Extract

A method, suitable for routine use, of determining total iron in sea water is described. The water is acidified to about o·13N with hydrochloric acid and is heated for 5 h in an autoclave at 140°C. Iron is determined absorptiometrically with 1:1 phenanthroline after reduction with hydroxylamine hydrochloride.

Tests of the method, collection and storage of samples and the variability of results are described.

Iron contents of water samples from the English Channel and the Bay of Biscay are reported.
