Ocean Acidification is silently threatening the world’s waterways from coastlines to the deep sea. As humans release more CO2 into the atmosphere, scientists are racing to monitor and protect the world’s ocean species, but without accurate, reliable, and affordable pH sensors the task is difficult.

The Wendy Schmidt Ocean Health XPRIZE has challenged teams of “engineers, scientists, and innovators from all over the world to create pH sensor technology that will affordably, accurately and efficiently measure ocean chemistry from its shallowest waters… to its deepest depths.”  

Join Philippe Cousteau as he engages in a conversation with semi-finalists, Team SEAS, competing to create pH sensor technology that will allow the world to better understand the global state of ocean acidification. Live from the Seattle Aquarium, these teams of engineers will discuss their design process and share their knowledge of ocean acidification and engineering practices with students from across the globe.

This hangout will focus on the following Next Generation Science Standards for High School students:

• Develop a quantitative model to describe the cycling of carbon among the hydrosphere, atmosphere, geosphere, and biosphere. (HS-ESS2-6)
• Analyze a major global challenge to specify qualitative and quantitative criteria and constraints for solutions that account for societal needs and wants. (HS-ETS1-1)
• Design a solution to a complex real-world problem by breaking it down into smaller, more manageable problems that can be solved through engineering. (HS-ETS1-2)
• Evaluate a solution to a complex real-world problem based on prioritized criteria and trade-offs that account for a range of constraints, including cost, safety, reliability, and aesthetics as well as possible social, cultural, and environmental impacts. (HS-ETS1-3)
• Use a computer simulation to model the impact of proposed solutions to a complex real-world problem with numerous criteria and constraints on interactions within and between systems relevant to the problem. (HS-ETS1-4)
