An oceanic gyre is a system of rotating ocean currents. Ocean currents almost mirror these wind patterns. However, continents get in the way of the flow of water. When currents encounter land, they are deflected and form circular patterns, called gyres, around the perimeter of Earth’s oceans and seas. The Coriolis Effect acting on these currents causes Northern Hemisphere gyres to move in a clockwise direction and Southern Hemisphere gyres to move in a counterclockwise direction. Earth receives more solar radiation at the equator than it does at the poles, and this uneven distribution of heat creates pressure differences, which in turn causes the movement of wind. Earth’s rotation causes fluids—both wind and water—to be deflected as they move across our planet’s surface. This is known as the Coriolis Effect. The Coriolis Effect causes winds to move in an eastward or westward direction in addition to their northward or southward flow. The Great Pacific Garbage Patch, also described as the Eastern Garbage Patch or the
