Personality and affiliation involving a cooperative task in bottlenose dolphin (Tursiops Truncatus) Dyads
… dolphin pairs at the Roatan Institute for Marine Sciences (RIMS), Honduras, were presented with an apparatus released a food reward if opened cooperatively. I created personality profiles of each dolphin with traits grouped in two different contexts: dolphin-dolphin and dolphin-world. I …

Same-Sex Socio-Sexual Interactions Among a Group of Captive Bottlenose Dolphins (<i>Tursiops truncatus</i>)
… dolphins housed at the Roatan Institute for Marine Sciences (RIMS), collected between March of 2010 and May of 2013, was analyzed. Associations occurring during homosexual interactions were transitory for most individuals. Nonetheless, subsequent analyses allowed the rejection of the null …

Battery-Free Wireless Imaging of Underwater Environments
… environments is of great importance to marine sciences, ocean sustainability, climatology, defense, marine robotics, geology, space exploration, and global food security. Despite advances in underwater imaging, most of the ocean and marine organisms remain unobserved and undiscovered. …

The Nature of Social Relationships in Bottlenose Dolphins (<i>Tursiops truncatus</i>): Associations and the Role of Affiliative, Agonistic, and Socio-Sexual Behaviors
… dolphins housed at the Roatan Institute of Marine Sciences, collected in 2010, provided 10.5 hours of underwater footage for assessment of association coefficients and proportions of interactions. These data suggested similar patterns to previous studies on bottlenose dolphin association …

Using Personality Traits to Predict Pectoral Fin Contact Initiation Role in Bottlenose Dolphins (<i>Tursiops truncatus</i>)
… under human care at the Roatan Institute for Marine Sciences (RIMS) between 2014 and 2017. Personality assessments were conducted by experienced trainers for dolphins using rating questionnaires that reflected the personality traits from the Five-Factor Model (i.e., Extraversion, …

Distributed approaches for coverage missions with multiple heterogeneous UAVs for coastal areas.
… to a wide variety of problems. Regarding marine sciences and more generally coastal or sea operations, the use of aerial robots brings forth a number of advantages, including information redundancy and operator safety. This Thesis initially deals with complex coastal decomposition in …

Exploring Phosphorus Dynamics in Mid-Atlantic Soils: A Multi-Scale Analysis Integrating Soil Fertility and Land Management for Environmental Sustainability
… quality data from the Virginia Institute of Marine Sciences and GIS technology to analyze the impact of land use and land cover (LULC) on nitrogen (N) and P concentrations in 52 watersheds. Row crop LULC was significantly correlated with higher total nitrogen (TN) concentrations (p = 0.03), …

Radium isotopes as tracers of boundary inputs of nutrients and trace elements to the coastal and open ocean
Nutrients and trace metals are vital for supporting life in the ocean, but the boundary processes that control the distributions of these elements are poorly constrained. Radium isotopes are well suited to studying inputs of elements from ocean margins because they are produced in sediments and …

Turbulence in the sea ice impacted Southern Ocean and its implications for primary production and carbon export
The sea-ice impacted Southern Ocean, south of the Antarctic Circumpolar Current, is one of the most important regions on earth for the cycling of carbon and distribution of heat and freshwater around the globe. Here, along-isopycnal upwelling of warm, carbon-rich circumpolar deep water coincides …

Dynamics and kinematics of an estuarine network
This thesis addresses the dynamics of estuarine networks, based on hydrographic observations in Newark Bay, a sub-estuarine network connected to the Hudson River estuary through New York Harbor. Estuarine networks differ from simple estuaries in that they may have multiple connections to the ocean, …
