IODINE CYCLING IN THE SARGASSO SEA AND THE BERMUDA INSHORE WATERS Academic Article

abstract

• Methods have been developed for the measurement of iodate and total iodine in ocean waters based on the spectrophotometric method of Truesdale and Spencer (Mar. Chem., 2 (1974) 33-47). Total iodine is measured as iodate after photo-oxidation of reduced forms of iodine with UV light, and iodide is then calculated by difference. A complex interference from nitrate is reported and discussed. Measurements of iodine concentrations in the Sargasso Sea and the Bermuda inshore waters suggest a seasonal cycle. This seasonality appears to be the result of water masses becoming isolated by hydrographic effects for a sufficient time for iodate reduction to significantly change the iodate/total iodine ratio. The mechanisms for the reduction are at least partly biological, but other mechanisms may also play a part. 1988.
