Moored observations of currents and temperatures made in the upper 600 m on
eddy-resolving scales over a 2-year period are used to examine the spatial and temporal
characteristics of the California Current mesoscale circulation. The observations were
made at three principal longitudes: 124°W, 126°W, and 128°W in the vicinity of...
Cloud radars at X, Ka and W-bands have been used in the past for ocean studies of clouds, but the lack of suitable stabilization has limited their usefulness in obtaining accurate measurements of the velocity structure of cloud particles and the heights of cloud features. A 94 GHz (W-band) radar...
We propose three sampling-based motion planning algorithms for generating informative mobile robot trajectories. The goal is to find a trajectory that maximizes an information quality metric (e.g. variance reduction, information gain, or mutual information) and also falls within a pre-specified budget constraint (e.g. fuel, energy, or time). Prior algorithms have...
The purpose of this study was to test two hypotheses. The first
hypothesis interprets allochthonous rocks in the Willow Creek area of the
Pinyon Range as lying on flat, superficial thrusts that truncate the
underlying folded Mississippian rocks of the Antler flysch sequence.
The second hypothesis interprets the allochthonous rocks...

Assessment of potential climate change impacts on stream water temperature (Tₛ) across large scales remains challenging for resource managers because energy exchange processes between the atmosphere and the stream environment are complex and uncertain, and few long-term datasets are available to evaluate changes over time. In this study, we demonstrate...
Fisheries management based on catch shares – divisions of annual fleet-wide quotas among individuals or groups – has been strongly supported for their economic benefits, but biological consequences have not been rigorously quantified. We used a global meta-analysis of 345 stocks to assess whether fisheries under catch shares were more...
Here we present a phylogeny of beetles (Insecta: Coleoptera) based on DNA sequence data from eight nuclear genes, including six single-copy nuclear protein-coding genes, for 367 species representing 172 of 183 extant families. Our results refine existing knowledge of relationships among major groups of beetles. Strepsiptera was confirmed as sister...
Toxicological studies show that oral doses of nickel can cause allergic contact dermatitis, and routes of exposure, such as nickel leached from stainless steel cookware are not well characterized. In this study, four variables: grade of stainless steel, cook time, stainless steel seasoning or cooking cycles, and commercial tomato sauces,...

Precision agriculture offers the technologies to manage for infield variability and incorporate variability into irrigation management decisions. The major limitation of this technology often lies in the reconciliation of disparate data sources and the generation of irrigation prescription maps. Here the authors explore the utility of the cosmic-ray neutron probe...
