Fairbanks Funds under the SGER program are provided to study the chemistry of the upper ocean in the tropical Pacific during the 1997 ENSO event. The funds will be used to complement a funded offshore coral drilling expedition on the R/V Moana Wave. Underway hydrographic data as well as more complete chemical and isotopic data from the upper ocean at profiles will be collected in the Nino 3 region on a cross-equatorial transect from Hawaii and Christmas island, at stations spacings of one degree latitude or less. The proposed nutrient, oxygen and fluorescence measurements that are proposed will form a base-line for comparison to prior and future studies of the changes in upper ocean geochemistry during El Nino and non-El Nino events. The oxygen isotope collection will improve our understanding of the convective system , its associated fresh water pathways and its impacts on the temperature and salinity stratification of the upper ocean. These processes are thought to be one of the sources of model failures in the some of the predictive ENSO models.

费尔班克斯 SGER计划的资金用于研究1997年ENSO事件期间热带太平洋上层海洋的化学。 这笔资金将用于补充R/V Moana Wave上资助的近海珊瑚钻探探险。将在Nino 3区域从夏威夷和圣诞岛的跨赤道断面上收集正在进行的水文数据以及更完整的上层海洋剖面化学和同位素数据，收集站间距为1个纬度或更少。提出的氧气和荧光测量将形成一个基线，用于与厄尔尼诺和非厄尔尼诺期间上层海洋地球化学变化的先前和未来研究进行比较。厄尔尼诺事件氧同位素的收集将提高我们的对流系统，其相关的淡水路径及其对上层海洋的温度和盐度分层的影响的理解。这些过程被认为是一些预测性ENSO模型失效的原因之一。
