Lighting A Path To Biofouling Prevention: Investigating The Effect Of Ultraviolet Light On Biofouling, Cierra Rose Braga
Lighting A Path To Biofouling Prevention: Investigating The Effect Of Ultraviolet Light On Biofouling, Cierra Rose Braga
Theses and Dissertations
Ultraviolet light (UV) is considered an environmentally friendly antifouling method because it disrupts biological growth without the release of harmful toxins. The application of UV for the marine shipping industry is a relatively new concept, and there still remains many unknowns before it can be fully implemented. This research investigated several aspects of applying UVC for the control of fouling. A novel method of using embedded UV LEDs within a silicone coating for fouling control proved to be very effective at preventing fouling. The research also investigated the effect of using an external UVC light treatment to control fouling on …
Wind-Driven Setup, Roughness, And Drag Over A Depth- And Fetch-Limited Coastal Estuary, Jeffrey Allen Colvin
Wind-Driven Setup, Roughness, And Drag Over A Depth- And Fetch-Limited Coastal Estuary, Jeffrey Allen Colvin
Theses and Dissertations
The understanding of the momentum exchange across the air-sea interface is critical to accurately model and forecast wind speed, wave properties, setup, and circulation. This is particularly true for a restricted estuary, such as the Indian River Lagoon (IRL), where wind is the driving force behind water movement due to the limited number of direct ocean connections. Current atmospheric and hydrodynamic models use formulations of the drag coefficient and/or roughness length based on open ocean studies in which wave properties are not considered. This dissertation develops two parameterizations – one for wind setup and one for the drag coefficient – …
Morphologic Evolution Of A Nearshore Berm: One Year Monitoring At Ft. Myers Beach, Florida, Kristopher Jason Enfinger
Morphologic Evolution Of A Nearshore Berm: One Year Monitoring At Ft. Myers Beach, Florida, Kristopher Jason Enfinger
Theses and Dissertations
Nourishment in the form of a nearhsore berm has become an important alternative method to protecting shorelines and introducing sediment back into the littoral system. In 2009, a nearshore berm was constructed at Ft. Myers Beach, Florida by the U.S. Army Corps of Engineers through maintenance dredging of a nearby navigational channel at Matanzas Pass. Constructed in the form of a nearshore bar, the berm was one of the shallowest placements in a low-wave energy setting. The Coastal Research Lab at the University of South Florida (USF-CRL) conducted field monitoring for the first four years after the construction. This project …
