Explosion Detection Events Recorded at SanctSound Site MB03_03

Metadata Updated: June 16, 2023

This record represents the explosions detected from raw passive acoustic data. All acoustic data were processed using Triton's Explosion Detector, which is based on a cross-correlation of the recording with a template explosion. The detector divides the recording into sequentially analyzed sections of 75 s. The detector outputs are a series of .mat files that can be evaluated using GPLReview. The original wav file was decimated to a sample rate of 12 kHz, a requirement of the algorithm. The default parameters work well for most explosive sounds. These data were recorded at SanctSound Site MB03_03 between April 11, 2020 and September 21, 2020.
