Edge gradients provide evidence of ecological interactions in planktonic thin layers

Creator:: Benoit-Bird, Kelly J., Cowles, Timothy J., and Wingard, Christopher E.
Abstract:: Physical, optical, and acoustical data from Monterey Bay, California, USA, describing the distributions of phytoplankton, zooplankton, and small fish as well as gradients in the physical habitat were used to examine the interactions between vertically compressed plankton structures (thin layers), their consumers, and the local physical forces they experience. The...

Unique Structural Properties and Motifs of Metal-Oxides from Solids to Clusters

Creator:: Malmberg, Christopher E.
Abstract:: In this dissertation, the structural properties, thermodynamics and defect behavior of amorphous metal oxides and polyoxometalates are studied. Amorphous metal oxides have many applications, most notably as a semiconducting material used as the active matrix of thin film transistors. Alas, the amorphous nature of these materials makes studying them rather...

Watershed restoration, jobs-in-the-woods, and community assistance : Redwood National Park and the Northwest Forest Plan

Creator:: DeForest, Christopher E.
Abstract:: There are many parallels between the 1978 legislation to expand Redwood National Park and the Northwest Forest Plan, which together with the Northwest Economic Adjustment Initiative formed the 1993 Pacific Northwest Initiative. In both situations, the Federal Government sought to promote retraining for displaced workers, to undertake watershed assessment and...

Development of an autonomous in-situ instrument for long-term monitoring of Cu(II) in the marine environment

Creator:: Holm, Christopher E.
Abstract:: An autonomous, in-situ instrument was developed to detect dissolved copper in seawater, suitable for deployment on time scales from weeks to months. A commercially available in-situ nitrate analyzer (YSI 9600) was adapted to measure copper (II) in seawater by chemiluminescence. Modifications included construction of a photomultiplier (PMT) based detector and...

ICESat-2 Bathymetric Log10 Tomogram Data

Creator:: Corcoran, Forrest and Parrish, Christopher E.
Abstract:: Bathymetry data (measurements of the elevations of submerged surfaces like the seafloor and lake beds) are an important factor in many scientific, economic, and engineering disciplines. Bathymetric surveys are widely used for benthic habitat mapping, flood inundation modeling, marine resource delineation, and nautical charting. While this ubiquity makes the generation...

Quantifying predator dependence in the functional response of generalist predators

Creator:: Novak, Mark, Wolf, Christopher, Coblentz, Kyle E., and Shepard, Isaac D.
Abstract:: A long-standing debate concerns how functional responses are best described. Theory suggests that ratio dependence is consistent with many food web patterns left unexplained by the simplest prey-dependent models. However, for logistical reasons, ratio dependence and predator dependence more generally have seen infrequent empirical evaluation and then only so in...

Validity and Value of Wave Energy Generation as Blackout Risk Mitigation for the Central Oregon Coast

Creator:: Burright, Jeffrey, Clark, Caitlyn E., Johnson, Brandon, and Sharp, Christopher
Abstract:: Energy security is a vital but often unmet requirement for community resiliency. Electricity availability is essential to the functioning of the economy, individual households, and the collective essential services that provide health, safety, and the basic human needs to sustain life. Coastal communities in Oregon face special vulnerability because they...

Influential disease foci in epidemics and underlying mechanisms: a field experiment and simulations

Creator:: Estep, Laura K., Sackett, Kathryn E., and Mundt, Christopher C.
Abstract:: Pathogen invasions pose a growing threat to ecosystem stability and public health. Guidelines for the timing and spatial extent of control measures for pathogen invasions are currently limited, however. We conducted a field experiment using wheat (Triticum aestivum) stripe rust, caused by the wind-dispersed fungus Puccinia striiformis, to study the...

Carbon concentration of standing and downed woody detritus: Effects of tree taxa, decay class, position, and tissue type

Creator:: Harmon, Mark E., Fasth, Becky, Woodall, Christopher W., and Sexton, Jay
Abstract:: The degree to which carbon concentration (CC) of woody detritus varies by tree taxa, stage of decay, tissue type (i.e., bark versus wood), and vertical orientation was examined in samples of 60 tree species from the Northern Hemisphere. The mean CC of 257 study samples was 49.3% with a range...

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...
