Ocean acidification measurement competition
Five finalist teams have been selected to compete for the US$2m Wendy Schmidt Ocean Health XPRIZE, a global competition to create pH sensor technology to accurately measure ocean acidification.
On 14 May, the teams will board the research vessel R/V Kilo Moana for a week-long deep sea trial to assess ocean pH values at Station ALOHA in the Pacific Ocean.
During the six-day period, sensors will be put through rigorous performance tests focused on stability and precision, while battling real-world pressure scenarios and depths of up to 3,000m.
The five finalist teams representing four countries are: ANB Sensors (Cambridge, England), HpHS (Yokosuka, Japan), Sunburst Sensors (Missoula, Mont., US), Team Durafet (Plymouth, Minn., US) and Team XYLEM (Bergen, Norway/Beverly, Mass., US).
To reach this point, teams had to successfully put their sensors through a three-month test in controlled laboratory conditions at the Monterey Bay Aquarium Research Institute, then a month-long performance test in a coastal environment at the Seattle Aquarium.
The teams are competing for two available prizes - the US $1m accuracy purse, based on performance, and the US$1m affordability purse, based on cost and usability.
Winners will be announced in July 2015.
