$1 million X PRIZE : Measuring ocean acidification

The X PRIZE Foundation new prize Wendy Schmidt Ocean Health X PRIZE is offering “$1 million to the team that invents the most accurate sensors as well as another $1 million to the team that devises the most affordable and easy-to-use sensors.”

The sensor’s technical goals are threefold: to operate at depths of at least 3,000 meters, take measurements that are precise to the level of the annual pH change (roughly 0.002 on an acid-to-base scale that stretches from 0 to 14) and avoid the need for frequent recalibration. In addition, the sensors should be cheap so that they can be used widely.
