Dolphin Vocalization & Acoustic Research

A science-driven initiative to understand how dolphins use sound, and how a changing ocean is altering what they hear.

§ 01Focus

Two areas, one picture

01

Dolphin communication

Vocal patterns, frequency ranges and behavioral context in wild populations.

02

Marine soundscapes

Background ocean noise, natural and human-generated, and its environmental impacts.

§ 02Rationale

Dolphins live by sound

Dolphins depend on sound for navigation, foraging and social interaction. Rising vessel traffic, coastal development and environmental pressures are adding new, persistent noise to their habitat.

  • Identify patterns in vocal behavior
  • Assess human-generated noise impacts
  • Support habitat evaluation and site selection
  • Contribute to long-term ocean-health monitoring

§ 03Methodology

Non-invasive and field-based

All data collection follows ethical wildlife observation standards.

01

Passive acoustic monitoring

Hydrophones capture sound without disturbing animals.

02

Environmental data

Temperature, salinity and pH.

03

Habitat tracking

Weather and habitat condition records.

04

Comparative analysis

Across locations and time periods.

05

Broader soundscape

Including fish, shrimp and vessel noise.

06

Mobile field approach

Flexible deployment across multiple coastal environments.

§ 04Status

Equipment acquisition & preparation

01

Finalize equipment setup In progress

Research equipment configuration.

02

Prepare for field deployment

Calibration and readiness.

03

Plan initial locations

Choosing first data-collection sites.

Field data collection begins after equipment calibration and deployment readiness.
