Geographically and environmentally driven spawning distributions of tuna species in the western Mediterranean Sea

Creator:: Reglero, Patricia, Ciannelli, Lorenzo, Alvarez-Berastegui, D., Balbin, R., Lopez-Jurado, J. L., and Alemany, F.
Abstract:: The spawning habitats of many large marine pelagic predators are poorly known. This lack of knowledge hampers conservation efforts that are aimed at identifying critical habitats for the spawning of these species. We hypothesized that phylogenetically related species show different adaptations and respond differently to environmental and geographical cues for...

Southern Ocean Science and Society: Case Studies at the Nexus of Research, Education, and Policy

Creator:: Hann, Ashley M.
Abstract:: Even in remote environments, human and natural systems are connected. Pressing environmental and social changes warrant the field of science to not only continue to enhance understanding of the natural world, but also consider the socio-ecological implications of research in the coupled human-natural system. Additionally, a need exists for communication...

Applying a Dynamic Time Warping Approach to Stratigraphic Correlation: Quaternary Magnetostratigraphy and Ediacaran–Cambrian Chemostratigraphy

Creator:: Hagen, Cedric J.
Abstract:: Magneto- and chemostratigraphic correlation underpins much of our understanding of Earth history, yet typical correlation techniques are neither quantitative nor objective. Within this dissertation, I detail my efforts to develop and apply dynamic programming-based algorithms that accomplish optimal and reproducible stratigraphic alignment. I apply these algorithms to three geologic intervals:...

From Micro to Macro: Insights into Biogeochemical Mechanisms that Shape Marine Systems

Creator:: Seabrook, Sarah
Abstract:: Biogeochemical mechanisms employed by key organisms, or symbiotic associations of organisms, transform the function and structure of their environment through processes recognized as ecosystem engineering. This dissertation seeks to investigate organism-ecosystem interactions that serve globally significant ecological functions in marine systems and impact how systems respond to environmental change. Using...

Marine Neritic and Epipelagic Community Dynamics: An Investigation of the 'Yin' and 'Yang', No-Analog, and Refugia from a Multi-species Perspective

Creator:: Barceló, Caren
Abstract:: Changes in ocean conditions influenced by climatic fluctuations have lead to changes in individual species distributions, which alter the diversity, communities and species interactions across marine ecosystems worldwide. Assessing the species composition and identifying regions and habitats that can safeguard the persistence of biota are critically important. In this dissertation,...

Assessment of Extraterrestrial Tracers Ir, Pt and ³He in Polar Ice Cores

Creator:: Mehmel, Nicholas C.
Abstract:: This thesis focuses on the investigation of extraterrestrial tracers Ir, Pt and 3He in polar ice cores. These tracers may be used to identify characteristics of interplanetary dust particles, and to quantify the flux of extraterrestrial material during impact events, certain volcanic eruptions, and stable background periods. In the first...

An Exploration of Climate Change, Conservation, and Cooperation, in Three Essays

Creator:: Johnson, Steven Mana'oakamai
Abstract:: The defining feature of our planet are the oceans, which make up 70% of the Earth’s surface. The importance of the ocean cannot be understated: 50% of oxygen originates from phytoplankton; heat is absorbed and redistributed by ocean currents; and hundreds of millions of people rely on the ocean for...

Optics, structure and variability of the offshore Columbia River plume

Creator:: Saldías, Gonzalo
Abstract:: The Columbia River delivers the greatest amount of freshwater to the coastal ocean along the U.S. Pacific coast. This freshwater forms the Columbia River plume, a mesoscale plume with significant implications on coastal ocean physical, biological, chemical, and geological processes. The plume is transported south and offshore during the upwelling...

Planning for Change: Assessing the Potential Role of Marine Protected Areas and Fisheries Management Approaches for Resilience Management in a Changing Ocean

Creator:: Kroeker, Kristy J., Carr, Mark H., Raimondi, Peter T., Caselle, Jennifer E., Washburn, Libe, Palumbi, Stephen R., Barth, John A., Chan, Francis, Menge, Bruce A., Milligan, Kristen, Novak, Mark, and White, J. Wilson
Abstract:: Despite progressive policies and continued advances in ocean management, numerous shifts associated with global changes have been observed in marine ecosystems in recent years, including warming, ocean acidification, and deoxygenation. As global change accelerates, science is needed to inform evidence-based management strategies for continued ecosystem services. Resilience management, in which...

An Exploratory Study on Family Group Use of a Multi-touch Table Exhibit at a Public Marine Science Center

Creator:: East, Jennifer L.
Abstract:: Museums, aquariums, and technology centers are informal learning environments that facilitate the understanding of scientific phenomena while supporting self-motivated learning. Families are a social group that frequently visits these sites. There are multiple opportunities for adults and children to engage in independent sense-making and collective discussion about their experiences with...
