Kev's Dinghy Boat Workshops, Ruiyang Xiao

Masters Theses

In a culture where convenience replaces process, this project argues that making — even when inefficient, imperfect, or unnecessary — enables forms of engagement that buying cannot.

Technologies and Services nowadays are able to fulfill human’s desire to travel and explore at ease. However, this convenience proposes a mode of engagement based only in deeper knowledge of context and thus our experience with the world around us is hence diminished. Our engagement with the world becomes heavily mediated, regulated and controlled.

This project investigates how hands-on engagement with water can reintroduce + restore our sense of joy, curiosity, consequence, and …

A Sturdy Future: Mangrove Restoration Against Climate Extremes, Gabriella Marie Siasoco

Student Theses 2015-Present

This paper addresses the impacts of climate change on natural disasters and examines how rehabilitation of mangrove forests in Mesoamerica and the Caribbean can mitigate those effects. Rising ocean and atmospheric temperatures contribute to higher sea levels and more severe hurricanes and tropical storms, characterized by increased frequency, duration, and intensity in peak winds, storm surges, and rainfall. Mangrove ecosystems act as vital buffers against coastal disturbances such as tsunamis and extreme storms, while contributing to climate change mitigation through carbon sequestration. Additionally, they improve water quality by filtering nutrients, preventing eutrophication. Despite their ecological and economic value, mangroves in …

The Effects Of Impervious Land Cover And Red Tide (Karenia Brevis) On The Florida Manatee (Trichechus Manatus Latirostris) In The Gulf Coast Of Florida, Anna Compton

Honors College Theses

Red tide, caused by the dinoflagellate Karenia brevis, is an algal bloom event that occurs annually in the West Florida Continental Shelf. The algae releases brevetoxin, a toxin that can be fatal to wildlife in high concentrations. These algal bloom events are thought to be exacerbated by warming ocean temperatures and increased nutrient runoff from urbanization. Red tide is responsible for the mass mortality of various marine organisms like the Florida manatee (Trichechus manatus latirostris). This study analyzes the changes in nutrient runoff and sea surface temperatures, and how these factors affected red tide cell concentrations and Florida manatee mortalities …

Trawling For Clues: Examining Nefmc Herring Amendment 8, Christopher Santoro

Honors Scholar Theses

In 2007, almost twenty years ago, the Magnuson-Stevens Act changed the landscape of fisheries management in the US. Through the establishment of Fisheries Management Councils (FMCs), it paved the way for top-down management approaches that helped the government combat nationwide declines or collapses in fish stocks. Among the myriad responsibilities of the FMCs was the expectation that amendments to existing fisheries management plans would be a necessity to adapt to modern circumstances. This thesis focuses on New England Fisheries Management Council's (NEFMC's) Herring Amendment 8 (A8). This amendment, passed in 2021, attempts to lay the groundwork for sustainable management of …

Frontiers In Ocean Non-Equilibrium Dynamics And Challenges In Operational Oceanography Application, Yuhong Zhang, Yan Du, Tianyu Wang, Minyang Wang, Qin Duan, Xinlong Li, Yuhang Zheng, Yifan Xia, Shilin Tang, Yineng Li, Jianping Yin

Bulletin of Chinese Academy of Sciences (Chinese Version)

Ocean circulation exhibits complex multiscale dynamics, among which non-equilibrium processes, marked by transient behavior, strong perturbations, and pronounced nonlinearity, are of particular importance for maritime environmental support. However, limited observational capability has long constrained the study of subsurface non-equilibrium dynamics, leaving numerical models insufficiently validated and positioning this issue at the forefront of modern physical oceanography. Artificial intelligence (AI) offers a promising pathway to overcome this bottleneck. Built on this concept, the “iEddy” AI large ocean model can efficiently reconstruct high-resolution, high-accuracy three-dimensional temperature, salinity, and velocity from sea-surface remote sensing data, demonstrating strong capability in capturing non-equilibrium ocean currents …

Cephalopod Consciousness: Asking The Right Questions, Gordon Burghardt

Animal Sentience

Jennifer Mather has provided a comprehensive and fascinating overview of the various cognitive accomplishments of cephalopods and their sensory, behavioral, and neurophysiological attributes. The advances in our understanding of a clade that has been separated from vertebrate evolution by well over half a billion years is a testament to advances in both methodology and the questions we now feel free to address. Mather embeds her review in the issue of consciousness, which is certainly a perennial issue in mental evolution, going back to Romanes and earlier. I argue that the term “consciousness” has such a checkered history and is used …

Meeting Carbon Dioxide Removal Demand In 2030: The Potential Of Macroalgae Cultivation And Harvest, Lotta Siebert, Jiajun Wu, Lena-Katharina Bednarz, David Keller, Felix Meier, Christine Merk, Sonja Peterson, Wilfried Rickels

Journal of Ocean and Coastal Economics

A growing number of countries have announced net-zero and net-negative emissions targets, but only a few countries provide incentives for carbon dioxide removal (CDR). We derive estimates of countries' hypothetical demand for CDR in 2030 based on their emissions reduction targets under the Paris Agreement. The aggregated average global demand for CDR in the compliance year 2030 is 1064 MtCO₂, 353 MtCO₂, and 124 MtCO₂ for the low, medium, and high-cost CDR scenarios, respectively. This demand comes exclusively from countries and regions with relatively high GDP per capita, relatively high abatement costs and a limited …

Under The Bay: Analysis Of Green Sea Turtle (Chelonia Mydas) Dive Behavior In The Urban San Diego Bay, Emily Carter

Theses

Sea turtles are air-breathing marine reptiles that spend their lives performing dives to travel, forage, and rest. Several dive types have been previously recorded for sea turtles, each type being associated with a different set of behaviors. U-dives, or Type 1 dives are widely characterized by extensive benthic periods preceded by and concluding with abrupt descent and ascent phases respectively (Minamikawa et al. 1997; Houghton et al. 2002; Seminoff et al. 2006). These dives are widely affiliated with turtle resting behavior though can be indicative of additional activities including benthic travel and foraging. Previous research of green turtle dive behavior …

Pygoscelis Penguins Prefer Different Oceanographic And Terrestrial Habitats During The Austral Summer, Katherine L. Gallagher, Rachel Herman, Katherine Walton, Michael S. Dinniman, Heather J. Lynch

OES Faculty Publications

Pygoscelis penguins interact with both terrestrial and marine environments, especially during the austral summer when they raise their chicks. Accessible ice-free ground spaces serve as locations for penguins to build colonies and successfully raise chicks while the surrounding marine environment serves as the foraging grounds for adult birds. Penguins must be able to navigate through the waters around their colonies to forage for Antarctic krill (Euphausia superba), their primary prey during the austral summer. Krill, whose distributions are driven partially by the surrounding physics and partially by their behaviors, must also be plentiful in the waters near the …
