Overview

Randomized trial observes spatiotemporal characteristics in underwater chorusing, suggesting acoustic influences.

Key Points

  • The research aims to model and understand the unusual patterns of underwater bioacoustic chorusing observed in Southern California.
  • Developed a stochastic numerical model based on excitable media physics.
  • Simulated calling animal behavior transitioning through states: excitable, active, and resting.
  • Analyzed the effects of sound levels and noise from a passing ship on chorus dynamics.
  • Simulations replicated night-long cycling levels and sunset chorusing patterns.
  • Model demonstrated periodic upcoast evolution mimicking 'The Wave' seen in stadiums.
  • Additive ship noise significantly altered spatiotemporal characteristics of the chorus.
