While coastal currents are caused by local winds, surface currents in the open ocean originate from global wind patterns. On the next page, you'll learn about these currents. More Surface Currents Circular wind patterns create five major gyres at the ocean's surface. Photo courtesy NOAA As...
Circular wind patterns create five major gyres at the ocean's surface. Photo courtesy NOAA As you've probably gathered by now, wind and water are inseparable. To understand surface ocean currents, which, as their name suggests, occur in the open ocean, you should know a little about the...
Wind waves are formed when the wind blows over the surface of the sea or a body of water. Wind creates up-and-down movement on the surface, amplified by friction with the water. Surface waves occur when there is a change in fluid pressure that travels from one side to another without c...
The temperatures of the deep-ocean set the ‘general background temperature’ for the Earth during different geological periods. Creating warm and cold climate states. Now we are living in an era of long glacials and short interglacials, our present era is an era within an Ice House Climate ...
Long periods are deduced from the difference between the raw signal and the sum of the components characteristic of the lower subharmonic numbers. This low-frequency component shows that the two studied glaciers formed in the mid-Holocene, then extended steadily until they stopped growing before ...
