OCE-9416971 Funding is provided for wireline drilling on drowned reefs in the tropical Pacific atolls (Christmas and Kanton) to determine whether tropical Pacific sea surface temperatures were significantly cooler in the past, as well as provide information about the behavior El Nino Southern Oscillation. In global change framework, the response of tropical sea surface temperatures to increasing atmospheric CO2 and other radiatively important trace gases is hard to predict accurately. Fundamental to these predictions is an understanding of whether tropical sea surface temperatures have been constant throughout the past or varied up to 5 degrees C in less than 5000 years.

OCE-9416971 为在热带太平洋环礁（圣诞节和坎顿）的淹没珊瑚礁上进行电缆钻探提供了资金，以确定过去热带太平洋海面温度是否明显较低，并提供有关厄尔尼诺南方涛动行为的信息。 在全球变化框架下，热带海表温度对大气CO2和其他重要辐射示踪气体增加的响应很难准确预测。 这些预测的基础是了解热带海洋表面温度在过去是否一直保持不变，或者在不到5000年的时间里变化高达5摄氏度。
