VI. Climate Change Related Research

 We are conducting marine environmental studies and experimental studies on the effects of carbon dioxide (CO2) on marine organisms to investigate techniques for forecasting or mitigating the impact on marine organisms of CO2-driven climate-change and the resulting perturbations in the marine environment.

Marine Environmental Surveys
 Carbon capture and storage is a climate change mitigation strategy. The MERI is investigating the potential impacts of sub-seafloor carbon dioxide storage on water quality, bottom sediments, organisms, and other aspects of the marine environment.

CO2 Impact Studies Using Marine Organisms
 As the atmospheric CO2 concentration increases, there is an accompanying increase in CO2 dissolved in the oceans. This drives the gradual change in pH of seawater towards neutral conditions from basic. In an effort to determine the impact of these environmental changes on marine organisms, the MERI is conducting CO2 impact studies on bivalve growth and fish breeding. Moreover, we are also participating in experiments at several locations across the country to determine rates of recruitment and settlement of sessile organisms in high-CO2 water in an effort to predict the impact of ocean acidification on marine ecosystems.
