The Educational Training Of Storm Chasers And Storm Spotters In Relation To Geographical Dispersion Across The United States, Paul R. Zunkel
All Graduate Theses, Dissertations, and Other Capstone Projects
When severe weather strikes, storm chasers and storm spotters confirm that what forecasters and meteorologists are seeing on a radar screen is actually occurring in the field. While some documenters are classically trained (i.e. they have a background in atmospheric science and or meteorology attained from a 4 year university) many others are not. There are currently two organizations available for the weather enthusiast to be a part of, SKYWARN and SpotterNetwork. These organizations give weather enthusiasts a background knowledge into severe weather; however, many weather enthusiasts are not classically trained and most have not taken any formal education in …

—Rockfishes (Sebastes spp.) tend to aggregate near rocky, cobble, or generally rugged areas that are difficult to survey with bottom trawls, and evidence indicates that assemblages of rockfish species may differ between areas accessible to trawling and those areas that are not. Consequently, it is important to determine grounds that are trawlable or untrawlable so that the areas where trawl survey results should be applied are accurately identified. To this end, we used multibeam echosounder data to generate metrics that describe the seafloor: backscatter strength at normal and oblique incidence angles, the variation of the angle-dependent backscatter strength within 10° …
A Procedure For Developing An Acceptance Test For Airborne Bathymetric Lidar Data Application To Noaa Charts In Shallow Waters, Gretchen Imahori, Jeffrey Ferguson, Toshi Wozumi, Dave Scharff, Shachak Pe'eri, Christopher Parrish, Stephen A. White, Inseong Jeong, Jon Sellars, Michael Aslaksen
Center for Coastal and Ocean Mapping
National Oceanic and Atmospheric Administration (NOAA) hydrographic data is typically acquired using sonar systems, with a small percent acquired via airborne lidar bathymetry for near‐shore areas. This study investigated an integrated approach for meeting NOAA’s hydrographic survey requirements for near‐shore areas of NOAA charts, using the existing topographic‐bathymetric lidar data from USACE’s National Coastal Mapping Program (NCMP). Because these existing NCMP bathymetric lidar datasets were not collected to NOAA hydrographic surveying standards, it is unclear if, and under what circumstances, they might aid in meeting certain hydrographic surveying requirements. The NCMP’s bathymetric lidar data are evaluated through a comparison to …

Vibrio Parahaemolyticus Interactions With Chitin In Response To Environmental Factors, Vanessa Molina
LSU Doctoral Dissertations
Vibrio parahaemolyticus is a naturally occurring chitinoclastic human pathogen that adsorbs to substrates, including chitinous copepods and oysters, as part of its ecology, a phenomenon that is important in its responses to changes in environmental factors such as temperature and salinity. Little is known about acute responses of V. parahaemolyticus when subjected to abrupt environmental changes such as those encountered during postharvest oyster treatments such as icing, exposure to mammalian host conditions, and transport via ballast water. The following in vitro studies investigated V. parahaemolyticus adsorption and gene expression as a function of substrate, temperature, and salinity as a model …

Geography
[1] Our understanding of past sea-ice variability is limited by the short length of satellite and instrumental records. Proxy records can extend these observations but require further development and validation. We compare methanesulfonic acid (MSA) and chloride (Cl-) concentrations from a new firn core from coastal West Antarctica with satellite-derived observations of regional sea-ice concentration (SIC) in the Amundsen Sea (AS) to evaluate spatial and temporal correlations from 2002-2010. The high accumulation rate (∼39 g·cm-2·yr-1) provides monthly resolved records of MSA and Cl-, allowing detailed investigation of how regional SIC is recorded in the ice-sheet stratigraphy. Over the period 2002-2010 …

Optech, Inc. in a partnership with the University of Southern Mississippi (USM) has developed a new shallow water bathymetic LIDAR and imaging system known as the Coastal Zone Imaging and Mapping LIDAR (CZMIL). This system tightly integrates a digital camera and hyperspectral imager with a new combined bathymetric and topographic LIDAR, into a single platform designed to map all features of the coastal zone, including the water surface, water column, seabed (depth and makeup), and land (height and makeup). The LIDAR component is a completely new design that enables the green laser to collect height/depth data on both land and …

