The Wendy Schmidt Ocean Health XPRIZE is a $2 million global competition that challenges 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 water to its deepest depths. On July 20, 2015, the winners of the competition will be announced in an exciting and jaw-dropping ceremony at the Harold Pratt mansion. Tickets to this exclusive event are invitation only, but livestream will be available on this page on the day of the event.
