Water Circulation and Marine Environment in the Antarctic Traced by Speciation of 129I and 127I

open access: yesScientific Reports, 2017
Emissions of anthropogenic 129I from human nuclear activities are now detected in the surface water of the Antarctic seas. Surface seawater samples from the Drake Passage, Bellingshausen, Amundsen, and Ross Seas were analyzed for total 129I and 127I, as ...
