MBARI engineers compete in third phase of XPRIZE competition
February 18, 2015
Last fall, MBARI hosted the first two phases of the Wendy Schmidt Ocean Health XPRIZE competition. The competition challenged teams to design robust pH sensors that could accurately and affordably measure ocean acidification. Eighteen teams participated in the first phase of the competition; 14 teams made it to phase three. The third phase took place earlier this month, when instruments that survived the first two phases were tested in challenging coastal conditions in Seattle, Washington. The instruments were placed in a test tank built near the Seattle Aquarium, with continuously pumped seawater from Puget Sound. The purpose of this phase was to test the instruments’ resistance to biofouling. Ken Johnson, a senior scientist at MBARI, and Hans Jannasch, a senior research specialist, are members of Team DuraFET, one of the teams that participated in the phase-three testing.
