SDG 14.3.1. Indicator Methodology - Ocean Acidification Data Survey
As part of the Agenda 2030 a total of 17 Sustainable Development Goals were developed, each with a particular focus and target. Sustainable Development Goal (SDG) 14 is focused on ‘Life below water’ and calls to "conserve and sustainably use the oceans, seas and marine resources for sustainable development." The SDG 14 Target 3 addresses Ocean Acidification, it reads as follows ‘Minimize and address the impacts of ocean acidification, including through enhanced scientific cooperation at all levels’. The Intergovernmental Oceanographic Commission of UNESCO (IOC-UNESCO) is custodian agency for its indicator 14.3.1, which is used to measure the progress made to achieve the target. Together with experts in the field of ocean acidification, in particular with the support from GOA-ON, IOC-UNESCO has developed the SDG Indicator 14.3.1 Methodology ‘average marine acidity (pH) measured at agreed suite of representative sampling stations’. The Methodology provides the necessary guidance on which variables to report, how to conduct ocean acidification measurements and on how to report the collected information in a transparent and traceable manner.
Your answers to this survey will help trace where ocean acidification data is being collected, and where it is stored and served, to facilitate reporting towards the SDG Indicator.

Thank you very much for taking 5 minutes to fill in the survey. Please note that the deadline for the survey is 20th December 2018.

Do you/your laboratory collect data of ocean acidification variables (at least one of the following: pH, total dissolved inorganic carbon (DIC), total Alkalinity (TA), pCO2/fCO2)?
If you collect data of ocean acidification, do you also submit these data to a data centre?

Your answer
If you replied yes - Are data usually submitted in a delayed mode or near real time?
How frequently are data uploaded in a delayed mode?
Which type of ocean acidification data do you submit?
Do you collect the corresponding metadata, e.g. applied methodologies, calibration frequency, date and time, place and depth?
If you answered yes, do you also submit these metadata to a data centre?
