V. Part 5. Annual Mean Current Velocities - Building a Model View: https://youtu.be/I0d9Db9dvlg (4 minutes-long) In order to make sense out of the drifter data, we need to do a simple routine of data analysis by averaging the velocity of the all buoys in a given area of each ocean over a year (velocity is both the speed and direction). We will use the terms "mean" and "average" interchangeably. In doing so, oceanographers can plot the Annual Mean Current Velocity of each drifter in equally spaced regions throughout the Pacific Ocean as shown in the video. The arrows, known as vectors, on the diagram of Annual Mean Current Velocity in the Pacific Ocean, represent averages of the surface currents over several years in centimeters per year (1 inch = 2.54 cm) and do not include the important variations and complications shown in the buoy trajectories (variance in statistics jargon) due to ocean eddy currents, which are irregular circular currents many 10's to 100's kilometers in diameter. Vectors are arrows that show the direction of movement plus the length of the arrows is proportional to the speed of motion - the longer the arrow - the faster the motion. On the
