Creator:: Finoff, David and Tschirhart, John
Abstract:: An important subset of natural resource management addresses preserving and/or harvesting biological resources. Examples are policies that derive from the Endangered Species Act including habitat conservation plans, the U.S. Forest Service’s logging practices, and fishery management councils’ decisions regarding catches. To understand the effectiveness of management policies requires an understanding...

Abstract:: Quality concerns drive many water studies and practices, but obtaining samples from water bodies over time and space for quality determination is often difficult and expensive. We present a low-cost approach that allows integration of water samples over timescales of days to months to allow more widely distributed acquisition of...

Abstract:: Solutions to the Boussinesq equation describing drainage into a fully penetrating channel have been used for aquifer characterization. Two analytical solutions exist for early- and late-time drainage from a saturated, homogeneous, and horizontal aquifer following instantaneous drawdown. The solutions for discharge Q can be expressed as dQ/dt = −aQ [superscript...

Abstract:: The Consortium of Universities for the Advancement of Hydrologic Sciences, Inc. (CUAHSI) began the Hydrologic Measurement Facility (HMF) program in June 2005 to advance hydrologic measurement capability within the research community. To provide guidance for this effort, a recent survey assessed the level of need among the hydrological sciences community...

Abstract:: Objectives: To evaluate the impact of the ring nematode, Mesocriconema xenoplax on the physiology and productivity of phylloxera-resistant grape rootstocks as a basis for recommending rootstocks in the Pacific Northwest. Specific objectives for 2006: Spring: Inoculate soil with AMF and M. xenoplax. Plant vines. Growing season: Monitor plant growth, gas...

Abstract:: Directly below commercial mint fields, percolation in excess of 10 ppm of nitrogen as nitrate (NO3 --N), the EPA drinking water standard, occurs for much of the year (Figure 1, page 2). Concentrations rise rapidly after irrigation starts in June, indicating that this nitrogen is being pushed through by irrigation...

Abstract:: Annual sprouting of aerial stems and ramets enables populations of salmonberry (Rubus spectabilis Pursh), salal (Gaultheria shallon Pursh), and probably other forest shrubs to maintain dense covers (>20 000 stems/ha). We studied annual stem production of salmonberry on cut (all stems cut within 15 cm of the ground) and uncut...

Abstract:: Hydrographic observations made with an undulating vehicle carrying a CTD and concurrent shipboard ADCP velocity observations over a 12‐day period are combined to investigate vertical mixing and cross‐frontal fluxes on the Northern Flank of Georges Bank. The CTD density time series is analyzed to detect the presence of vertical overturns,...

Abstract:: ’Teamaker’ hop (Humulus lupulus L.) (Reg. No. CV-28, PI 558864) was developed by the USDA-ARS as a unique, nonbittering, high beta-acids hop and was released on 26 June 2006. The defining characteristics of Teamaker are its near-zero percent alpha acids levels—a distinctive condition in the Humulus species (Haunold et al.,...
