We are happy to present a viticulture-based newsletter this quarter, focusing on some of the challenges that were apparent in vineyard management during 2010. While the Botrytis challenges are fresh in the minds of vineyard managers, Walt Mahaffee provides a summary of a replicated field trial using Botrytis sprays. Vaughn...
Peppermint residue consists of the cooked leaves and stems of the peppermint plant after high-temperature distillation to extract oil. This residue has value as a soil amendment. It is often applied to fallow fields in the fall or sold as a soil amendment to gardeners. Research was conducted to determine...
In a series of Willamette Valley wetlands, standardized protocols were used in 2009 and 2010 to primarily assess (a) vegetation species composition and (b) relative levels of ecosystem services. Of the 60 wetlands visited in one or both years, 34 were classified as riverine and 26 as flats. Of the...
Remote sensing offers local, regional and global observations of seasonal snow, providing key information on snowpack processes. This brief review highlights advancements in instrumentation and analysis techniques that have been developed over the past decade. Areas of advancement include improved algorithms for mapping snow-cover extent, snow albedo, snow grain size,...
The Guano and Thousand-Virgin Sub-basins occupy over 1.8 million acres in Harney and Lake Counties in Oregon. The portions of the sub-basins in Nevada are not assessed in this document. Harney County Watershed Council (HCWC) watershed assessments focus on summarizing data from existing research, resource inventories, and management plans. This...
This report summarizes the presentations and discussions at the Regional Gravel Initiative Workshop. The Workshop was designed and conducted by the Institute for Natural Resources (INR) and Oregon Sea Grant (Sea Grant) on behalf of the U.S. Army Corps of Engineers (COE), the Oregon Department of State Lands (DSL) and...
Studies reporting on potentially toxic interactions between aqueous fullerene nanoparticles (nC₆₀) and
microorganisms have been contradictory. When known confounding factors were avoided, growth yields of
Saccharomyces cerevisiae and Escherichia coli cultured in the presence and absence of independently prepared
lots of underivatized nC₆₀ were found not to be significantly different.
The emerging picture of frontal scale air–sea interaction derived from high-resolution satellite observations of surface winds and sea surface temperature (SST) provides a unique opportunity to test the fidelity of high-resolution coupled climate simulations. Initial analysis of the output of a suite of Community Climate System Model (CCSM) experiments indicates...
Over the last three decades Oregonians have been engaged in a protracted discussion about Marine Spatial Planning. In the last twenty years the discussion has centered on the protection of Oregon’s natural marine resources and has taken on various labels such as marine gardens, conservation areas, marine sanctuary, and marine...
