  1. Tag mooring depth, offset that links tag measured total magnetic field values to mapped value at mooring location, range of detailed (4-min resolution) total magnetic field measurements, standard deviation of total magnetic field daily means, median difference between daily means and mapped value, Wilcoxon rank sums p-value for detecting bias, mean absolute error (MAE) between mooring and estimated locations from hidden Markov model (HMM), and mean size of daily error estimates from HMM. No HMM results were available for tag SO-2 because values measured were outside of the range of values in the study area
