Downstream nutrient changes through the Mackenzie River Delta and Estuary, western Canadian Arctic
The effect of the large lake-rich delta and freshwater-saltwater transition zone (FSTZ) on nutrients from the Mackenzie River was investigated during open water of 2003-2004. Water volume storage in the Mackenzie Delta at peak levels was estimated by quantitatively partitioning the landscape (via GI...

The effect of the large lake-rich delta and freshwater-saltwater transition zone (FSTZ) on nutrients from the Mackenzie River was investigated during open water of 2003-2004.

A river and lake mixing model and biogeochemical sampling of upstream and downstream delta channels were used to estimate average nutrient composition of water outflow from the delta. Results showed that the delta was a sink for particulates and dissolved inorganic nutrients while dissolved organic matter was enhanced.
