DATA & FILE OVERVIEW

1. File List: 
mb17_224a_depth.nc   (individual 1 diving depth data at 1 Hz)
mb18_219a_depth.nc   (individual 2 diving depth data at 1 Hz) 
mb17_224a_echolocation.txt (individual 1 timing of echolocation signal production)
mb17_219a_echolocation.txt (individual 2 timing of echolocation signal production)

2. Relationship between files, if important: 
depth and echolocation data are associated in time, the .nc and .txt files match data for individual 1 (mb17_224a) and individual 2 (mb18_219a), respectively


METHODOLOGICAL INFORMATION

1. Description of methods used for collection/generation of data: 
Data was collected using Dtags, v4. https://www.soundtags.org/

2. Methods for processing the data: 
Described in the Methods Section. Scripts for data analysis available from: https://www.soundtags.org/

3. Instrument- or software-specific information needed to interpret the data: 
.nc files can be opened in Matlab.inc, using the command: load_nc
