Fall, a season more associated with leaves falling from trees for most, means a completely different thing to a fisherman. It’s not the falling leaves we are concerned with, it’s the falling water that means so much to us in the later months of each year. Warm water rises, cold water sinks. This simple truth is the guiding principle of all our vast oceans’ movements and currents. These very movements create the predictable patterns in ocean life that, when studied, help us determine lure size, lure color, and what a lure should imitate to attract fish.
The Conveyor is the term many oceanographers use to describe the oceans’ major currents. If you understand the Conveyor, then you can learn the movements of the things that live in the ocean. From the tiny to the great, all things in the ocean live inside the great conveyor, and it gives them oxygen, food, and life itself.
Ocean currents flow over vast distances: these currents push against each other and in total they create the great flow of the global conveyor belt. An ocean current is a continuous, directed movement of seawater generated by forces such as wind, temperature, salinity differences, and tides caused by the pull of the moon. Other factors like underwater contours and the shape of a shore line can influence the direction or the power of a current, but typically don’t cause the current.
