Nontoxic dye released from an artificial upwelling experiment off the Canary Islands. That experiment, set to last weeks, ended after just one day when the pump failed. “To most of us that proved … the technical readiness of this approach is not there,” says Michael Sswat, a postdoctoral researcher at GEOMAR Helmholtz Centre for Ocean Research, who was part of the research team.
