An analysis is presented for both ground- and satellite-based retrievals of total column ozone and nitrogen dioxide levels from the Washington, D.C., and Baltimore, Maryland, metropolitan area during the NASA-sponsored July 2011 campaign of Deriving Information on Surface COnditions from Column and VERtically Resolved Observations Relevant to Air Quality (DISCOVER-AQ). Satellite retrievals of total column ozone and nitrogen dioxide from the Ozone Monitoring Instrument (OMI) on the Aura satellite are used, while Pandora spectrometers provide total column ozone and nitrogen dioxide amounts from the ground. We found that OMI and Pandora agree well (residuals within ±25 % for nitrogen dioxide, …

Faculty Publications
We address the design, development, and testing of a pointer/tracker as a probe beam for the purpose of making high-speed, aero-optical measurements of the flow over a scaled beam director turret. The tracker uses retro-reflection of the probe beam off of a Reflexite annulus surrounding the turret. The constraints of the design required a near-total-commercial off the shelf system that could be quickly installed and removed in a rented aircraft. Baseline measurements of environmental vibrations are used to predict pointing performance; mitigation of line-of-sight jitter on the probe beam is achieved through passive isolation and the design of relay optics. …

The Production Of Organic Nitrates In Portland Oregon And The Columbia River Gorge, Holly Ann Neill
Dissertations and Theses
This work studied the production of aerosol-phase organic nitrates in both Portland and the Columbia River Gorge (CRG). Ozone and NOx species were investigated for correlation with organic nitrate aerosol, as they function as precursors to the production of organic nitrates. These ambient gas-phase measurements were collected in the same locations as high-volume (Hi-Vol) filters samples, in an urban and rural gorge setting to investigate correlations at the origin of the pollution plume and downwind. A novel Soxhlet extraction method for Hi-Vol filters was developed based on literature and EPA standard methods. Analysis for nitrate production was done by …

Ionospheric Induced Scintillation: A Space Weather Enigma, Jan Josef Sojka
All Physics Faculty Publications
The effect of scintillation on radio signals whose propagation path involves the Earth’s ionosphere is analogous to the allies of World War II receiving radio messages that had passed through the Enigma machine. In both these cases, man-made information has been encrypted and transmitted via radio. The two encryption methods are shown in Figure 1. The right panel shows a World War II Enigma machine used extensively by German U-boats to convey encrypted messages transmitted by radio [Perera, 2010]. The left panel gives an extreme example of a mapping of ionospheric irregularities at 3 m, which creates very severe scintillation …

3-D Modeling Of Coastal Aquifers, Seth Mullendore
Thinking Matters Symposium Archive
The purpose of this project is to assess the accuracy of a simplified computer modeling approach to coastal fresh/salt water interface groundwater flow. A number of test cases will be run to compare the results of the sophisticated USGS computer program SEAWAT with those of the program AnAqSim (analytic aquifer simulator), written by Dr. Charles Fitts. In order to reduce input complexity and model processing time, AnAqSim uses several simplifying assumptions. The analysis will lead to guidance regarding the range of conditions where the simplified approach is applicable, and the nature of the errors that may be introduced.

Underwater Radiated Noise Levels Of A Research Icebreaker In The Central Arctic Ocean, Ethan H. Roth, Val E. Schmidt, John A. Hildebrand, Sean M. Wiggins
Center for Coastal and Ocean Mapping
U.S. Coast Guard Cutter Healy's underwater radiated noise signature was characterized in the central Arctic Ocean during different types of ice-breaking operations. Propulsion modes included transit in variable ice cover, breaking heavy ice with backing-and-ramming maneuvers, and dynamic positioning with the bow thruster in operation. Compared to open-water transit, Healy's noise signature increased approximately 10 dB between 20 Hz and 2 kHz when breaking ice. The highest noise levels resulted while the ship was engaged in backing-and-ramming maneuvers, owing to cavitation when operating the propellers astern or in opposing directions. In frequency bands centered near 10, 50, and 100 Hz, …

Microhabitat Selection By Marine Mesoconsumers In A Thermally Heterogeneous Habitat: Behavioral Thermoregulation Or Avoiding Predation Risk?, Jeremy Vaudo, Michael Heithaus
Marine & Environmental Sciences Faculty Articles
Habitat selection decisions by consumers has the potential to shape ecosystems. Understanding the factors that influence habitat selection is therefore critical to understanding ecosystem function. This is especially true of mesoconsumers because they provide the link between upper and lower tropic levels. We examined the factors influencing microhabitat selection of marine mesoconsumers – juvenile giant shovelnose rays (Glaucostegus typus), reticulate whiprays (Himantura uarnak), and pink whiprays (H. fai) – in a coastal ecosystem with intact predator and prey populations and marked spatial and temporal thermal heterogeneity. Using a combination of belt transects and data …

Florida Keys Population Abundance Estimates For Nine Coral Species Proposed For Listing Under The U.S. Endangered Species Act, Steven Miller, William F. Precht, Leanne M. Rutten, Mark Chiappone
Marine & Environmental Sciences Faculty Reports
This report presents abundance and size-class distribution estimates for nine coral species in the Florida Keys and Dry Tortugas, all of which are proposed for listing or reclassification under the U.S. Endangered Species Act (ESA). The lack of population data for these species was highlighted as a deficiency in the ESA Review Process by the Biological Review Team (BRT) in their Status Review (Brainard et al. 2011) and also by the National Oceanic and Atmospheric Administration (NOAA) (Federal Register 2012). Field sampling protocols were adapted from Aronson et al. (1994) and the Atlantic and Gulf Rapid Reef Assessment program (Kramer …

Coral Population Trajectories, Increased Disturbance And Management Intervention: A Sensitivity Analysis, Bernhard Riegl, M. L. Berumen, Andrew Bruckner
Marine & Environmental Sciences Faculty Articles
Coral reefs distant from human population were sampled in the Red Sea and one-third showed degradation by predator outbreaks (crown-of-thorns-starfish = COTS observed in all regions in all years) or bleaching (1998, 2010). Models were built to assess future trajectories. They assumed variable coral types (slow/fast growing), disturbance frequencies (5,10,20 years), mortality (equal or not), and connectivity (un/connected to un/disturbed community). Known disturbances were used to parameterize models. Present and future disturbances were estimated from remote-sensing chlorophyll and temperature data. Simulations and sensitivity analysis suggest community resilience at >20-year disturbance frequency, but degradation at higher frequency. Trajectories move from fast-grower …

Changes In A Tropical Seagrass Environment After Installation Of Small Artificial Reefs, Joseph M. Penta
HCNSO Student Theses and Dissertations
The 3-dimensional structural complexity of coral reef environments is positively correlated with measurements of biodiversity and biomass. EcoReefs are a type of artificial reef that resemble branching corals, such as Acropora cervicornis, which provide an environment of high structural diversity, and that are effective at recruiting and sustaining fish populations. Little is known, however, about the effects of EcoReefs on the surrounding environments in which they are deployed, so this study examined the results after installing Ecoreef modules in a seagrass environment. The installation occurred in March 2009 at Coco Cay in the Berry Island chain in the Bahamas …
