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.
