Area of Science:

  • Marine acoustics
  • Seagrass ecology
  • Biophysics

Background:

  • Seagrass acoustic properties are influenced by density, gas content, and photosynthetic byproducts.
  • Existing predictive models for seagrass acoustics are lacking for applications like sonar and mine hunting.

Purpose of the Study:

  • To investigate the acoustic properties of three common seagrass species under laboratory conditions.
  • To assess the influence of biomass and gas content on sound speed in seagrass.
  • To evaluate the applicability of existing acoustic models for seagrass.

Main Methods:

  • Low frequency (0.5-2.5 kHz) acoustic laboratory experiments using a one-dimensional acoustic resonator.
  • Analysis of Thalassia testudinum, Syringodium filiforme, and Halodule wrightii.

  • Biomass and gas content estimation via microscopic cross-section imagery.
  • Comparison of experimental results with Wood's equation model predictions.

    • Main Results:

    • Effective sound speed in seagrass was significantly influenced by plant biomass.
    • Wood's equation, based solely on gas content, failed to predict sound speed under low irradiance (no free bubbles).
    • Findings align with previous in situ studies on other seagrass species.

    Conclusions:

    • Seagrass biomass is a critical factor in determining acoustic properties.
    • Current models based on gas content alone are insufficient for predicting seagrass acoustics, especially without photosynthesis-driven bubbles.
    • Further model development is needed for accurate acoustic remote sensing and sonar applications in seagrass habitats.
