Design and control of vector fields is critical for many visualization and graphics tasks such as vector field visualization, fluid simulation, and texture synthesis. The fundamental qualitative structures associated with vector fields are fixed points, periodic orbits, and separatrices. In this paper we provide a new technique that allows for...
Knowledge of the pelagic organisms in vast areas of the open ocean is very limited. This is particularly true of the small nekton or swimming forms such as fishes, squid, prawns and euphausiids, which are important as intermediate animals in the food chain and are preyed upon by species such...
The proposal for the research project reported herein was principally prepared during 1968 and the starting date for this study was established as September 1, 1969. In the approximately four years from the preparation of this proposal to the completion of this final report, the state of the art for...
This report deals with environmental strategies. Such strategies involve comprehensive and broad outlooks. In contrast, environmental tactics involve more limited concerns which can be usually addressed in a disciplinary or multi-disciplinary manner. The development of strategies necessitates interdisciplinary and transdisciplinary outlooks. Such outlooks are extremely difficult to achieve because different...
As part of the Willamette Basin Geographic Initiative Program, the Environmental Protection Agency (EPA) funded The Nature Conservancy of Oregon to inventory, classify, and map native wetland and riparian plant communities and their threatened biota in the Willamette Valley. Between October 1994 and September 1996, we evaluated 172 wetland and...

Marine Eco-Label Japan (MEL) is a unique Japanese seafood eco-labeling scheme launched in Japan shortly after the Marine Stewardship Council (MSC) opened its office to evaluate the management of Japanese fisheries resources by large-scale commercial fisheries and small-scale and diverse fishing gear. It became MEL ver. 2 and was approved...
Key Takeaway: Understanding this process and factors that influence compliance decisions can help support the development of effective regulations. Importance of consistent observer coverage. Compliance varied by violation choice. Importance of port-level campaigns.
This is a Biological Assessment (BA) addressing the potential effects on aquatic species currently listed or proposed for listing under the Federal Endangered Species Act (ESA) from the construction of the National Oceanic and Atmospheric Administration’s (NOAA) Marine Operations Center – Pacific (MOC-P) in Newport, Oregon. The MOC-P is proposed...
In this report, a response is given to the charge of this study. Volume I: Summary Report includes a synopsis of the technical considerations followed by the main findings and recommendations. The full technical background for these summary statements is given in detail in Volume II: Technical Background Report, and...
Concentrations of H₂O and CO₂ in olivine-hosted melt inclusions can be used to estimate crystallization depths for the olivine host. However, the original dissolved CO₂ concentration of melt inclusions at the time of trapping can be difficult to measure directly because in many cases substantial CO₂ is transferred to shrinkage...
The small-scale coastal fisheries of Virginia account for a significant portion of the state’s total annual landings and employ thousands of individuals. Despite the value of these fisheries, the number of commercial licenses sold has declined more than 15% since 1994. Declines are attributed to various factors, but indicate potential...
