Deep, strong ocean currents circle the globe in the Southern Ocean. This influential flow, known as the Antarctic Circumpolar Current, connects all three major oceans. Its narrowest constriction is Drake Passage, a location notorious for its challenging seas. Despite the difficulty, Drake Passage has seen several enduring studies by U.S., U.K. and French researchers. For two decades, ADCPs carried by U.S. Antarctic supply ships have continually measured currents during crossings of Drake Passage.

To learn how these ADCPs have performed in research performed on ice breakers, read the case study from Teledyne Marine: Two Decades of Southern (Ocean) Rock ‘n Roll.
