Ten samples of freshwater from Campbell Island were analysed for their main ionic constituents. All show a preponderance of sodium and chloride derived from sea water. Potassium, calcium, and magnesium gave slightly higher concentrations than would be expected if derived solely from sea water. It is con‐eluded that the excess potassium is derived from the underlying rocks and soil, and the excess calcium and magnesium from the sea by fractionation into salt particles.
