For the marine industry biofouling has a negative reputation. On ship hulls, the accumulation of these unwanted plants and animals can lead to increased drag, fuel consumption, and greenhouse gas emissions. Offshore platforms are also subject to biofouling which can result in corrosion and hydrodynamic loading, thus shortening their lifespan. While the harmful impacts of biofouling are commonly reported throughout the literature, biofouling can also benefit both aquatic and human populations. Common biofouling organisms act as natural filtration systems, thus improving water quality. Many of the same flora and fauna serve as a food source, and structures could be designed …
Investigation On The Effects Of Biofouling On The Boundary Layer, Adam N. Bacon
Investigation On The Effects Of Biofouling On The Boundary Layer, Adam N. Bacon
University of New Orleans Theses and Dissertations
This study is an investigation of the effect of biofouling on the boundary layer of a flat plate and a NACA 4-digit series foil. Three identical hydrofoils made of resin were placed in the Gulf of Mexico at Grand Isle, Louisiana, and observed and analyzed by marine biologists at the University of New Orleans for their species composition. The resulting biofouling that grew was primarily made up of barnacles and bryozoans. The foils were submerged in an open channel flume at zero incidence and subjected to a series of experiments whose arc-length Reynolds numbers ranged from approximately 13000 to 32000. …
The Relationship Between Biofouling Adhesion And Frequency Of Mechanical Cleaning To Control The Recruitment To Clear Coatings, Dylan Thomas Eggers
The Relationship Between Biofouling Adhesion And Frequency Of Mechanical Cleaning To Control The Recruitment To Clear Coatings, Dylan Thomas Eggers
Theses and Dissertations
There is a need to control biofouling on sensors and transparent windows in the marine environment. Clear silicone coatings offer a method to reduce the adhesion strength of marine organisms to the surface, however, these also require mechanical cleaning to maintain the surfaces free of fouling. This research evaluated the performance of eighty seven formulations and took the top two candidates to investigate a) the frequencies of wiping required by a brush to maintain two coatings and uncoated glass surfaces free of fouling and b) the effects of clear silicone coatings fouling release properties on required frequencies. The panels were …

Journal of Marine Science and Technology
Marine macroalgae generally keep their surface free from fouling organisms by their antifouling defence. Antifouling activity has been attributed to the production of secondary metabolites. In the present study, antifouling performance of the macroalga Halimeda sp., collected from the Red Sea coastal waters, was assessed using extracts prepared through various methods, including surface extraction, wet sample extraction and dried sample extraction. The solvents methanol and hexane were used to assess the effect of solvents on bioactivity. Results indicated that extracts of the macroalga inhibited growth and settlement of a biofilm-forming bacterial strain. Though the extracts prepared using different methods and …
Rearing Temperature Affects The Expression Of Proteins In The Adhesive Of The Striped Acorn Barnacle, Balanus Amphitrite, Melissa J. Daugherty
Rearing Temperature Affects The Expression Of Proteins In The Adhesive Of The Striped Acorn Barnacle, Balanus Amphitrite, Melissa J. Daugherty
Master's Theses
Barnacles are dominant hard–fouling organisms in marine waters. They attach to substrates by secreting a complex proteinaceous adhesive. Understanding the chemical composition of this multi–protein underwater adhesive and how it is affected by environmental variables, such as oceanic temperatures, is critical for developing nontoxic solutions to control biofouling. Previous experiments in our lab revealed an inverse relationship between critical removal stress (CRS) and temperatures at which barnacles were reared. Further investigations showed that this correlation is not attributed to differences in physical properties such as barnacle size or short–term changes in the viscosity of adhesive. Therefore, the observed effects may …
Investigation Of Larval Sensory Systems In The Marine Bryozoan, Bugula Neritina, Heather Leigh Price
Investigation Of Larval Sensory Systems In The Marine Bryozoan, Bugula Neritina, Heather Leigh Price
Master's Theses
Bugula neritina is a sessile marine bryozoan with a pelagic larval stage. Larvae frequently settle on boat hulls, facilitating the introduction of B. neritina to bays and estuaries worldwide. Adrenergic agonists, such as the vertebrate hormone noradrenaline, inhibit larval settlement in a variety of marine invertebrate species, including B. neritina. Light also inhibits B. neritina larval settlement, yet the underlying mechanisms by which light and adrenergic compounds exert their effects on larvae are not well understood. Octopamine is considered the invertebrate analog of noradrenaline, and may be an endogenous hormone involved in larval settlement pathways. I observed the effects of …
Ultraviolet Led Biofouling Mitigation, Andrew Lam
Ultraviolet Led Biofouling Mitigation, Andrew Lam
Computer Engineering
The goal is to determine if low-cost UV LEDs can mitigate marine biofouling on small glass or acrylic camera lenses. A microprocessor-controlled experimental setup to control the illumination of low-cost UV LEDs of various wavelength and packaging was fashioned. The system consists of a programmed microcontroller, a manufactured LED breakout interface, and a submergible UV LED array enclosed in a borosilicate glass tube. A preliminary qualitative assessment of four different UV LEDs was conducted during a three-week deployment of the experimental setup in the raw seawater system at the Cal Poly Center for Costal and Marine Sciences in Avila Beach, …
