Summary: | Polar lakes are remote and in climatically challenging envi-ronments. As such, they impose major logistic constraints in terms of data acquisition. In many cases they can only be accessed during summer. From a scientific perspective, they are important because they are in latitudes that are experienc-ing the greatest effects of global warming. However, there are regional and short-term temporal differences in climate change. For example, there are warming trends across parts of the Arctic whereas other areas are cooling (Chapman and Walsh 1993). In Antarctica, the McMurdo Dry Valleys have been the focus of considerable climate study (Doran et al. 2002). There is clear evidence of recent warming that has resulted in increased water levels in the lakes (Webster et al. 1996; Lyons et al. 1997). However, more recent data suggest a phase of cooling in the Dry Valleys, which has impacted pri- |
