The Global Ocean Acidification Observing Network (GOA-ON) is a collaborative international approach to document the status and progress of ocean acidification in open-ocean, coastal, and estuarine environments, to understand the drivers and impacts of ocean acidification on marine ecosystems, and to provide spatially and temporally resolved biogeochemical data necessary to optimize modeling for ocean acidification.

Dr. Chris Sabine of NOAA/PMEL tests an OA Starter Kit for a training workshop in Mauritius. This work is in support of the OA-Africa network and the GOA-ON Pier2Peer program.

The 3rd Annual GOA-ON Science Workshop, held in Hobart Australia, was attended by 130 scientists from 37 nations. Click here for a description of this successful workshop.

356 Scientists from 66 countries are currently participating.

GOA-ON releases a new Data Portal (September 2016)

The GOA-ON Interactive map has a new format and many new features, including:

  • the ability to find platforms based on regions, platform type, and variables;
  • overlays of aragonite saturation state and surface CO2 concentration;
  • real-time display of data from participating platforms;
  • and much more!

Mouse over the buttons below to see examples of the new functionality.

Building on the existing global oceanic carbon observatory network of repeat hydrographic surveys, time-series stations, floats and glider observations, and volunteer observing ships, the interactive GOA-ON map offers the best information available on the current inventory of global OA observing platforms. This is a strong foundation of observations of the carbonate chemistry needed to understand chemical changes resulting from ocean acidification.

Note to participants and contributors: If you would like to add or modify a platform, please fill out this on-line form: GOA-ON Survey
