Driving Question:
How might I develop my understanding of Marine communication through the use of coding as well as bioacoustics in the form of a fully functional communication device ?
The Project: Marine Communication & Bioacoustics Exploration
In response to the driving question, Liam F. developed a year-long mastery project titled “Whale Talk,” combining marine biology, bioacoustics, and technology. The project explored how marine mammals communicate and how humans might interpret these signals through innovative technological design. Through a combination of fieldwork, experimentation, and technical development, Liam investigated the intersection of science, engineering, and environmental curiosity.
The Design Goal
Working from a self-defined vision, the student aimed to design and develop a functional hydrophone-based communication system capable of recording, processing, and interpreting underwater sound.
Creative Direction:
The project blended scientific research with technological innovation, integrating marine biology concepts with coding, electronics, and device design.
Production Process:
Liam iteratively developed his device across multiple terms and locations, progressing from early research and field data collection to building, coding, and assembling a functional prototype. This included learning soldering, waterproofing, and Raspberry Pi integration.
Final Outputs:
The final project resulted in a custom-built hydrophone system connected to a Raspberry Pi, incorporating a speaker system, camera integration, and coded input/output features. The project was supported by a comprehensive process portfolio documenting research, development, and experimentation.

Innovation & Ethics
The project explored how innovation in technology can deepen our understanding of the natural world:
Scientific Exploration:
Research into marine mammal communication highlighted the complexity of underwater ecosystems and the potential of bioacoustics as a tool for discovery.
Technological Innovation:
The development of a self-designed hydrophone system required creative problem-solving, including overcoming challenges related to waterproofing, power supply, and device integration.
Ethical Awareness:
Field research emphasized responsible data collection and respect for marine environments, reinforcing the importance of protecting ocean ecosystems while conducting scientific inquiry.
Final Product: A Bioacoustic Communication System
The Assessment:
A fully developed prototype of a hydrophone-based communication device, supported by a detailed process portfolio documenting research, coding, and engineering development.
Academic Component:
An integration of marine biology research, coding practice, and applied engineering, demonstrating interdisciplinary learning across science and technology.
The Summative Reflection:
The student reflected on the complexity of building a functional communication device without an existing blueprint, emphasizing creativity, persistence, and adaptability. While the device is still evolving in functionality, the project exceeded initial expectations in both scope and progress. Liam expressed a strong commitment to continuing this work in the future, with the long-term goal of better understanding and potentially communicating with marine life.
