绿色海龟（Chelonia mydas）是在澳大利亚北方和印度尼西亚繁殖的六种海龟之一。观察到的筑巢的绿色海龟的数量每年都有很大的变化。在相隔很远的栖息地，筑巢海龟数量的年际波动是同步的。它们还与南方涛动指数相关，南方涛动是一种大气压力、温度和降雨波动的连贯模式，主导着热带太平洋气候的年际变化。海龟繁殖数量的重大波动发生在南方涛动重大波动的两年后。这种关系足够强，可以提前两年预测在大堡礁栖息地繁殖的绿色海龟的数量。这是第一项报告南方涛动对生物影响的研究，允许对影响进行长期预测。
The green turtle (Chelonia mydas) is one of six turtle species which breeds around northern Australia and Indonesia. The number of green turtles observed nesting varies substantially from year to year. The interannual fluctuations in the number of nesting turtles are in phase at widely separated rookeries. They are also correlated with an index of the Southern Oscillation, a coherent pattern of atmospheric pressure, temperature and rainfall fluctuations which dominates the interannual variability of the climate of the tropical Pacific. Major fluctuations in the numbers of turtles breeding occur two years after major fluctuations in the Southern Oscillation. The relationship is strong enough to be useful in predicting, two years in advance, the numbers of green turtles breeding in Great Barrier Reef rookeries. This is the first study to report a biological impact of the Southern Oscillation that allows such a long-range prediction of the impact.
