A global study of coastal Deoxygenation, Ocean Acidification and Productivity 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, databases of essential oceanographic variables (e.g. temperature, salinity, dissolved oxygen, pH, chlorophyll concentration) and consolidating existing ones.

NANO-DOAP project benefits 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.

NANO-DOAP Project aims to: 1) promote in situ and remotely sensed observations of the coastal ocean at selected coastal sites; 2) provide opportunities to the project participants to strengthen their efforts to monitor essential ocean variables; and 3) organise activities where members can share experiences and best practices, as well as compare results from local analysis, producing global results.


The NANO-DOAP Project began in April 2017 as the continuity of the previous regional observation projects funded by NF-POGO. The general objectives of NANO-DOAP are:

  • Support in-situ measurements of selected Essential Oceanographic Variables (EOVs) at participant study sites.
  • Compile data submitted by the participants into a NANO global database of selected EOV and support comparative analyses among study sites, focusing on levels of productivity, acidification and deoxygenation.
  • Provide capacity building opportunities to the project participants on marine data management and observation and data analysis methods through workshops and webinars.
  • Initiate and promote outreach and citizen-science activities to raise awareness about the importance of the marine environment and the threats facing it.

Specific objectives for the current year (April 2020 – March 2021) are:

  • Continue to support the on-going bimonthly sampling in 16 study sites.
  • Improve NANO-DOAP measurement network by involving more NANO members, especially from countries in Africa, Latin America and South-East Asia.
  • Compile and analyse the data collected by all participants.
  • Prepare a second round of NANO Global Project Webinar Series.
  • Organize the second meeting of the NANO-DOAP tentatively in June 2020, hosted by NGP participants intuitions.
