Katsuko Saruhashi developed, in 1955, a set of tables still known as Saruhashi's Table for calculating dissolved carbon dioxide in seawater from its temperature, pH, and salinity, a tool oceanographers still use. Working with Yasuo Miyake she measured radioactive fallout, caesium-137 and strontium-90, in Pacific seawater after nuclear weapons testing and found levels far higher in the western Pacific than the Atlantic, evidence that helped support the case for a ban on above ground nuclear tests.

Katsuko Saruhashi (猿橋 勝子, Saruhashi Katsuko; March 22, 1920, September 29, 2007) was a Japanese geochemist who created tools that let her take some of the first measurements of carbon dioxide (CO2) levels in seawater.
