Dissolved oxygen in the water column is a primary input into the calculation of metabolism and respiration (refer Metabolism BASE Model dataset). Data loggers are deployed at multiple locations in the rivers of each of the Flow-MER Area-scale project to measure continuously at 10 minute intervals:
The data record aims to be continuous over the summer water management period, however there are breaks in the data record due to high water levels preventing data retrieval and equipment losses. There is generally at least one data logger deployed near locations where fish are also sampled.
The CEWH’s Flow-MER program examines the contribution of Commonwealth environmental water to the environmental objectives of the Basin Plan 2012 (Basin Plan) and is assisting the CEWH to demonstrate environmental outcomes and adaptively manage the water holdings. Monitoring and evaluation is focused in seven Selected Areas: the Junction of the Warrego and Darling rivers, Gwydir river system, Lachlan river system, Murrumbidgee river system, Edward/Kolety-Wakool river system, Goulburn River and Lower Murray River.
This Flow-MER data set includes and extends the long-term data collected at the same sites during the Long Term Intervention Monitoring (LTIM) project (2014-2019).
