This dataset contains Turbulent Point Water Velocity (VELPTTU) data from a Nobska - MAVS-4 3-D Single Point Velocity Meter (VEL3D) on the Axial Base Seafloor (RS03AXBS) Medium-Power JBox (MJ03A) at 2,642m depth as part of the Cabled Axial Seamount Array for 2014-08-21 to 2025-07-20. Axial Base Seafloor (RS03AXBS) is supported by the Axial Base Primary Node (PN03A). These data were last updated by OOI on 2025-07-20 and were received by NCEI on 2025-07-20.

The Ocean Observatories Initiative (OOI) is a network of interactive, globally distributed sensors that provides access to real-time ocean data, enhancing our capability to address critical issues such as climate change, ecosystem variability, ocean acidification, and carbon cycling. The Observatory consists of five arrays continuously collecting ocean data. Two coastal arrays expand existing observations off both U.S. coasts. A cabled array wires a region in the Northeast Pacific Ocean with high-speed optical and high-power grid that powers data gathering and observation. Global components address planetary-scale changes using moored open-ocean infrastructure linked to shore via satellite.
