Paid a $2 million purse to teams building affordable, accurate ocean pH and CO2 sensors.

Between cyclesXPRIZE FoundationGlobal

Launched in 2013 with a $2 million purse, this now-concluded prize asked innovators to build affordable, accurate and durable pH and carbon-dioxide sensors able to operate in real-world ocean conditions, from the surface down to the deep sea. Fifteen teams from the United States, United Kingdom, China, France, Japan and Austria entered, and finalist testing ran across three sites: the Seattle Aqua

Sought low-cost, robust sensors able to measure pH and carbon dioxide in seawater in real time, from surface waters down to the deep sea, under real-world lab and field conditions. The goal was global, consistent ocean-acidification monitoring to inform climate and marine-ecosystem research.
