Global Through Local Scales

GOA-ON is organized at the global scale, reaching out to members all over the world who are working at local through global scales. Our mission is globally based for three important reasons:

  1. We need information and data products that can inform policy and the public with respect to ocean acidification and implications for the overall ecosystem health (status) of the planet.
  2. Ocean acidification processes are occurring at global scales; therefore, we need to go beyond local measurements and observe ocean acidification globally in order to understand its drivers correctly.
  3. Insufficient observations and understanding impede the development of robust predictive skills regarding ocean acidification and impacts. While we need enhanced coverage at local scales, successful international coordination of these observations will allow for nesting of these local observations within a global context.

High-level Goals

Goal 1: Improve our understanding of global OA conditions

  • Determine status and spatial / temporal patterns in carbon chemistry, assessing the generality of response to ocean acidification.
  • Document and evaluate variation in carbon chemistry to infer mechanisms (including biological) driving ocean acidification.
  • Quantify rates of change, trends, and identify areas of heightened vulnerability or resilience.

Goal 2: Improve our understanding of ecosystem response to OA

  • Track biological responses in concert with physical/chemical changes.
  • Quantify rates of change and identify locations and species of heightened vulnerability or resilience.

Goal 3: Acquire and exchange data and knowledge necessary to optimize modeling for OA and its impacts

  • Provide spatially and temporally resolved biogeochemical data for use in parameterizing and validating models, including societally-relevant forecasts and projections.

A Nested Approach

The three high-level goals for each geographic environment will be realized using a nested approach differentiating between:

  • Critical minimum measurements (Level 1)
  • Enhanced measurements to further the understanding of primary mechanisms (Level 2)
  • Opportunistic or experimental measurements (Level 3)
