The influence of phytoplankton productivity and molecular physiology on biogeochemical dynamics of two contrasting ocean environments Understanding the controls on oceanic primary production is crucial to elucidating it’s influence on global biogeochemical cycling, ocean health, and climate regulation under current … Continued
The environmental health of aquatic ecosystems is threatened by the global proliferation of cyanobacterial harmful algal blooms (CHABs) in key drinking water and recreational water resources. In recent decades, the occurrence of CHABs has increased spatiotemporally due to climate change … Continued
Abstract: Coastal foredunes, which arise from feedbacks between sediment transport and vegetation, protect coastal habitats and coastal development from storm impacts. The rate of dune growth and dune shape are influenced by the morphology of the dune-building grasses that give … Continued
Drivers of Microbial Diversity in the Temperate Coral Oculina arbuscula Abstract: Disruption of the coral-algal symbiosis (bleaching) in response to anthropogenic stressors, such as warming and nutrient pollution, represents a significant threat to coral reefs worldwide. Corals are complex meta-organisms … Continued
Wave transformation in coastal marshes Amid increasing frequency and intensity of storms, there is a growing need for resilient shoreline protection strategies, especially those that can also provide ecological and economic benefits to coastal communities. Coastal marshes, whether restored, … Continued
Comparison of edge effects across patchy and contiguous seagrass landscapes Abstract: Coastal marine habitats are subject to fragmentation from a variety of processes including human-induced disturbances such as dredging and natural processes such as high-energy storms. It is widely accepted … Continued
Survey of epiphytic microalgae to evaluate risk of ciguatera fish poisoning across natural and artificial reefs in North Carolina Epiphytic microalgae are important contributors to the carbon and nutrient cycles, yet are often overlooked during ecological surveys. In reef habitats, … Continued
Determining carbon sequestration in reservoirs: A quantitative 210Pb-based approach As carbon emissions continue to rise, much work has been done to properly quantify carbon sources and sinks to better understand the carbon cycle and how it responds to the … Continued
The convergence of different water masses on the shelf and along the shelfbreak, and cross-isobath shelf-open ocean exchanges contribute to the complex circulation near Cape Hatteras. To better understand the exchange between the continental shelf and the adjacent open ocean … Continued
Dissertation title: Marine ecosystems through the lens of soundscape ecology: How biological processes, landscape structure, and anthropogenic activity affect spatiotemporal soundscape patterns Dissertation Abstract: Marine soundscapes, or the collection of all sounds across a landscape, consist of dynamic patterns resulting … Continued
