Water Quality, Climate Change, and Lake Sediments: 
A Window on the Past and a View to the Future 
There is growing evidence that human activities are greatly impacting many 
ecosystems, although the timing and magnitude of changes are difficult to 
determine as long-term monitoring data are rarely available. Aquatic 
resources are considered to be especially at risk, but data on these 
systems are especially sparse. Important questions include: Is the water 
quality changing? If so, why and by how much? What are the causes of these 
changes? 
Because long-term monitoring data are not available, indirect methods must 
be used to infer past ecological conditions. Fortunately, aquatic systems 
archive a tremendously important library of information of past changes in 
their sediments. For example, a large number of organisms leave fossils in 
lake muds, which paleolimnologists can then use to track past environmental 
conditions. Important issues that have been addressed using these 
approaches include water quality deterioration (and recovery), climate 
change, and reconstructing past trends in important resources, such as fish 
stocks.
