Spatial variability of benthic diatom communities in the Windmill Islands, Antarctica.
Progress Code: completed A hierarchical, 3-level, nested design was used. The highest hierarchical level consisted of six locations. Two of these locations, Brown Bay and Shannon Bay, have been contaminated with heavy metals (Stark et al., 2003; Snape et al., 2001); Brown Bay has also been contamina...

The highest hierarchical level consisted of six locations.
