The overall goal of the Oceans and Human Health Center on Climate Change Interactions (OHHC2I), Administrative Core is to assess climate change effects on ocean health related Illness (e.g. Vibrio bacteria and Cyanobacteria (Microcystis aeruginosa, Cylindrospermopsis raciborkii and Anabaena flos-aquae) disease (e.g. Vibrios infections, Cyanobacterial toxins and microplastic exposure singularly and in combination, on nonalcoholic liver disease and seafood safety) and to develop Prevention Strategies (models, forecast and education tools) which warn at risk populations and better protect public health. The role of the Administrative Core (AC) is to ensure the full integration of the four Research Projects (Vibrio Bacteria, Cyanobacteria, Chemistry and Toxicology) and the Community Engagement Core (CEC) with all internal and external partners into one thematically driven research Center which can address immediate and long terms effects of climate change on coastal ocean science and public health.
