Water temperatures increase along the coast as far as the Galapagos islands. Weak events will raise the water temperature 2 to 4 degrees Celsius and will have minor impact on fishing. However strong events such as the 1982-83 event will disrupt climate conditions around the world as well as local conditions. It has been linked to floods and droughts all over the world. Hurricanes and tropical storms are also altered in their numbers by El Nino. Therefore it would be very helpful for people if El Nino could be predicted and prepared for in some form. During a El Nino cycle there are many biological changes. Due to a depressed thermocline there is less photosynthetic activity resulting in a decrease in the primary life forms that form the beginning of the food chain. The warmer waters that are brought by these changing cycles hold less dissolved oxygen forcing fish to go deeper or venture
