Nitrogen Pollution in Tropical Coral Ecosystems

Jessica Arnull is a dedicated marine ecologist pursuing her PhD at the University of Edinburgh, where she investigates the impacts of nitrogen pollution on coral reefs and seagrass ecosystems in South Asia. Her academic journey includes an undergraduate degree in Geography from the University of Bristol and an MSc in Marine Systems and Policies from the University of Edinburgh. As a qualified secondary school Geography teacher, she integrates education as a fundamental aspect of her research work. Her research portfolio includes significant contributions to understanding marine ecosystems, notably her work on how sea cucumber farming (Holothuria scabra) positively influences seagrass growth rates, and her comprehensive analysis of anthropogenic nitrogen pollution's effects on South Asian coral reefs. Her fieldwork spans multiple global locations, including Madagascar, the Maldives, and Australia, where she focuses on coastal biogeochemistry and blue carbon ecosystems. Arnull's research is particularly centered on developing nature-based solutions for marine conservation and coastal livelihood adaptation in response to climate change challenges. She currently contributes to the South Asian Nitrogen Hub project, combining her expertise in seagrasses, coral reefs, coastal biogeochemical cycling, and interdisciplinary approaches to address pressing environmental challenges.
