The general IOC data collection process is described in Document IOC-XXIX/2Annex 14.

The novelty of assessing ocean acidification at the global level, as in indicator 14.3.1, requires the IOC secretariat to collect the data via different pathways. Data collections are a mixture of:

direct requests to National Statistical Offices (NSOs), as new national reporting mechanisms are now installed allowing them to provide the required information (from the 2021 data collection onwards),
annual requests to the IOC national focal points,
collaboration with National Oceanographic Data Centres, international data centres and
directly with data providers via the GOA-ON data portal (Figure 1).

Figure 1. Scheme to illustrate the proposed data collection and publication process related to national contributions of data related to 14.3.1 (SDG: Sustainable Development Goal; IOC-UNESCO: Intergovernmental Oceanographic Commission of UNESCO; GOA-ON: Global Ocean Acidification – Observing Network; JCOMM: WMO-IOC Joint Technical Commission for Oceanography and Marine Meteorology; WMO: World Meteorological Association; IODE: International Oceanographic Data and Information Exchange of IOC UNESCO; GDAC: Global Data Assembly Center; BGC ARGO: Biogeochemical Argo floats; QC: Quality Control; NODC: National Oceanographic Data Centre; DOI: Digital Object Identifier; BP: Best Practice; CD: Capacity Development; PI: Principal Investigator; RTC: Regional Training Centre).

Global scientific efforts (GO-SHIP, SOCAT, GCOS) which host and feature data from various ocean observing efforts and/or focus on collecting measurements in international waters will also be queried for annual or more likely multi-year data sets representing status and change of ocean acidification variables in the open ocean.

The data collection process takes place in close collaboration with the IOC Project Office for IODE Oostende, Belgium and relevant data providers/national archives, the GOA-ON data portal, and entities such as the marine chemistry part of the European Marine Observation and Data Network (EMODnet). Since 2019 IOC invites all data providers to use the newly established SDG 14.3.1 Data Portal (http://oa.iode.org). This 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 Sustainable Development Goal 14.3.1 Indicator: Average marine acidity (pH) measured at agreed suite of representative sampling stations. Besides allowing for a direct submission of metadata and data, the portal further provides the full text of the SDG 14.3.1 Indicator Methodology, the data template, the metadata template and the metadata instructions file. Since 2020 a newly developed FAQ section facilitates the provision of 14.3.1 data. IOC is developing a federated data system to automatically harvest data from other relevant ocean carbon databases and repositories into the SDG 14.3.1 Indicator database.

Furthermore the GOA-ON data portal features open access data, in addition to a global monitoring asset inventory. The portal is designed to offer two levels of access: 1) visualization and 2) download capabilities. Combining different open-access data sets may provide incentives to create new observing systems in under-sampled areas and to increase the application of open access data policies worldwide, according to the IOC Criteria and Guidelines for the Transfer of Marine Technology (2005) in the future.

Furthermore, the GOA-ON website hosts a number of pages dedicated to the SDG 14.3.1 methodology: http://goa-on.org/sdg_14.3.1/sdg_14.3.1.php.
