The R/V Nathaniel B. Palmer 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.

Links to vector and contour plots of the velocity data in gif and/or postscript format are provided below. Selecting "download data" will send the user to the official publically-accessible data archive. 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. Plotted temperatures come from the transducer well, and are hence only very approximate. 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.

NOTE: If you experience difficulty choosing a particular section, try going to the section list (from any vector or contour plot) and loading from there.
