    Abstract

    A complete transect of surface water samples from the North Sea to the Canary Islands was collected during a continuous period in 2010. The samples were analyzed for total 129I and 127I isotopes and their iodide and iodate species. The results indicate a large variability in the total 129I and its species along the transect, whereas less change and variation are observed for the total 127I and its species. Transport of 129I from the western English Channel via Biscay Bay is the main source of 129I in the northeastern Atlantic Ocean.
