This instructional training video demonstrates how Eclipse Soundscapes (ES) Data Collectors set the internal clock on their AudioMoth device using the Time Chime feature prior to deployment. Accurate time configuration was a critical step in the Eclipse Soundscapes data collection protocol. Audio recordings needed to align precisely with eclipse phase timing, including annularity during the October 14, 2023 annular solar eclipse and totality during the April 8, 2024 total solar eclipse. Proper clock synchronization ensured that soundscape recordings collected across geographically distributed sites could be interpreted in relation to rapid changes in light conditions during eclipse maximum. Data Collectors were first instructed to verify whether the AudioMoth clock was correctly set (see related training video: ES Data Collector Training: How to Check to See if AudioMoth Clock is Set). If the clock required adjustment, this video demonstrates the step-by-step procedure for setting the Time Chime and synchronizing the device clock. Eclipse Soundscapes Data Collectors used AudioMoth devices to record full-spectrum environmental audio, known as soundscapes, for five consecutive days surrounding the 2023 and 2024 solar eclipses. Ensuring accurate time settings supported consistent, high-quality data collection across all recording locations. General Eclipse Soundscapes Project Information The Eclipse Soundscapes Project (ES) was a NASA Volunteer Science project funded by NASA Science Activation that studied how solar eclipses affect life on Earth during the October 14, 2023 annular solar eclipse and the April 8, 2024 total solar eclipse. ES revisited a historic study from the early 1900s showing that animals respond to eclipses and used modern technology and public participation to expand that research. Eclipse Soundscapes was an enterprise of ARISA Lab, LLC and was supported by NASA award No. 80NSSC21M0008.
