New MBARI project: The Emerging Science of a High CO2 / Low pH Ocean

This project developed by the Monterey Bay Aquarium Research Institute (MBARI) proposes to tackle the problem of assessing the future impacts of elevated oceanic CO2 levels (lower pH) on marine ecosystems through a unique combination of field and laboratory studies, and to address the associated policy, economic, and permitting issues. This work will draw on […]

Climate change will leave a sour taste in our mouths – literally: Study shows ocean acidification affects the flavour of shellfish

It is a popular appetiser at this time of year, but Marie Rose could soon be a lot less paletable, according to a new study.
