Construction, Figures Of Merit And Testing Of A Single-Cell Fluorescence Excitation Spectroscopy System, Laura S. Hill, Tammi L. Richardson, Louisa T.M. Profeta, Timothy J. Shaw, Christopher J. Hintz, Benjamin S. Twining, Evelyn Lawrenz, Micheal L. Myrick

Faculty Publications

Characterization of phytoplankton community composition is critical to understanding the ecology and biogeochemistry of the oceans. One approach to taxonomic characterization takes advantage of differing pigmentation between algal taxa and thus differences in fluorescence excitation spectra. Analyses of bulk water samples, however, may be confounded by interference from chromophoric dissolved organic matter or suspended particulate matter. Here, we describe an instrument that uses a laser trap based on a Nikon TE2000-U microscope to position individual phytoplankton cells for confocal fluorescence excitation spectroscopy, thus avoiding interference from the surrounding medium. Quantitative measurements of optical power give data in the form of …

A Transition-Phase Teleconnection Of The Pacific Quasi-Decadal Oscillation, Shih-Yu (Simon) Wang, R. R. Gillies, L. E. Hipps, J. Jin

Plants, Soils, and Climate Faculty Publications

The atmospheric circulation patterns associated with the Pacific quasi-decadal oscillation (QDO) are investigated using available observational data from 1948 to 2007. Previous studies indicate that the Pacific QDO is characterized by a distinct lifecycle in the form of sea surface temperature (SST) patterns. In the warm and cool phases of the Pacific QDO, the SST patterns resemble those associated with the El Niño-Southern Oscillation (ENSO). During the warm–cool and cool–warm transitions of the Pacific QDO, recurrent SST patterns are also clearly visible. The rotated empirical orthogonal function analysis on the 10–15 year filtered data shows that the evolutions of SST …

Diurnal Movements And Site Fidelity Of The Florida Manatee, Trichechus Manatus Latirostris, In Fort Lauderdale, Fl., Kym Walsh

HCNSO Student Theses and Dissertations

The diurnal movements of Florida manatees (Trichechus manatus latirostris) in warmwater refugia are poorly understood and these may prove critical in accurately estimating populations of these animals. Previous studies indicate that manatee populations in such refuges in Tampa Bay, FL, peak mid-day and decline towards evening when the animals leave to forage. This trend suggests that variation in the timing of aerial manatee population surveys may hamper accurate estimation of the true population size. Aerial survey counts are known to underestimate population size, yet the extent of the underestimation may be greater than expected. In this study data …

Peconic Bays Estuary Benthic Gis Data, Robert M. Cerrato

SoMAS Research Data

Benthic habitat maps of the estuary seafloor can increase our knowledge of the range and variability in benthic habitats, assist managers in their efforts to protect and/or restore commercially and recreationally important finfish and shellfish, link land usage (e.g. developed vs. undeveloped areas) and water quality data to benthic habitat quality, and make it possible to utilize faunal data as a long-term indicator of the overall “health” of the estuary. This study combined high-resolution sonar surveys with physical and faunal characteristics at point locations in different seafloor areas of the Peconic Bays Estuary. Sonar mapping used multibeam swath bathymetry to …

Effects Of Drought On Avian Community Structure, Thomas P. Albright, Anna M. Pidgeon, Chadwick D. Rittenhouse, Murray K. Clayton, Curtis H. Flather, Patrick D. Culbert, Brian D. Wardlows, Volker C. Radeloff

National Drought Mitigation Center: Faculty Publications

Droughts are expected to become more frequent under global climate change. Avifauna depend on precipitation for hydration, cover, and food. While there are indications that avian communities respond negatively to drought, little is known about the response of birds with differing functional and behavioral traits, what time periods and indicators of drought are most relevant, or how response varies geographically at broad spatial scales. Our goals were thus to determine (1) how avian abundance and species richness are related to drought, (2) whether community variations are more related to vegetation vigor or precipitation deviations and at what time periods relationships …

Temperature Trends And Episodic Changes Of The Middle Atmosphere Over Logan Utah With Consideration To Model Specification, Troy A. Wynn, Vincent B. Wickwar

Reports

A summary of the linear trends estimated from the USU Rayleigh Lidar (41.74o N, 118oW) temperature data set. The data set covers a time span from September, 1993 to August, 2003 and an altitude range of 45 to 80 km. The data set includes 584 data points at 45 km to 580 data points at 80 km. Cooling trend profiles are calculated and compared to results from other researchers. Collinearity and bias are also considered as issues that could affect the regression results. Also considered is the possibility that the Mt. Pinatubo eruption has influenced temperature trend estimates. This is …

