The Mariana Trench<\/strong>, Earth’s deepest ocean point, has long intrigued scientists with strange moans heard in its depths. First detected in 2014, these sounds baffled marine experts who initially thought they came from machinery or ships. Using AI nicknamed the “Whale Shazam<\/strong>,” scientists solved the mystery: the moans are from Bryde’s whales<\/strong> (Balaenoptera brydei<\/em>).<\/p>\n\n\n\n

The peculiar “Biotwang<\/strong>” sound\u2014low grumbling followed by metallic ringing\u2014was recorded acoustically near the Mariana Trench in 2014, sparking marine biologist curiosity. Despite efforts, its source remained unknown for years.<\/p>\n\n\n\n

The moan had a unique acoustic pattern unlike other known marine animals<\/a>. Initially mistaken for ship noise, confusion grew. “It was assumed to be a baleen whale, but without visual verification, species assignment was impossible,”<\/em> researchers noted.<\/p>\n\n\n\n

Lack of direct visual evidence hindered pinpointing which deep-sea creature produced such a distinctive abyssal sound.<\/p>\n\n\n\n

To crack the Mariana Trench enigma, scientists teamed with Google researchers developing artificial intelligence<\/strong> to identify whale vocalizations. Dubbed “Whale Shazam,” this AI analyzes vast acoustic datasets against known call patterns.<\/p>\n\n\n\n

Researchers matched Mariana Archipelago acoustic recordings and visual observations to identify the mysterious Biotwang<\/strong> with a specific whale species.<\/p>\n\n\n\n

AI confirmed Biotwang<\/strong> as Bryde’s whale vocalization\u2014a thrilling milestone revealing this species’ presence where population movements were poorly understood.<\/p>\n\n\n\n

Bryde’s whales remain poorly known, especially Pacific North migration\/distribution patterns. The study revealed seasonal Mariana Trench presence, plus western Pacific regions including Wake Islands and occasionally northwest Hawaiian Islands. This seasonal pattern correlates with low-to-mid latitude annual migrations.<\/p>\n\n\n\n

Authors noted Biotwangs<\/strong> increase February-April, peaking August-November, suggesting migration through this region. This data illuminates these wandering whales<\/strong>‘ movements and ocean interactions.<\/p>\n\n\n\n

Researchers conclude: “Our results provide evidence of a pelagic Bryde’s whale population in the northwest Pacific with broad distribution but seasonal\/interannual presence variations implying complex range likely linked to changing oceanographic conditions.”<\/em><\/p>\n\n\n\n

This significantly improves Bryde’s whale migration route understanding, opening climate\/ocean condition impact research.<\/p>\n\n\n\n

Mariana Trench mystery moans from Bryde’s whales mark exciting marine biology advance. AI resolved a decade-long enigma, revealing hidden whale populations.<\/strong><\/p>\n\n\n\n
