We tested the role of benthic infaunal functional diversity in regulating the biogeochemistry of nearshore sediments using laboratory microcosms. Single and multispecies assemblages of deposit-feeding polychaetes (Clymenella torquata, Spio setosa, and Leitoscoloplos fragilis) were used, and fluxes of oxygen and phosphate, as well as profiles of oxygen and pH in...
Two idealized, three-dimensional, analytical models of middepth meridional overturning in a basin with a Southern Hemisphere circumpolar connection are described. In the first, the overturning circulation can be understood as a “pump and valve” system, in which the wind forcing at the latitudes of the circumpolar connection is the pump...
Report completed by the Workforce Capacity Work Group for the 2004 Oregon Fire Program Review. Technical editing by the Institute for Natural Resources at Oregon State University
The purpose of this report is to review existing wildfire prevention activities and recommend strategies to reduce the number and severity of human-caused wildfires in Oregon.
Oregon’s forest protection system was created in 1911. At that time, timber harvesting, forest management, and other land-clearing activities were the predominant uses of...
The thermobaric nonlinearity in the equation of state for seawater density—namely, the dependence of thermal expansibility on pressure—coupled with spatial variation of the oceanic temperature–salinity (θ–s) relation generates a nonlinear behavior in the buoyant force that can counter the linear dispersion of baroclinic Rossby waves and produce solitary waves. A...
