Programme overview
What is the Diploma in Ocean Acidification and Deoxygenation?
The Diploma in Ocean Acidification and Deoxygenation
Prepares you to understand, measure and communicate two of the most profound changes the ocean is undergoing: acidification and oxygen loss. You will study carbonate chemistry, the drivers of coastal and open-ocean deoxygenation, their effects on organisms, ecosystems, fisheries and aquaculture, and the observation and monitoring networks that detect them, so that you can propose realistic management and adaptation measures for the coasts and seas you work in.
Key advantages
- Two linked processes: Acidification and deoxygenation studied together, as they occur in the ocean.
- Clear chemistry: From the carbonate system to dissolved oxygen, without unnecessary formulae.
- Real impacts: Effects on calcifiers, fisheries and aquaculture.
- Open data: Work with observation time series and international databases.
- Case study: Diagnosis of a vulnerable coastal area.

Entry Requirements
No. The programme reviews the basics needed to understand the carbonate system and dissolved oxygen.
Yes. You use observation time series and open international databases.
Yes. It includes specific content on monitoring and adaptation on marine farms.
Acidification depends mainly on cutting CO2 emissions; coastal hypoxia can improve with nutrient control. Both are explained with their limits.
