The R/V Laurence M. Gould is a major research platform for ocean and climate studies. It is also the principal supply vessel for the U. S. Antarctic Program research station at Palmer Station, Antarctica. It routinely travels from Punta Arenas, Chile to the Antarctic Peninsula region, crossing the Drake Passage 2 to 4 times per month. 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 "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. 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 plot, click on the Capital letter(s). If the difficulty is that the labels are packed too tightly, try going to the section list (from any vector or contour plot) and loading from there.