Uncertainty Evaluation Of The Edge Tech 4600 Swath Bathymetry System, David Dodd
Hydrographic Science Research Center
For shallow water surveys, accuracies achievable from phase differencing swath bathymetry systems are approaching those of multi-beam systems. Advantages of phase differencing systems include wider coverage, which increases efficiency, and simultaneous depth/side scan sonar imagery, making them ideal for very shallow water surveys. Before these systems can gain wider acceptance in the hydrographic surveying community, rigorous accuracy analysis must be performed and reasonable uncertainty models developed. The University of Southern Mississippi’s Hydrographic Science Research Center conducted an evaluation of their EdgeTech 4600™ 540 kHz phase differencing system in comparison with their Reson Seabat 7125™ beam forming system. The survey was …

Contribution Of The Pacific Decadal Oscillation To Global Mean Sea Level Trends, B. D. Hamlington, R. R. Leben, M. W. Strassburg, R. S. Nerem, K-Y. Kim
CCPO Publications
Understanding and explaining the trend in global mean sea level (GMSL) have important implications for future projections of sea level rise. While measurements from satellite altimetry have provided accurate estimates of GMSL, the modern altimetry record has only now reached 20 years in length, making it difficult to assess the contribution of decadal to multidecadal climate signals to the global trend. Here, we use a sea level reconstruction to study the 20 year trends in sea level since 1950. In particular, we show that the Pacific Decadal Oscillation (PDO) contributes significantly to the 20 year trends in GMSL. We estimate …

Extracting Tidal Variability Of Sea Ice Concentration From Amsr-E Passive Microwave Single-Swath Data: A Case Study Of The Ross Sea, Stefanie Mack, Laurie Padman, John M. Klinck
CCPO Publications
The periodic divergence of stress applied by ocean tidal currents to sea ice affects the time-averaged ice concentration (Cice) and heat and freshwater fluxes at the ocean surface. We demonstrate that, at sufficiently high latitudes, tidal variability in Cice can be extracted from single-swath data from the Advanced Microwave Scanning Radiometer–EOS (AMSR-E) satellite passive microwave sensor, although time intervals between swaths are irregular. For the northwest Ross Sea where tidal currents are large, tidal divergence is the dominant cause of Cice variability in winter, with a range of ±0.2 about a mean of ~0.8. Daily-averaged C …

On The Role Of Coastal Troughs In The Circulation Of Warm Circumpolar Deep Water On Antarctic Shelves, Pierre St-Laurent, John M. Klinck, Michael S. Dinniman
CCPO Publications
Oceanic exchanges across the continental shelves of Antarctica play an important role in biological systems and the mass balance of ice sheets. The focus of this study is on the mechanisms responsible for the circulation of warm Circumpolar Deep Water (CDW) within troughs running perpendicular to the continental shelf. This is examined using process-oriented numerical experiments with an eddy-resolving (1 km) 3D ocean model that includes a static and thermodynamically active ice shelf. Three mechanisms that create a significant onshore flow within the trough are identified: 1) a deep onshore flow driven by the melt of the ice shelf, 2) …

Intrusion Of Warm Surface Water Beneath The Mcmurdo Ice Shelf, Antarctica, A. A. Stern, M. S. Dinniman, V. Zagorodnov, S. W. Tyler, D. M. Holland
CCPO Publications
A 6 month temperature record collected below McMurdo Ice Shelf in 2011-2012 shows the temporal and spatial structure of the summertime warm water signal that penetrates beneath the ice shelf. The strength and duration of the warm water intrusion suggest an annual melt rate at Windless Bight of 0.71 m/yr. A Ross Sea numerical model demonstrates a seasonal warm water pathway leading from the west side of the Ross Sea Polynya (RSP) toward McMurdo Sound. The warm water enters McMurdo Sound, subducts beneath the ice shelf and causes accelerated summer melting. Temperature data were recorded using Distributed Temperature Sensing fiber …
