Submitting data to assess OA globally
Background
In 2015, the United Nations adopted the 2030 Agenda and a set of Sustainable Development Goals (SDG), including a goal dedicated to the ocean, SDG 14, which calls to “conserve and sustainably use the oceans, seas, and marine resources for sustainable development”. Under this SDG 14, there are 10 Targets addressing a range of ocean issues and 10 Indicators, which are the measurable components of the Target. The Intergovernmental Oceanographic Commission (IOC) of UNESCO was identified as the custodian agency for the SDG Target 14.3: “Minimize and address the impacts of ocean acidification, including through enhanced scientific cooperation at all levels”, and the associated SDG Indicator 14.3.1 (“Average marine acidity (pH) measured at agreed suite of representative sampling stations”).
The SDG 14.3.1 Indicator Methodology provides the necessary guidance on how to conduct ocean acidification observation. The Methodology contains guidance on sampling strategy, measurement methods and calculation, methodology and instrumentation, links to community agreed Best Practices and Standard Operating Procedures, data quality categories and data quality control mechanism as well as recommendations for the calculation of the seawater carbonate system, including how to account for the uncertainty of measurements. It further offers support on how to and what kind of data sets to submit to IOC, to ensure the production of quality-controlled global and possibly regional products of surface ocean acidification.
The full text of the Methodology as well as the data template, the metadata template and the metadata instructions files can be downloaded from the SDG 14.3.1 Data Portal website (https://oa.iode.org/). The SDG 14.3.1 Data Portal is a tool for the submission, collection, validation, storage, and sharing of ocean acidification data and metadata submitted towards the SDG 14.3.1 Indicator.
This present document is an introduction to the SDG 14.3.1 Methodology, providing an introduction to some aspects of the guidance provided within the Methodology. This document should therefore not replace the Methodology; please make sure to read and apply the SDG 14.3.1 Methodology elaborated here.
