A team of researchers is deploying a fleet of robotic ocean-monitoring floats across the world’s oceans to better understand and monitor their health. The Global Ocean Biogeochemistry Array (GO-BGC) project will use 500 robotic floats equipped with a range of sensors to collect data on the chemistry and biology of the ocean. The biochemical floats drift through the ocean and change depth at different intervals to collect data. We don’t monitor it very well,” Ken Johnson, GO-BGC project director and senior scientist at the Monterey Bay Aquarium Research Institute (MBARI), said, according to Reuters. The floats have been used in the Antarctic Ocean for years and the GO-BGC project just began deploying the devices in the western North Atlantic in March.
