%description
Flux (mass per unit time) and Load (mass) are computed from timeseries
estimates of analyte concentration and discharge. Concentration timeseries
are computed from regression between surrogate and user-provided analyte.
Uncertainty in calculations is estimated using bootstrap resampling. Code
for the processing of acoustic backscatter from horizontally profiling
acoustic Doppler current profilers is provided. All methods detailed in