A Passive Sampler For Ambient Gaseous Oxidized Mercury Concentrations, Seth N. Lyman, Mae Sexauer Gustin, Eric M. Prestbo

USU Uintah Basin Faculty Publications

This paper reports on the development of a passive sampler for estimating gaseous oxidized mercury concentrations. Atmospheric gaseous oxidized mercury concentrations calculated from passive sampler data were correlated with those obtained using an automated analyzer (r2 = 0.71, p < 0.01, n = 110 for one-week deployments; r2 = 0.89, p < 0.01, n = 22 for two-week deployments). Sampler uptake was not significantly affected by changes in temperature, humidity, or ozone concentration, but it was slightly dependent on wind speed. As such, an equation for correcting data due to this factor was developed based on wind tunnel and field data. The detection limit for a two-week sampler deployment was ∼5 pg m−3. Field data collected in Nevada and the southeastern United States showed these samplers are useful for investigating spatial and temporal variability in gaseous oxidized mercury concentrations.

Geochemical And Mineralogical Evidence For Sahara And Sahel Dust Additions To Quaternary Soils On Lanzarote, Eastern Canary Islands, Spain, Daniel R. Muhs, James Budahn, Gary Skipp, Joseph M. Prospero, Deanna Patterson, E. Arthur Bettis Iii

United States Geological Survey: Staff Publications

Africa is the most important source of dust in the world today, and dust storms are frequent on the nearby Canary Islands. Previous workers have inferred that the Sahara is the most important source of dust to Canary Islands soils, with little contribution from the Sahel region. Soils overlying a late Quaternary basalt flow on Lanzarote, Canary Islands, contain, in addition to volcanic minerals, quartz and mica, exotic to the island!s bedrock. Kaolinite in the soils also likely has an exotic origin. Trace-element geochemistry shows that the soils are derived from varying proportions of locally derived basalt and African dust. …

The Influence Of Nutrients And Physical Habitat In Regulating Algal Biomass In Agricultural Streams, Mark D. Munn, Jeffrey Frey, Anthony Tesoriero

United States Geological Survey: Water Reports and Publications

This study examined the relative influence of nutrients (nitrogen and phosphorus) and habitat on algal biomass in five agricultural regions of the United States. Sites were selected to capture a range of nutrient conditions, with 136 sites distributed over five study areas. Samples were collected in either 2003 or 2004, and analyzed for nutrients (nitrogen and phosphorous) and algal biomass (chlorophyll a). Chlorophyll a was measured in three types of samples, fine-grained benthic material (CHLFG), coarse-grained stable substrate as in rock or wood (CHLCG), and water column (CHLS). Stream and riparian habitat were characterized at each site. TP ranged from …

Development And Application Of A Pollen-Based Paleohydrologic Reconstruction From The Lower Roanoke River Basin, North Carolina, Usa, Debra Willard, Christopher Bernhardt, Roger Brown, Bryan Landacre, Philip A. Townsend

United States Geological Survey: Staff Publications

We used pollen assemblages to reconstruct late-Holocene paleohydrologic patterns in floodplain deposits from the lower Roanoke River basin (North Carolina, southeastern USA). Using 120 surface samples from 38 transects, we documented statistical relationships between pollen assemblages, vegetation, and landforms. Backswamp pollen assemblages (long hydroperiods) are dominated by Nyssa (tupelo) and Taxodium (cypress) and have high pollen concentrations. Sediments from elevated levees and seasonally flooded forests (shorter hydroperiods) are characterized by dominant Pinus (pine) pollen, variable abundance of hardwood taxa, and low pollen concentrations. We apply the calibration data set to interpret past vegetation and paleohydrology. Pollen from a radiocarbon-dated sediment …

Multimedia And Ultrafiltration For Reverse Osmosis Pretreatment Aboard Naval Vessels, Angela C. Mehner

Inquiry: The University of Arkansas Undergraduate Research Journal

The US Navy is interested in improving the pretreatment for shipboard Reverse Osmosis potable water systems. To investigate this problem, the Navy prepared a Task for the 2010 WERC (http://www.werc.net) competition. The research described in this paper was performed to compete in this WERC Task and ultimately received a 1st place award. Several technologies were considered as options for improving the current pretreatment process. Multi-media filtration followed by ultrafiltration was chosen as the most economical solution. This paper presents the final design for a full-scale shipboard system that incorporates multimedia filtration and ultrafiltration yet requires minimal space and optimal power …

