Benthic Habitat Mapping: eCognition Rule Set

Creator:: O’Neil-Dunne, Jarlath P. M., Parrish, Christopher E., and Dijkstra, Jennifer A.
Abstract:: This publication consists of a rule set for benthic habitat classification implemented in eCognition (Trimble Navigation Limited). The details of the procedure are described in Parrish et al., 2016: http://www.jcronline.org/doi/abs/10.2112/SI76-017. The input to the classification consists of high-resolution true color orthophotos, seafloor DEMs from topobathymetric lidar, and gridded lidar reflectance...

Double-Ended Calibration of Fiber-Optic Raman Spectra Distributed Temperature Sensing Data

Creator:: van de Giesen, Nick, Steele-Dunne, Susan C., Jansen, Jop, Hoes, Olivier, Hausner, Mark B., Tyler, Scott, and Selker, John
Abstract:: Over the past five years, Distributed Temperature Sensing (DTS) along fiber optic cables using Raman backscattering has become an important tool in the environmental sciences. Many environmental applications of DTS demand very accurate temperature measurements, with typical RMSE < 0.1 K. The aim of this paper is to describe and...

New insights on an old topic : understanding the effects of forest harvest on trout in the context of climate

Creator:: Penaluna, Brooke E.
Abstract:: Studies of the effects of forest harvest on streams and fish have a long history in the Pacific Northwest. Results of this work have prompted development of new forest harvest practices that are more protective of these resources, but the effectiveness of these new practices has not been fully evaluated....

Structural Variations of Headwater Stream Food Webs Along Geophysical Gradients at the HJ Andrews Experimental Forest

Creator:: Zatkos, Lauren E.
Abstract:: The structure of food webs and how they relate to community stability has been an important debate in ecology. Specifically, predictability of web shape and how it influenced by surrounding landscapes is one of the main goals of such discussions. Headwater streams provide a study template that is of interest...

Distribution of juvenile salmonids and stream habitat relative to 15-year-old debris-flow deposits in the Oregon Coast Range

Creator:: Kirkby, Kristen-Marie S.
Abstract:: Debris flows, common disturbances in many mountainous areas, initially scour or bury stream habitats; however, debris flows deliver vast amounts of wood, boulders, and gravel that may ultimately form complex stream habitat to potentially support a diverse salmonid assemblage. The materials deposited by debris flows would otherwise be inaccessible to...

Biophysical Effects and Ground Force of the Baldree Traffic Simulator

Creator:: Kowalewski, A. R., Schwartz, B. M., Grimshaw, A. L., Sullivan, D. G., Peake, J. B., Green, T. O., Rogers, J. N., III, Kaiser, L. J., and Clayton, H. M.
Abstract:: Traffic simulators are often utilized when researching turfgrass wear tolerance and recovery. However, the availability of a durable traffic simulator capable of producing dynamic force is limited. Therefore, the objectives of this research were to: 1) evaluate a novel traffic simulator with improved durability and capable of producing dynamic force...

Global solutions to regional problems : collecting global expertise to address the problem of harmful cyanobacterial blooms. A Lake Erie case study

Creator:: Bullerjahn, George S., McKay, Robert M., Davis, Timothy W., Baker, David B., Boyer, Gregory L., D’Anglada, Lesley V., Doucette, Gregory J., Ho, Jeff C., Irwin, Elena G., Kling, Catherine L., Kudela, Raphael M., Kurmayer, Rainer, Michalak, Anna M., Ortiz, Joseph D., Otten, Timothy G., Paerl, Hans W., Qin, Boqiang, Sohngen, Brent L., Stumpf, Richard P., Visser, Petra M., and Wilhelm, Steven W.
Abstract:: In early August 2014, the municipality of Toledo, OH (USA) issued a ‘do not drink’ advisory on their water supply directly affecting over 400,000 residential customers and hundreds of businesses (Wilson, 2014). This order was attributable to levels of microcystin, a potent liver toxin, which rose to 2.5 μg L⁻¹...

Planning for Change: Assessing the Potential Role of Marine Protected Areas and Fisheries Management Approaches for Resilience Management in a Changing Ocean

Creator:: Kroeker, Kristy J., Carr, Mark H., Raimondi, Peter T., Caselle, Jennifer E., Washburn, Libe, Palumbi, Stephen R., Barth, John A., Chan, Francis, Menge, Bruce A., Milligan, Kristen, Novak, Mark, and White, J. Wilson
Abstract:: Despite progressive policies and continued advances in ocean management, numerous shifts associated with global changes have been observed in marine ecosystems in recent years, including warming, ocean acidification, and deoxygenation. As global change accelerates, science is needed to inform evidence-based management strategies for continued ecosystem services. Resilience management, in which...

Diet variability of forage fishes in the Northern California Current System

Creator:: Hill, Andrew D., Daly, Elizabeth A., and Brodeur, Richard D.
Abstract:: As fisheries management shifts to an ecosystem-based approach, understanding energy pathways and trophic relationships in the Northern California Current (NCC) will become increasingly important for predictive modeling and understanding ecosystem response to changing ocean conditions. In the NCC, pelagic forage fishes are a critical link between seasonal and interannual variation...

Debris flow initiation in proglacial gullies on Mount Rainier, Washington

Creator:: Legg, Nicholas T., Meigs, Andrew J., Grant, Gordon E., and Kennard, Paul
Abstract:: Effects of climate change, retreating glaciers, and changing storm patterns on debris flow hazards concern managers in the Cascade Range (USA) and mountainous areas worldwide. During an intense rainstorm in November 2006, seven debris flows initiated from proglacial gullies of separate basins on the flanks of Mount Rainier. Gully heads...
