ABSTRACTOCE-0351116In 2001 the Red Sea Outflow Experiment (REDSOX) obtained the first comprehensive survey of the outflow of Red Sea water into the Gulf of Aden. The objectives of REDSOX were (i) to describe the pathways and downstream evolution of the descending outflow plumes, (ii) to quantify the processes that control the final depth of the equilibrated Red Sea outflow water, and (iii) to identify the transport processes and mechanisms that advect Red Sea outflow Water and its properties through the Gulf of Aden and into the Indian Ocean. The field experiment and the final data processing have been successfully completed, and first results from the project have been published. This grant supports the analysis and synthesis of part of the data collected during the two REDSOX cruises such as high-resolution hydrographic and direct current surveys and direct measurements of turbulent mixing. The analysis will focus on the following specific objectives.1. Rationalize bulk estimates of entrainment, total stress and entrainment stress of thedescending plume with corresponding "direct" estimates based on overturning scales.2. Explore the three-dimensional circulation in the two outflow channels with focus on theeffects of rotation.3. Analyze Reynolds stress and turbulence structure above the sea floor and relate thebottom stress to the interfacial stress.4. Compare the properties and dynamics of the Red Sea plume with other outflows, suchas the outflow from the Mediterranean, to attempt to generalize the results with respectto other plumes and broaden the scope and impact of the synthesis activities.The completed synthesis will provide detailed insight into the Red Sea outflow and relatedcirculation processes in the Gulf of Aden. It will improve the understanding of descendingplumes in general, especially of the critical process of entrainment and mixing. Such knowledge is crucial for improved parameterizations of these processes in ocean circulation and climate models.

Abstractoce-0351116in 2001红海流出实验（RedSox）获得了对红海水流到亚丁湾的流出的首次全面调查。 RedSox的目标是（i）描述下降羽流的途径和下游演变，（ii）量化了控制平衡的红色海洋流失水的最终深度的过程，以及（iii）以识别通过Aden和Indian Indian Ocean的Gulf of Aden of Aden Ocean和Int the Indian Ocean的运输过程和机制。 现场实验和最终数据处理已成功完成，并且已发布了该项目的首先结果。该赠款支持在两次RedSox巡航过程中收集的数据的一部分数据的分析和合成，例如高分辨率水文和直流电流调查以及湍流混合的直接测量。分析将重点放在以下特定目标上。1。合理化基于倾覆量表的相应“直接”估计值的夹带，总应力和夹带应力的批量估计。2。探索两个流出通道中的三维循环，重点是旋转效果3。分析雷诺在海底上方的雷诺应力和湍流结构，并将骨压力与界面应力相关联。4。比较红海羽流的特性和动力学与其他流出，例如地中海的流出，试图通过其他羽毛概括​​结果，并扩大合成活动的范围和影响。完整的合成将提供详细的洞察力，可详细介绍Aden gulf的红海流出和相关流程的详细见解。通常，它将一般来说，尤其是对夹带和混合的关键过程的理解。这种知识对于改善海洋循环和气候模型中这些过程的参数化至关重要。
