Data availability

Refer to the Data Availability statement in the paper for links to requisite data, including:

• Navy acoustic data from the NAVFAC database, exported from Larson Davis binary in xlsx format in the same directories as the original binary files.
• NPS acoustic data from the National Park Service Night Skies and Sounds Division, in txt format.
• JGL acoustic data from JGL Acoustics, Inc. in csv format.

Software and package dependencies are listed in methods.Rmd.

Contents

The full data processing and analysis pipeline described in the "Materials and Methods" section of the paper can be found at methods.Rmd. global.R contains global variables, functions, and settings used throughout the repository. See sections below corresponding to repository directories.
