The warm Gulf Stream originating in the tropical Caribbean, for instance, carries about 150 times more water than the Amazon River. Ocean currents are an important abiotic factor that significantly influences food webs and reproduction of marine organisms and the marine ecosystems that they inhabit. The Coriolis effect contributes to the direction of current flow. Today, scientists can study the Gulf Stream from above, using satellites. In areas where warm and cold currents meet, the temperature falls, giving rise to foggy conditions. Differences in water density, resulting from the variability of water temperature (Thermo) and salinity (haline), also cause ocean currents. What's a rogue wave?
