Acoustic behavior of endangered Hawaiian false killer whales

This dataset accompanies the study: Acoustic behavior of endangered Main Hawaiian Islands insular false killer whales *(Pseudorca crassidens) *and contains data and analyses used to characterize the pulsed call repertoire, nonlinear phenomena, and behavioral context of calling. Biologging tags (CATS and DTAG) were deployed on four individuals from two social clusters around the Main Hawaiian Islands between 2011 and 2024. The CATS tags were sampled at 96 kHz, and the DTAG at 240 kHz. Data was processed using Raven Pro and PAMGuard.
The repository includes the following:

Data inputs (kinematic/acoustic data tables)
Data used in the statistical analysis
Interobserver reliability test scores
Spreadsheets of call features from each trace extracted using the ROCCA module in PAMGuard for each call type
Examples of audio files used to generate spectrograms in the Supplementary material (S1)

A total of 5,940 high-quality possible focal pulsed calls were analyzed, from which 52 stereotype..., , # Data from: Acoustic behavior of endangered Hawaiian false killer whales

## Description of the data and file structure

Two suction cup tag types were used to collect acoustic and kinematic data: digital acoustic recording tags (DTAG version 3) and customized animal tracking solutions (CATS) tags . Both tags were equipped with acoustic sensors to record sound production, a pressure sensor to record depth, and a suite of inertial sensors to measure animal orientation and allow for fine-scale movement tracking. Tags were deployed by pole during multiple boat-based field efforts in 2011 (off Hawaiʻi Island) and from 2023-2024 (off the islands of Maui and Lānaʻi). HTI-96 mini hydrophones (sampling rate 96 kHz, 16 bit resolution, flat frequency response from 2 Hz – 30 kHz) were integrated in the CATS tags with a hydrophone-specific sensitivity ranging from -169.4 to 170.2 re: 1V uPa-1. CATS tags were equipped with multiple inertial sensors including t...,
