MacIntyre/ Monismith/ SchladowProcess field studies to document the energy transfer from basin scale modes to high frequency waves to turbulent motions leading to boundary mixing will be studied in Mono Lake. Four tasks that are essential for understanding these energy pathways will be pursued: 1) a determination of the variability of basin-scale motions using field observations and numerical modeling; 2) a documentation of the strength, spectral distribution and temporal variability of the high frequency internal wave field; 3) measurements of turbulent mixing and its efficiency near the boundary; and 4) observations of the redistribution of mixed fluid and resuspended sediment from the boundary.

将在莫诺湖进行现场研究，以记录从盆地尺度模式到高频波到湍流运动导致边界混合的能量转移。对理解这些能量路径至关重要的四项任务将被追求：1)利用野外观测和数值模拟确定盆地尺度运动的变异性；2)记录高频内波场的强度、频谱分布和时间变化；3)边界附近湍流混合及其效率的测量；4)混合流体和重悬沉积物在边界的再分布观测。
