Uncharted Current Discovered in the South Pacific
A previously unknown deep-ocean current has been detected moving beneath the Pacific basin, challenging decades of accepted oceanographic models. The current, tentatively named the Bada Stream, flows at a depth of 4,000 meters and spans an estimated 2,300 nautical miles from the Mariana Ridge to the Chilean coast.
Marine scientists aboard the research vessel Cormorant made the discovery during routine sonar mapping. The current moves at an unprecedented 0.8 knots at depth, carrying cold water from the western Pacific toward South American shores. Implications for global climate models are being assessed by an international panel of oceanographers convened at the Bada Maritime Institute.
Early measurements suggest the Bada Stream transports approximately 15 sverdrups of water, placing it among the ten largest ocean currents by volume. Researchers believe the current may have existed for centuries, masked by the overlying South Equatorial Current.
