Unknown Impulse Detection Events Recorded at SanctSound Site HI01_02

Published by NOAA National Centers for Environmental Information | National Oceanic and Atmospheric Administration, Department of Commerce | Metadata Last Checked: April 12, 2026 | Last Modified: 2023-06-15T00:00:00.000+00:00
This record represents the unknown impulses 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 HI01_02 between December 01, 2019 and April 11, 2020.
