The present work constitutes the first survey of iodine isotope ratios for Scottish seawater, including the first data for the west of Scotland. I/I ratios in the south-west Scotland reached 310 in 2004. Iodine isotope ratios increased by about a factor of 6 from 1992 to 2003 in the north-east of Scotland, in agreement with the increase of liquid I emissions from Sellafield over that time period.