2010 Tropical Coral Reefs (Appendix 10), Joana Figueiredo

Marine & Environmental Sciences Faculty Reports

SUMMARY

• Coral reef ecosystems are global biodiversity hotspots that depend on the massive calcium carbonate structures mainly deposited by scleractinian (i.e., “hard”) corals. Scleractinian coral distribution is primarily limited by sea-surface temperature, light, depth, ocean pH, sea water salinity, nutrients and sediment loads. These ecosystems are currently threatened by localized stresses such as overfishing and destructive fishing practices, pollution, terrestrial nutrient and sediment run-off, but are increasing impacted by direct and indirect impacts of rising CO2 concentrations and climate change.
• Coral reefs provide a broad range of ecosystems services with high socio-economic value: tourism, fisheries (food and employment), nutrient cycling, …

Sailfish (Istiophorus Platypterus) Habitat Utilization In The Southern Gulf Of Mexico And Florida Straits With Implications On Vulnerability To Shallow-Set Pelagic Longline Gear, David W. Kerstetter, Shannon Michael Bayse, John E. Graves

Marine & Environmental Sciences Faculty Reports

A total of 19 pop-up satellite archival tags (PSATs) were deployed on sailfish in the southern Gulf of Mexico between 2005 and 2007 aboard a commercial pelagic longline vessel (n = 18) and a recreational rod-and-reel vessel (n = 1). All PSATs were programmed to collect pressure (depth), temperature, and light-level data for 10 days at approximately 90-second intervals. These point-level data were not summarized prior to transmission, allowing the reconstruction of vertical movement patterns. Three tags suggested mortality events and were excluded from subsequent analyses. We present the preliminary data analyses from the remaining 16 PSATs. Sailfish are primarily …

Standardized Catch Rates Of Sandbar Sharks And Dusky Sharks In The Vims Longline Survey: 1975-2009, Jason G. Romine, Kristene T. Parsons, R. Dean Grubbs, John A. Musick, Tracey Sutton

Marine & Environmental Sciences Faculty Reports

The Virginia Institute of Marine Science has conducted a fishery-independent longline survey during summer months since 1974. Data for sandbar sharks and dusky sharks captured in the survey between 1975 and 2009 are presented. Most of the sandbar sharks encountered by the survey were immature, with females composing almost all of the mature sandbar catch. Almost all dusky sharks captured were immature. Most of the catch since the early 1990’s has been composed of 0-4 year age classes. Nominal and standardized catch rates are presented. CPUE for both species decreased from the early 1980’s to minima in 1992. CPUE then …

Seasonal And Salinity Effects On The Distribution Of Higher Filamentous Marine Fungi At Rookery Bay, Fl., Julia Ossler

HCNSO Student Theses and Dissertations

More than 500 species of higher marine fungi in over 300 genera have been described. Many marine fungi are highly specialized for marine environments relative to their terrestrial counterparts, having appendaged ascospores and conidia to aid in buoyancy, entrapment, and adherence to substrates. They have been reported to inhabit a wide variety of substrates including decaying wood, leaves, calcareous and chitinous substrates, seaweeds, and seagrasses. Most early studies on marine fungi were carried out in temperate regions. Investigations have now shifted to tropical locations in order to better evaluate the abundance and diversity of marine fungi on a global basis. …

Climate Change And Freshwater Resources In Oregon, Heejun Chang, Julie Jones

Institute for Sustainable Solutions Publications and Presentations

Climate change will affect various sectors of water resources in Oregon in the 21st century. The observed trends in streamflow show significant declines in September flow and, although not significant, increases in March flow in many transient rain-snow basins. These streamflow trends are associated with rising temperature and coincident declines in snowpack in spring in the latter half of the 20th century. While there are no distinct trends in high precipitation events, such events are associated with climate variability such as ENSO and PDO. Effects of ENSO and PDO are more pronounced at the beginning and end of the wet …

Paleo-Environmental Changes In The Uvs Nuur Basin (Northwest-Mongolia), Michael Walther

Erforschung biologischer Ressourcen der Mongolei / Exploration into the Biological Resources of Mongolia, ISSN 0440-1298

Geomorphological, geochemical, sedimentological and palynological results are presented against the background of palaeoclimatic changes during the past 15,000 years, yielding a chrono-, bio- and morphostratigraphical model of landscape evolution in the region of northern Central Asia. Holocene and Late-Glacial climatic fluctuations there are shown to correlate well with conditions in central Europe. Particular attention is given to the importance of the palaeoclimatic interpretation of lake Basin sediments when reconstructing the palaeoenvironment.
