Extracted text: In the first part of this investigation, imaginary pressure blocks were applied to demonstrate the sloping of the ocean surface when warm water and cold water are situated side-by-side. Knowing that surface water on a sloping ocean surface is pulled downhill by gravity, we saw that Earth's rotation deflects the moving water (to the right in the Northern Hemisphere) until it flows essentially along a contour line (a line of equal water height). We then examined the Gulf Stream flowing along the transition between warmer and colder water and employed the pressure blocks to model the Gulf Stream and associated warm and cold eddies (rings). 20. Figure 10A-8 displays the relationship between SSTS and mean velocity of the Gulf Stream along a straight-line track between New Jersey and Bermuda. The figure is based on data collected using an acoustic Doppler current profiler during weekly crossings over a six-year period by the freighter Oleander (and its predecessors). The depiction is a composite plot of all crossings. Color shadings represent SSTSS. Dark straight lines drawn from positions along the ship's path indicate the mean speed of the ocean current perpendicular to the ship's travel. The longer the line, the greater the speed of the current. Locate the longest line. Place an arrowhead on the line’s northeast end to make an arrow (vector) that represents the speed and direction of the current. The tail of the arrow, located at the ship's position, shows that the maximum mean velocity of the Gulf Stream occurred at about ΟN, 70-W. а. 35.4 b. 36.4 c. 37.4 40 38 37 35 34 33 -73 -71 -70 64 -69 -68 longitude 72 67 Figure 10A-8.
