Abstract
The relationship between surface sediment diatom assemblages and measu red limnological variables in 33 coastal Antarctic lakes was examined by constructing a diatom-water chemistry dataset. Canonical correspond ence analysis revealed that salinity and silicate each explain signifi cant amounts of variation in the distribution and abundance of the sur face sediment diatom taxa. Salinity has the strongest influence, revea ling its value for limnological inference models in this coastal Antar ctic region.
