^aComputed as the total number of valid data points obtained divided by the run time for each deployment multiplied by the sampling frequency (expected data).

^bRepresents the percent of expected runtime.

^cPercent of deployments resulting in >90% of expected runtime.

^dSampling frequency was variable during deployments (Median (IQR) seconds between data points = 480 (240–1560)).
