On Thursday, April 2nd, NOAA/PMEL Director Chris Sabine will discuss NOAA’s role in detecting ocean acidification and measuring community vulnerability to understand risk during Sound Conversations at the Seattle Aquarium. The Seattle Aquarium hosted the 3rd phase of the Wendy Schmidt Ocean Health XPRIZE aimed at developing affordable and accurate pH sensors. As a leader in ocean acidification research and detection, NOAA/PMEL scientists are providing validation measurements for the XPRIZE contest. By developing breakthrough ocean pH sensors, researchers, fisheries and resource managers, and environmental groups throughout the world will be able to measure ocean acidification in more places and with better resolution to increase the understanding of the risk ocean acidification poses to shellfish, coral reefs, and fisheries. This event is aimed at bringing the ocean acidification community together to learn about new innovative approaches to addressing ocean acidification from leaders in research, policy, and public engagement.
