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.

将在莫诺湖研究MacIntyre/ Monismith/Schladow过程实地研究，以记录从流域尺度模式到高频波再到湍流运动导致边界混合的能量转移。为了理解这些能量通道，将进行四项基本任务：（1）利用现场观测和数值模拟确定盆地尺度运动的变化;（2）记录高频内波场的强度、频谱分布和时间变化;（3）测量边界附近的湍流混合及其效率;（4）混合流体和再悬浮泥沙在边界上的再分布观测。
