Radium Isotope Study of the Circulation in the Second Branch of the Tsushima Warm Current

A research team including Oki Marine Biological Station, a member of JAMBIO, presented their joint research on ocean dynamics in the Japan Sea.

The second branch of the Tsushima Warm Current was discussed by examining the surface distribution of radium isotopes in the surface seawater of the southwest region of the Japan Sea and their seasonal variations.

Furthermore, the results provide a good explanation for the influx of dissolved contaminants (very low concentrations of radiocesium) into the Japan Sea.
