Examining Industry Expectations for Content Knowledge in Mechatronics Across Career and Professional Certificate Programs

Creator:: Raghunath, Nisha, Haapala, Karl R., and Sanchez, Christopher A.
Abstract:: Technological advancements, ever-evolving necessary skillsets, and an aging workforce have all contributed to a growing labor crisis wherein there are not enough qualified candidates available to fill vacant jobs in the manufacturing sector – in essence, a skilled labor shortage. Certificate programs (earned independently in a two-year college, while working...

Eclipse Ice Core Accumulation and Stable Isotope Variability as an Indicator of North Pacific Climate

Creator:: Kelsey, Eric P., Wake, Cameron P., Yalcin, Kaplan, and Kreutz, Karl
Abstract:: The high accumulation rate and negligible amount of melt at Eclipse Icefield (3017 m) in the Saint Elias Range of Yukon, Canada, allows for the preservation of a high-resolution isotopic and glaciochemical records valuable for reconstruction of climatic variables. Each of the three Eclipse ice cores have a well-constrained depth–age...

An economic and environmental assessment model for microchannel device manufacturing: part 1-Methodology

Creator:: Gao, Qi, Lizarazo-Adarme, Jair, Paul, Brian K., and Haapala, Karl R.
Abstract:: To manage the effects of manufacturing industries on the economy and environment, design tools are needed that will aid engineers to assess manufacturing costs and environmental impacts early in design. The development of cost analyses and environmental assessments can be burdensome, but much of the data used in these analyses...

Changing concentrations of CO, CH₄, C₅H₈, CH₃Br, CH₃I, and dimethyl sulfide during the Southern Ocean Iron Enrichment Experiments

Creator:: Wingenter, Oliver W., Haase, Karl B., Strutton, Peter, Friederich, Gernot, Meinardi, Simone, Blake, Donald R., and Rowland, F. Sherwood
Abstract:: Oceanic iron (Fe) fertilization experiments have advanced the understanding of how Fe regulates biological productivity and air–sea carbon dioxide (CO₂) exchange. However, little is known about the production and consumption of halocarbons and other gases as a result of Fe addition. Besides metabolizing inorganic carbon, marine microorganisms produce and consume...

Experimental assessment of diazotroph responses to elevated seawater pCO₂ in the North Pacific Subtropical Gyre

Creator:: Böttjer, Daniela, Karl, David M., Letelier, Ricardo M., Viviani, Donn A., and Church, Matthew J.
Abstract:: We examined short-term (24–72 h) responses of naturally occurringmarine N2 fixing microorganisms (termed diazotrophs) to abrupt increases in the partial pressure of carbon dioxide (pCO2) in seawater during nine incubation experiments conducted between May 2010 and September 2012 at Station ALOHA (A Long-term Oligotrophic Habitat Assessment) (22°45′N, 158°W) in the...

The effect of zinc limitation on the transcriptome of Pseudomonas protegens Pf-5

Creator:: Lim, Chee Kent, Hassan, Karl A., Penesyan, Anahit, Loper, Joyce E., and Paulsen, Ian T.
Abstract:: Zinc is an important nutrient but can be lacking in some soil environments, influencing the physiology of soil-dwelling bacteria. Hence, we studied the global effect of zinc limitation on the transcriptome of the rhizosphere biocontrol strain Pseudomonas protegens Pf-5 (formerly Pseudomonas fluorescens). We observed that the expression of the putative...

Role of late winter mesoscale events in the biogeochemical variability of the upper water column of the North Pacific Subtropical Gyre

Creator:: Letelier, Ricardo M., Karl, David M., Abbott, Mark R., Flament, P., Freilich, Michael H., Lukas, Roger, and Strub, P. Ted
Abstract:: Continuous records of upper water column (0–150 m) temperature profiles, spectral distribution of downwelling irradiance, and phytoplankton solar-induced fluorescence at 25 m depth were obtained during the inaugural deployment of the Hawaii Air-sea Logging Experiment, A Long-term Oligotrophic Habitat Assessment (HALE ALOHA) mooring, near the Hawaii Ocean Time-series (HOT) Station...

Particle distributions and dynamics in the euphotic zone of the North Pacific Subtropical Gyre

Creator:: Barone, Benedetto, Bidigare, Robert R., Church, Matthew J., Karl, David M., Letelier, Ricardo M., and White, Angelicque E.
Abstract:: During the summer of 2012, we used laser diffractometry to investigate the temporal and vertical variability of the particle size spectrum (1.25–100 µm in equivalent diameter) in the euphotic zone of the North Pacific Subtropical Gyre. Particles measured with this optical method accounted for ∼40% of the particulate carbon stocks...

Phenology of particle size distributions and primary productivity in the North Pacific subtropical gyre (Station ALOHA)

Creator:: White, Angelicque E., Letelier, Ricardo M., Whitmire, Amanda L., Barone, Benedetto, Bidigare, Robert R., Church, Matthew J., and Karl, David M.
Abstract:: The particle size distribution (PSD) is a critical aspect of the oceanic ecosystem. Local variability in the PSD can be indicative of shifts in microbial community structure and reveal patterns in cell growth and loss. The PSD also plays a central role in particle export by influencing settling speed. Satellite-based...
