9617713 Loubere This project will reconstruct the geographic and temporal patterns of surface ocean production in the eastern equatorial Pacific over the past 150,000 years. Reconstructions will be based on a relationship between taxonomic assemblage of benthic foraminifera and surface production determined by factor and regression analysis using modern material. The project will expand on existing work which indicates regionally complex gradients in productivity over time, with significant differences from trends inferred using geochemical indicators of production.

9617713鲁伯雷该项目将重建过去150,000年来赤道东太平洋表层海洋生产的地理和时间模式。重建将以海底有孔虫的分类组合与地表产量之间的关系为基础，这一关系由使用现代材料的因子和回归分析确定。该项目将扩大现有的工作，这些工作表明，随着时间的推移，生产力的区域复杂梯度，与使用生产的地球化学指标推断的趋势有很大不同。
