The Green Sea Turtle
Get PDFArtist Statement
The Green Sea Turtle is a piece I produced as a part of my final portfolio for the Scientific Illustration course I participated in during the summer semester of 2022. The Green Sea Turtle is a watercolor and gauche painting on Bristol paper that was created as part of a collection representing each of the five sea turtle species native to the Florida coasts. Green sea turtles (Chelonia Mydas) are the largest species of hard-shelled turtle in the world, they are also unique because of their specialized diet which consists primarily of sea grass and algae. Green sea turtles, like all sea turtle species, are endangered due to human impacts. Green sea turtle populations have been devastated as a result of hunting, pollution, and habitat loss and it is estimated that fewer than 100,000 nesting females remain in the world today.
I was inspired to paint this piece after spending a year as an intern at the Marine Science Center (MSC) in Ponce Inlet, Florida. During my time at MSC, I worked up close with sick and injured sea turtles, including many green sea turtles. The most frequent cause of injury to these animals was discarded plastics which they either ingested or became entangled in. It was deeply upsetting to see so many of these beautiful animals dead or injured because of human carelessness. I want to help raise awareness for how serious the problem of plastic pollution truly is. I hope by creating art like this piece I can help people to feel a deeper connection with these majestic creatures, even if they never get the chance to interact with them personally. In some small way, I hope I can do my part to motivate people to be more conscious of their choices when it comes to the products they buy and the people they vote for.
I am a junior at the University of North Florida where I am majoring in biology, with a concentration in coastal and marine biology, and minoring in environmental studies. As a science major, I felt I had to give up most of my more creative, artistic interests but participating in the Scientific Illustration course helped open my mind to new possibilities of how I can combine art and science to help reach people about issues in our environment. I am extremely passionate about educating people and communities about endangered species, pollution, and climate change. I feel we are at a critical turning point regarding our environment, and it is vital that we take steps towards protecting our planet before it is too late. After graduation, I plan to continue working with marine animals and I hope I will be able to inspire more people to care for the planet through my art
Analysis of Pervious Oyster Shell Habitat (POSH) Unit Performance Using Computational Fluid Dynamics
No full textIn recent years, pervious oyster shell habitat (POSH) units have been developed and deployed as part of living shoreline projects in Northeast Florida. POSH units are modular artificial oyster reef structures made from cement and recycled oyster shells. POSH units aim to attenuate wave energy, trap sediment, restore salt marsh habitat, and improve oyster recruitment. Previous studies demonstrated the units’ ability to attract oyster larvae and reduce shoreline bed stress in some areas. This paper looks to further understand the effect of POSH unit placement on bed stress under boat wake conditions using computational fluid dynamics (CFD). Results indicated that certain POSH unit arrangements may be preferable; a small overlap may help block flow and reduce associated stresses, while a chevron pattern may benefit sites subject to oblique waves. Understanding how POSH units affect bed stress and erosion patterns can help restoration stakeholders design future living shorelines with POSH units or other similar structures
Analysis of Underwater Noise due to Pile Driving in Florida using Individual Hammer Blows
No full textIn recent years, the potential impact on marine organisms of sound waves generated by pile driving has become a growing concern. Previous research in this field has predominantly relied upon single-strike averages to analyze underwater sound data. However, it was unclear from these analyses if or how much attenuation may vary during typical pile drives. This study involved collecting sound data from multiple locations during a given pile driving operation at the same time and used these data to analyze sound decay from each hammer blow individually. In addition to this, computational fluid dynamics (CFD) was used to better understand the components that may influence attenuation variability. The results reveal that each hammer blow exhibits a unique sound decay curve characterized by a distinct sound attenuation coefficient. Interestingly, these coefficients demonstrate variability within a drive event. Several potential factors contributing to these variations are identified, including the type of pile, variation in geotechnical conditions, hammer cushion, pile cushion, and channel properties. However, despite the variability observed in attenuation coefficients from one blow to another, an apparent relationship was consistently observed between source-level and attenuation – thereby providing additional basis for a previously proposed empirical model for predicting underwater attenuation. This emphasizes the need for further research in establishing exactly whether source level influences sound attenuation or if mode stripping variation is governed by additional sound attenuation
