From: Performance of an ultrasonic telemetry positioning system under varied environmental conditions
Time series of performance metrics and environmental variables for the coastal array. Measurements of (a, b) performance metrics and (c-g) environmental variables during the study period from 24 September to 27 November 2009. The yellow line in (b) shows the daily mean positioning errors during the daytime period (7:00 to 19:00), while the grey line shows the daily mean positioning errors during the night period (19:00 to 7:00).
