10 Sep 2013: New Prize is Created to
Improve Measurements of Ocean Acidity

Philanthropist Wendy Schmidt is offering $2 million in prize money to inventors who can develop inexpensive and easily deployable sensors to measure ocean acidification. The Wendy Schmidt Ocean Health X Prize is offering $1 million to the team that invents the most accurate sensors to measure the ocean’s acidity and $1 million to the team that devises the most affordable and easy-to-use sensors. Biologist Paul Bunje, a senior executive for oceans at the X-Prize Foundation, said that because current ocean acidity sensors can cost more than $5,000, very little is known about the pace of ocean acidification in various regions and depths. The goal, said Bunje, is to deploy many thousands of sensors worldwide. Rising concentrations of atmospheric carbon dioxide mean that more CO2 is being dissolved in the oceans, steadily making them more acidic. Schmidt, estranged wife of Google Executive Chairman Eric Schmidt, previously funded a successful prize contest to develop technology to better clean up oil spills.
