Acoustic characterization of soniferous fishes of North Carolina estuaries
Pullinger, Robert Christopher. -
ASSESSMENT OF NICHE PARTITIONING IN CO-OCCURRING SILVERSIDES FROM THE ALBEMARLE AND PAMLICO SOUNDS OF NORTH CAROLINA
Cope, W. Robert (2015-05-01)The niche partitioning hypothesis predicts that two species cannot compete for the same limited resources and that one species should differentiate (genetically, morphologically or behaviorally), so that the two species ... -
Can Passive Acoustics be Used to Estimate the Length of Atlantic Croaker (Micropogonias undulatus) within the Pamlico Estuary?
Krahforst, Cecilia S. (East Carolina University, 2010)The Atlantic States Marine Fisheries Council (AFMFC) attributes the decline in the Atlantic croaker (Micropogonias undulatus) stock to over-fishing practices. The majority of collected Atlantic croaker are small, young of ... -
Characterization of critical spawning habitats of weakfish, spotted seatrout and red drum in Pamlico Sound using hydrophone surveys
Luczkovich, Joseph J.; Daniel, Hal J., III; Sprague, Mark W. (1999)Final report for "Characterization of critical spawning habitats of weakfish, spotted seatrout and red drum in Pamlico Sound using hydrophone surveys." -
Development of a Finite Difference Time Domain (FDTD) Model for Propagation of Transient Sounds in Very Shallow Water
Sprague, Mark W.; Luczkovich, Joseph J. (2013-08-12)We developed a finite difference time domain (FDTD) model for sound propagation using pressure and velocity grids with both three-dimensional Cartesian and two-dimensional cylindrical implementations. Propagation parameters, ... -
Effects of Land Use Change on Juvenile Fishes, Blue Crab, and Brown Shrimp Abundance in the Estuarine Nursery Habitats of North Carolina
Meyer, Gregory F. (East Carolina University, 2011)The U.S. coastal region is home to more than half of the American population. Also, the coastal counties' population is growing much faster than that of inland counties. With a high density and an increasing population, ... -
Impact of Vessel Noise on Oyster Toadfish (Opsanus tau) Behavior and Implications for Underwater Noise Management
Krahforst, Cecilia S. (East Carolina University, 2017-05-03)Underwater noise and its impacts on marine life are growing management concerns. This dissertation considers both the ecological and social concerns of underwater noise, using the oyster toadfish (Opsanus tau) as a model ... -
Linking Fishing Behavior and Ecosystem Dynamics Using Social and Ecological Network Models
Luczkovich, Joseph J.; Johnson, Jeffrey C.; Deehr, Rebecca A.; Hart, Kevin J.; Clough, Lisa M.; Griffith, David C. (2021) -
Listening to Ocean Life
Luczkovich, Joseph J.; Sprague, Mark; Rulifson, Roger (2019-05-30)By using a remotely controlled autonomous vehicle ("Blackbeard" the Acoustic Wave Glider), the authors made recordings of sounds produced by striped cusk eels, sea robins, oyster toadfish, weakfish, red drum, spotted ... -
Measuring the Ecosystem Impacts of Commercial Shrimp Trawling and Other Fishing Gear in Core Sound, North Carolina Using Ecological Network Analysis
Deehr, Rebecca A. (East Carolina University, 2012)The impacts of commercial trawling are well documented, especially alteration of benthic environments, removal of targeted and by-catch species, and alteration of food webs. I investigated and modeled the impacts of shrimp ... -
MONITORING FISH SPAWNING LOCATIONS AND MARINE MAMMAL SOUNDS WITH PASSIVE ACOUSTIC RECORDER ON A WAVE GLIDER
Luczkovich, Joseph J.; Sprague, Mark; Rulifson, Roger (2019-07-08)Remote observations of marine animal behavior have one distinct advantage over direct observations: the observer is not present to disturb the animals. There are no vessel noises, no diver’s bubbles, no people present that ... -
A MULTIVARIATE APPROACH TO ESTABLISH HABITAT CLASSIFICATIONS IN A CORAL REEF ECOSYSTEM USING LANDSAT 7 SATELLITE IMAGERY AT TURNEFFE A TOLL, BELIZE, CENTRAL AMERICA.
Rueter, Jason Walter (2004-03)The use of multivariate cluster and discriminant function analysis of ground truth data and LANDSAT 7 satellite imagery (23 May 2000) was examined to classify tropical marine habitats at Tumeffe Atoll, Belize. Ground ... -
Particle motion and sound propagation near boundaries
Sprague, Mark W.; DeVille, Phillip; Luczkovich, Joseph J. (2019-07-09)It has been well-established that the inner ears of fishes act as particle motion detectors (Popper and Hawkins, 2018) and that fishes use particle motion to determine the direction of a sound source (Hawkins and Popper, ... -
