From: Performance of an ultrasonic telemetry positioning system under varied environmental conditions
Time series of performance metrics and environmental variables for the riverine array. Measurements of (a, b) performance metrics and (c-e) environmental variables during the study period from 10 April to 12 June 2012. Inclusion of a diel factor did not explain important differences in positioning performance at this site so positions from both day and night periods are combined in (b). For data sources, see text.
