最近对海洋温度的系泊观测首次提供了印度尼西亚海域马卡萨尔海峡温度变化的高分辨率长期记录。系泊观测涵盖了1997/1998年强厄尔尼诺的整个周期。一个高的相关性（r = 0.67）被发现之间的变化，在平均温跃层温度，在向南的马卡萨尔体积运输的变化：在高（低）体积运输，温跃层的平均温度也高（低）。此外，从近15年的XBT数据来看，马卡萨尔温跃层温度与SOI高度相关（r = 0.77）。这表明，马卡萨尔温度场-当与通流耦合时-将赤道太平洋厄尔尼诺和拉尼娜温度波动传递到印度洋。计算出内部能量输送的ENSO变率：1996年12月至1997年2月的拉尼娜月份为0.63 PW，1997年12月至1998年2月的厄尔尼诺月份为0.39 PW。
Recent mooring observations of ocean temperature provide the first high resolution, long term record of temperature variability in the Makassar Strait of the Indonesian Seas. The mooring observations span the entire cycle of the strong 1997/1998 El Niño. A high correlation (r = 0.67) is found between variability in the average thermocline temperature, to variability in the southward Makassar volume transport: during high (low) volume transport, the average temperature of the thermocline is also high (low). In addition, from nearly 15 years of XBT data, the Makassar thermocline temperature is shown to be highly correlated (r = 0.77) to SOI. This reveals that the Makassar temperature field–when coupled with the throughflow–transmits the equatorial Pacific El Niño and La Niña temperature fluctuations into the Indian Ocean. The ENSO variability in the internal energy transport is calculated: 0.63 PW during the La Niña months of December 1996 through February 1997, and 0.39 PW during the El Niño months of December 1997 through February 1998.
