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.

Research Shows Increasing Rate of Ocean Acidification

Often lost in the debate over climate change and CO2 emissions is the link between rising carbon dioxide levels and ocean chemistry. Since the early 19th century, scientists have understood carbon dioxide as a greenhouse gas. Late in the 19th century researchers began to suspect that CO2 emissions could alter climate. For at least the past three decades the link…
