Fin Whale Sound Production Recorded at SanctSound Site SB01_06
This record represents fin whale sound production detected from raw passive acoustic
data. The Low Frequency Detection and Classification System (LFDCS) call library for
fin whale 20-Hz pulses was built for the data sampled at 120 Hz. All fin whale detections
with a Mahalanobis distance of 3.0 or less were manually verified for true detections.
A logistic regression was applied to these results to facilitate reducing the size
of the dataset that ultimately needed to be manually verified for confident species
detection. This analysis revealed that a minimum number of 29 detections per time
window used (hour or day) need to be detected to ensure that a fin whale was truly
detected with a confidence of 90%. All days with at least 29 detections were manually
verified for daily presence of fin whale 20-Hz pulses. From days with 29 or more detections,
fin whales were considered present for that day if a true detection was found within
a regular inter-pulse interval pattern of at least three other 20-Hz pulses. These
data were recorded at SanctSound Site SB01_06 between October 05, 2019 and December
06, 2019.
