The Global Ocean Acidification Observing Network Executive Council discussed and finalized a methodology for collecting information on global ocean acidification, in support of monitoring SDG target indicator 14.3.1.

The Network is also working to build the capacity of scientists to collect reliable, globally comparable data on the indicator.

11 June 2018: Experts from the Global Ocean Acidification Observing Network (GOA-ON) Executive Council finalized the methodology for the SDG target indicator 14.3.1 on marine acidity. The UN Educational, Scientific and Cultural Organization’s Intergovernmental Oceanographic Commission (UNESCO-IOC) is the custodian agency for the indicator.

The GOA-ON, a collaborative international network of 475 members from 80 nations, is committed to increasing global ocean acidification observation capacity in support of SDG target 14.3, which calls to “minimize and address the impacts of ocean acidification, including through enhanced scientific cooperation at all levels.” SDG target indicator 14.3.1 focuses on “average marine acidity measured at an agreed suite of representative sampling stations. It is within the Sustainable Development Goal on life below water (SDG 14).

In the 14.3.1 indicator methodology, experts provide detailed guidance to scientists and countries on how to carry out measurements in line with best practices established by the ocean acidification community. The methodology outlines how to collect information that is transparent, traceable and globally comparable. According to the IOC, improved observation and research on ocean acidification is critical for supporting scientific and governmental efforts towards climate adaptation and mitigation.

The GOA-ON Executive Council also discussed efforts to increase global ocean acidification observing capacity, in line with the Council’s UN Ocean Conference Voluntary Commitment. As part of its commitment, the GOA-ON is working to build capacity in regions that have limited observation and limited ocean science capacity. The Council and its Secretariat are organizing capacity building workshops on ocean acidification monitoring and experimentation best practices and providing sensor kits to allow scientists to collect reliable data and contribute to the global ocean acidification monitoring effort.

The GOA-ON Secretariat includes the IOC of UNESCO, the U.S. National Oceanic and Atmospheric Administration (NOAA), the University of Washington in Seattle, Washington, US and the Ocean Acidification International Coordination Centre (OA-ICCC) in Monaco.

The Executive Council’s Fifth Annual Meeting convened from 28 to 30 May 2018 in Sopot, Poland. [UNESCO Press Release] [GOA-ON Executive Council Website] [GOA-ON Commitment]
