Abstract

The Bothnian Sea which is located between Finland and Sweden represents an important source of fresh water to the Baltic Sea. We here present new data on the radioactive isotope ¹²⁹I species from water samples collected in December 2009 at different depths in the Bothnian Sea. Concentrations of ¹²⁹I^- (iodide) in the Bothnian Sea range from 14 × 10⁸ to 32 × 10⁸ atoms/L, while ¹²⁹IO ₃ ^- (iodate) concentrations are relatively low and fluctuating at 1 × 10⁸ atoms/L. For nutrients data determined in the same samples as ¹²⁹I, significant correlations could be found between ¹²⁹I^- and total P, NO₃-N, SiO ₃-Si, but rather poor with NH₄-N. The correlations suggest comparable source pathway of ¹²⁹I^- and nutrient parameters, while the source of NH₄-N may be different. The small amounts and negligible change of ¹²⁹IO₃ ^- indicate prevailing extensive reduction of iodate in the Baltic Sea.
