The NOAA ship Ron Brown is a major research platform for ocean and climate studies. This ship travels worldwide, participating in diverse measurements of the atmosphere and ocean. While the ship is underway, a hull-mounted Acoustic Doppler Current Profiler (ADCP) measures the velocity of the upper-ocean currents below the ship. On occasion, the Ron Brown is in the equatorial Pacific while maintaining the TAO buoy network. Some of the data shown are from the TAO mooring cruises (also shown in the Ka`imimoana page).

Links to vector and contour plots of the velocity data in gif and/or postscript format are provided below. Selecting "examine data" will access an image map of the cruise track. Selection of any of the labeled sections, by clicking on the letter, will show a vector plot of upper ocean velocities over topography, with temperatures color-coded on the vectors. Contour plots of both zonal and meridional velocity versus depth and the appropriate horizontal dimension are accessible from the vector plots. These plots display shaded velocity values between +/- 100 cm s^-1 typically, with divisions at +/- 10 cm s^-1. Positive and negative values are demarcated with a black line Cruises marked with "NODC" have been released to the NODC ADCP archive (JASADCP).
