Description

Streambed oxygen demand (SOD) is thought to account for a significant fraction of the total oxygen demand in the Athabasca River in the winter. SOD was sampled in the Athabasca River from October 1994 to March 1995 with objectives of obtaining a series of measurements from upstream of Hinton to the Calling River area, and investigation temporal change in SOD at key sites.

Description

Sediment Oxygen Demand (SOD) is an important variable in the oxygen balance of rivers, in particular during the winter under low flow and extensive ice-cover. In 1989, a method to measure SOD in-situ was developed and used to measure winter SOD rates in the Athabasca River. The main objectives of the 1990 study were to determine if SOD rates increased over the winter and to determine the longitudinal trend of SOD in the Athabasca River and the Wapiti-Smoky River system.
