Although the ENSO event caused many organisms to die,
some species love the warm water. Nineteen different types of marine
animals liked the water and increased in number along the coast of west
South America in the 1982-83 event. This included the dolphin fish,
skipjack, bonita, tuna, scallop and shrimp. On land, coastal deserts in
South America bloomed with flowers and other plants. Even in the United
States, the corn yield always seems to increase during an El Nino.
Understanding the importance of an El
Nino/Southern Oscillation event involves many scientific concepts. More
importantly, an ENSO event illustrates the "chicken before the egg
problem" or the cause/effect relationship in true scientific terms.
