在风持续吹向海岸的地方，地表水被迫离岸，并被从下面涌上来的营养丰富的水所取代。这一过程的历史是全球环境随时间变化的指标。作者研究了自中新世大面积冰川作用开始以来上升流变化的化石和化学记录。作者重点关注深海钻探探险的结果。这些新结果的综合为重建早中新世以来与上升流系统相关的时空古环境模式提供了独特的机会。这些模式应该揭示有关气候、海洋环流和海洋生产力变化的强迫和反馈机制的见解。
Where winds blow persistently alongshore, surface waters are forced offshore and are replaced by nutrient rich water upwelling from below. The history of this process is an indicator of global environmental change through time. The authors look at the fossil and chemical record of change in upwelling since extensive glaciation began in Miocene times. The authors focus on results from deep ocean drilling expeditions. Syntheses of these new results provide a unique opportunity to reconstruct the temporal and spatial palaeoenvironmental patterns associated with upwelling systems since the Early Miocene. These patterns should profile insights on forcing and feedback mechanisms that connect changes in climate, ocean circulation and marine productivity.
