CHANGES IN IODINE SPECIATION IN THE BENGUELA CURRENT UPWELLING SYSTEM Academic Article uri icon

abstract

  • Iodine speciation in the oxygen-depleted water mass along the west coast of South Africa was investigated in February 1979. The low oxygen water was related to the presence of a stable density layer with t = 26.8, which persists over long time periods. The remineralisation of the area is discussed in terms of the nutrient and iodine profiles and contrasted with deep-sea iodine regeneration. The presence of total iodine concentrations (dissolved and possibly particulate) of up to 6.6 M is probably accounted for by sediment release. Calculations of possible breakdown rates of phytoplankton suggest a continuous reduction process as the water body travels south, rather than a non-local source of the reduced waters. 1983.
