Argo floats help monitor ocean acidity

Scientists can now remotely monitor the ocean’s changing chemistry with help from some of the five-foot-tall Argo floats that drift with deep ocean currents and transmit data via satellite back to land. A new and innovative method shows how readings of the acidity (pH) and total carbon dioxide (CO2) content of seawater can help scientists understand changes in the chemistry of the world’s ocean.
