This dataset provides ocean current velocities and directions that were quantified using a hull-mounted Teledyne RDI 75 KHz ADCP in December 2014 for the Submarine Ring of Fire – Ironman field effort aboard the R/V Roger Revelle. ADCP data were collected, processed, and analyzed using the University of Hawaii data acquisition system (UHDAS) [Firing and Hummon, 2010; Firing et al., 2012]. The ADCP was operated in narrowband mode, producing current profiles that typically reached 625 m and were processed to five minute averages and 16 m depth bins. Data are in netcdf format.
