A stalagmite (sample OCNM8-02A) collected from Oregon Caves National Monument (OCNM) was sampled for stable isotope ratios in order to develop a record of Pacific Northwest climate history. Nine U-series dates indicate that the record spans the time period - 13.5 - 9.5 ka. The stalagmite growth rate varied from...
Increased temperature and precipitation variability and frequent extreme weather events due to climate change pose a threat to farming operations and agricultural communities. The recent IPCC assessment shows that the projected climate change will, on average, reduce wheat yields by 5% in temperate regions without adaptation and even more if...
This PowerPoint presentation contains selected images pertaining to the topic of fire in Pacific Northwest forests—both wildfire and prescribed fire. Viewers are welcome to use this PowerPoint or any images contained therein. The material has been assembled during much of the author’s career, so proper attribution would be appreciated when...
PURPOSE: To determine physical, plankton and nutrient/chemical conditions over the continental
margin for climate change studies in NE Pacific. In particular, to make CTD and CTD/rosette and net
tow stations along 4 lines (off Newport, Coos Bay, Crescent City and Eureka), to make additional
stations along a fifth line (off...
Stocks of salmon are declining in the Pacific Northwest. Based on region-wide studies that list and categorize the status of salmon stocks (Nehlsen et al., 1991; Huntington et al., 1994; and Nawa, 1995), I analyze the watersheds where stocks of salmon spawn for several anthropogenic variables, most of which are...

Large fallen trees in various stages of decay contribute much-needed diversity of ecological processes to terrestrial, aquatic, estuarine, coastal beach, and open ocean habitats in the Pacific Northwest. Intensive utilization and management can deprive these habitats of large fallen trees. The publication presents sound information for managers making resource management...
