WOCE Indian Ocean Shipboard ADCP data
WOCE cruises in the Indian Ocean included data from a hull-mounted Acoustic Doppler Current Profiler (ADCP), which measures the velocity of the upper-ocean currents below the ship. Thermistor temperature and salinity were corrected using local CTD and onboard flowthrough system data.
Links to contour and vector plots of the velocity data in gif and postscript format are provided below. Selecting either gif or postscript format will access an image map of the cruise track with upper layer velocity vectors superimposed. Selection of any of the labeled sections (click on the letter) will show a vector plot of upper ocean velocities over topography, with temperatures color-coded on the vectors. (Colored vectors for each section are flanked by an additional region plotted in black for context). Contour plots of both zonal and meridional velocity versus depth and the appropriate horizontal dimension are accessible from the vector plot. The contour plots display shaded velocity values between +/- 100 cm s-1. Bold contours occur on 50 cm s-1 intervals and light contours occur on 10 cm s-1 intervals. One temperature rscale (-1.2 C to 21.3 C) was used for the two Southern Ocean cruises (kn9412 and np9603). The rest of the Indian Ocean cruises used a different temperature scale (7.5 C to 33.5 C).
NOTE: If you experience difficulty loading a particular section plot, (because the labels are packed too tightly), try going to the section list (from any vector or contour plot) and loading from there.
All plots were made in matlab: projections used in vector plots came from the m_map package
