Global OA Observing Network

Designing GOA-ON
Three international workshops, 2012-2103, defined theframework for the observation network– Rationale– Goals– Design– Suite of measurement parameters– Regional coverage (hubs)– Data quality and data distribution strategies– International program integration

GOA-ON plan:
www.goa-on.org
Goal 1: Detect ocean acidification
Goal 2: Ecosystem impacts
Goal 3: Data exchange and improvepredictions of change andimpacts

• GOA-ON observations have a nested design:
Level 1: critical minimum measurements
Level 2: measurements for integrated
assessment to enhance interpretation
Level 3: measurements that are not yet fully
ready for standardisation, in development orevaluation• Ecosystem variables will only be measured ina subset of total OA observation stations

Pier2Peer: mentorshipA mentorship program to expand ocean acidification observing
capacity through two-way sharing and capacity building activities.

International Professional Engagement: Mentors answer scientific questions andassist in professional development opportunities.
One-on-One Training: Competitive funding opportunities will be made available
for travel and training between P2P partners.
Strengthening GOA-ON: Members become a part of the GOA-ON Network.
