Areas of Uncertainty for vocalizing marine mammals in the Chukchi Sea, August through December 2011
We generated extremely reliable 100% Confidence Intervals of Location (CIL) for calling mammals in the Chukchi Sea. Data come from archival recordings of NOAA's CHAOZ experiment from two pentagonal acoustic arrays in shallow water between August through September 2011. CIL are generated with ma...
