This dataset is compiled from The City of Calgary’s in situ (in location) water quality monitoring program. In situ field measurements are acquired from the deployment of multi-parameter sondes in surface waters by The City of Calgary. Measurements are collected using two methods: Continuous and Discrete.
Continuous: In situ measurements logged at regular intervals (e.g. 15 minutes) for an extended period of time.
Discrete: Individual in situ measurements manually collected by a field technician.
Parameters that are measured include, but are not limited to: dissolved oxygen, water temperature, pH, turbidity, and specific conductance. Monitoring locations, intervals, and water quality parameters vary per site and period, depending on the monitoring objectives at the time of deployment. Multi-parameter sondes are routinely calibrated as per manufacturer’s specifications and verified against independent standards.
This data is not a live data feed. It is manually retrieved, reviewed, and posted at regular intervals. Field data is not altered or adjusted, though any data that is determined to be invalid based on sensor interference, sensor failure, or damage, has been removed from the final dataset.
Monitoring records are reported in the local time zone at the time of measurement for Calgary, Alberta (MDT/MST).
