Long-term Environmental Monitoring in Arctic Lakes and Ponds Using Diatoms and Other Biological Indicators

Long-term monitoring data are required to make effective environmental decisions. Unfortunately, such direct measurements are rarely available. Long-term data are especially sparse in arctic tundra regions, where logistic concerns often preclude the implementation of standard monitoring programs. Ho...
