We have measured Hg concentrations in one of the most remote aquatic systems in the world, Taylor Valley (∼78°S), Antarctica. These measurements, along with the previous work of Vandal et al. [ 1998 ], provide baseline concentrations of Hg, as well as an assessment of Hg speciation, in a remote aquatic environment. Dissolved Hg concentrations in the surface waters of these lakes and glacial streams range from 0.10 to 0.44 ngL −1 . These values are similar to those reported from other remote locations and suggest these values represent current baseline values globally.
