A global study of productivity, deoxygenation and ocean acidification at selected sites (2017-underway)

The oceans, with their high biodiversity and highly productive resources, provide important ecosystem services, these ecosystems have naturally adapted to the climatic variations that occur at different spatial and temporal scales, which manifest in changing biological properties, algal blooms, and declining levels of oxygen and acidity. Despite active oceanographic research related to climate change, there remain significant gaps in our knowledge of the adaptability and resilience of ecosystems to climate change, hence a Global Network will allow us to advance the knowledge and benchmarking of the oceans and major seas (i.e. Mediterranean Sea), by creating, where needed, data bases of the basic oceanographic variables (e.g. temperature, salinity, dissolved oxygen, chlorophyll concentration) and consolidating existing ones. The proposed global network will benefit from the previous NANO regional projects that included a strong observation component (e.g. NANO-Africa, NANO-Latin America projects). Therefore, the proposed global observation project is seen as the continuity of previous NANO regional projects that started gathering data during the last few year and helped several countries participating in NANO projects to acquire observation equipments. Also most importantly, this global project will build upon existing observation networks such as the Antares network.


  • Promote in situ and remotely sensed observations of the ocean at selected coastal sites in order to contribute to the global effort of monitoring the levels of ocean acidification and deoxygenation;
  • Provide opportunities to the project participants for capacity building to strengthen their efforts to monitor levels of acidification and oxygenation and to join larger observation networks of ocean acidification and deoxygenation (e.g. NANOOS, BIO-ACID);
