Climate Change: Ocean Acidification and Warming

saba 5

Human activities are driving a rapid increase in atmospheric carbon dioxide (CO2), resulting in elevated global temperatures and ocean acidification. Elevated temperature and decreased seawater pH can impact several important processes in marine organisms including calcification rates, metabolic physiology, and indirect impacts via qualitative and/or quantitative changes in food source. Through field and laboratory experiments, we investigate organismal response to individual and synergistic changes in temperature and seawater pH. We are also interested in utilizing ocean observing technologies (AUVs, moorings, sensor development) to determine natural environmental variability near organism habitats that will provide a framework to better study organism response and design more realistic experiments.
