Deep Ocean Argo Floats, New Approach Yield New Insights into Ocean Acidification

Thanks to the National Oceanic & Atmospheric Administration and a joint US-Canadian research team, it is now possible for marine scientists to use satellite data from five-foot-tall Argo floats that drift with deep ocean currents to remotely monitor ocean acidity (pH) and the total carbon dioxide (CO2) content of seawater to better understand changes in ocean chemistry.
