Until now, measuring CO2 concentrations — a quantifier of ocean acidification — was mostly done from ships, buoys and moorings tethered to the ocean floor.
Researchers are using an underwater drone to measure carbon dioxide (CO2) levels in the ocean. It is believed to be the first time such a vehicle has been used to test CO2 levels.
