandardized across studies and taxa. Large movement datasets are increasingly common and there is a need for efficient methods of data exploration that adjust to the individual variability of each track. We...
