Document Summary

Impacts of ocean warming and acidification on marine ecosystems. Studied a broad area of marine science. Joe d. and helen j. kington professor in environmental change. Ocean acidification = how rising atmospheric co2 is affecting ocean chemistry. Almost to a 50% increase in co2. One of the primary human drivers of climate change. Rate of increase in unprecedented in geologic record. Haven"t seen these levels of co2 in millions of years. Putting stress on a variety of organisms. As atmospheric co2 levels increase, the ocean serves as a carbon sink. Biological pump: carbon dioxide in the deep ocean does not react with the atmosphere. He creates models on effects of climate change on the oceans, adds components relevant to society (fisheries, algal blooms, natural resources, etc. ) It is time to take earth system models and morph it into direct societal impacts (coastal hypoxia, sea level rise, etc. ) Ocean carbon uptake about 1/3rd of human emissions.
