deep-sea anomalies
Ocean floor oddities
Deep-sea anomalies are unexplained phenomena or unusual findings in the ocean's depths—strange sonar readings, unidentified objects on the seafloor, or biological discoveries that defy expectations.
The term appears in oceanography, conspiracy theories, and science fiction alike: Researchers detected a deep-sea anomaly that didn't match any known geological formation.
The phrase evokes mystery, given how little of the ocean floor has been explored.
