Scripps Institution of Oceanography marine chemist Andrew Dickson plans to purchase and deploy an autonomous buoy-mounted sensor to study the effect increasingly acidic ocean water could be having on ecosystems in the California Current. Recently published findings by other researchers have indicated a disturbing upwelling of acidic waters into coastal regions that support sea urchins, abalone and other marine invertebrates whose ability to form shells could be impaired by the corrosive water. Dickson said recent discoveries like that underscore the need for more detailed measurements.
