SeapHOx sensor at Agua Hedionda Lagoon

Chief Scientist: Todd Martz Function: Measuring Ocean Acidification in the Field. The SeapHOx can measure not only the pH of seawater but other crucial parameters such as dissolved oxygen, temperature, and salinity. This data was collected from a SeapHOx sensor mounted on a mooring in the outer lagoon area of Agua Hedionda. Data collection started in 2019 and is ongoing.
