Sharks, Subsea Cables, and EMF: What Ocean Science Reveals About Electromagnetic Fields

A new study found that small-spotted catsharks exposed to electromagnetic fields from subsea power cables showed a twenty-five percent reduction in transit time during direct current field exposure -- a subtle but measurable behavioral shift in animals that rely on electromagnetic sensing for survival. In this episode, I break down what a two thousand twenty-five marine biology study tells us about how living organisms respond to artificial electromagnetic fields in their environment. We look at what the researchers found, why elasmobranchs make such a revealing test subject, and what this kind of science means for how we think about EMF and biology more broadly. In This Episode Why sharks are uniquely sensitive to electromagnetic fields -- and what that sensitivity reveals What researchers found when catsharks were exposed to field-relevant EMF levels from subsea power cables How Hidden Markov Models helped detect behavioral shifts that standard observation would miss Featured Study Read the full study: From subsea power cable to small-spotted catshark Scyliorhinus canicula: Behavioural effects of electromagnetic fields in tank experiments See all studies at shieldyourbody.com/research
