Electromagnetic Signal Transmission From Aerial Sounds

---

This is a scientific mission to detect biologically-generated radio signals by monitoring the aerial exhalations of humpback whales from an isolated lighthouse in Alaska. The project investigates the "thrum," a low-frequency sound that researchers believe creates electromagnetic transmissions through the movement of charged aerosol droplets in the whale's spout. By correlating acoustic and radio data, the team aims to establish a new eco-centric paradigm for the Search for Extraterrestrial Intelligence (SETI), shifting the focus from purely technological markers to biological ones. Ultimately, the study seeks to refine the Drake Equation by demonstrating that intelligent life might evolve natural, rather than just mechanical, methods for long-distance communication across watery worlds.

Are we alone, or have we simply been tuned to the wrong frequency? The STRIDE project ("Detection, Characterization, and Implications of Radio Electromagnetic Signal Transmission from Aerial Sounds of the Humpback Whale") is a groundbreaking interdisciplinary initiative dedicated to establishing the first evidence of biologically generated radio transmissions. Led by Principal Investigator Isabel Gerrard and Co-Investigator Dr. Fred Sharpe, our team is investigating a radical hypothesis: that the humpback whale is an active speed-of-light communicator. Our research centers on the "thrum," a powerful, elephant-like aerial rumble that has remained largely overlooked by science for decades. We hypothesize that as a whale thrums, the oscillation of electrically charged aerosolized seawater droplets in its spout generates an electromagnetic (EM) signal in the Super Low Frequency (SLF) range (30–300 Hz). In this model, the vertical plume of the whale's blow acts as a biological vertical whip antenna, potentially broadcasting information across a medium we previously thought whales could not access.

By investigating biological pathways for radio communication, we are challenging the "anthropocentric shortfall"—the bias that intelligent signals must be technological. Our findings aim to:

• Redefine the Drake Equation: Informing terms to include intelligent life that evolves biology to communicate.
• Search for Life on Hycean Worlds: Providing a model for communication on remote, watery planets throughout the galaxy.
• Decode Universal Intelligence: Moving beyond searching for "perfect" technological spikes to recognize the distorted, environmentally entangled signals of the natural world.
