中文摘要
该项目将使我们对宁格鲁海流系统的理解取得重大进展,宁格鲁海流系统主导着宁格鲁海洋公园周围的区域环流,宁格鲁海流是国家海洋保护区代表系统的一部分。数值模型和野外测量将首次阐明驱动宁格鲁流的物理因素以及由此产生的上升流的时空变化。这将最终提供对各种生态过程如何与流体动力学(例如,养分输送,漂白)相关联的见解,并有助于评估珊瑚礁生态系统对气候变化引起的物理强迫变化的易感性。
英文摘要
This project will lead to significant advances in our understanding of the Ningaloo Current system that dominates the regional circulation surrounding Ningaloo Marine Park, part of the National Representative System of Marine Protected Areas. The numerical model and field measurements will, for the first time, elucidate which physical factors drive the Ningaloo Current and the resulting spatial and temporal variability of upwelling. This will ultimately provide insight into how various ecological processes are linked to hydrodynamics (e.g., nutrient delivery, bleaching) and help assess how susceptible the reef ecosystem may be to changes to physical forcing resulting from climate change.
