LienA one-year analysis of Lagrangian measurements of Internal Waves and Turbulence in the Deep Cycle Layer in the Central Equatorial Pacific will be conducted. The goal is to quantify the properties of internal waves and turbulence in the deep layer. Specific objectives are to: (1) separate internal waves and turbulence based on the observed Lagrangian frequency spectrum; (2) examine the diurnal fluctuation of velocity variances and the spectral evolution of internal waves; (3) examine the diurnal fluctuations of the turbulent inertial subrange; and (4) estimate the vertical heat flux from Lagrangian measurements of temperature and vertical velocity.

将对中赤道太平洋深旋回层内波和湍流的拉格朗日测量结果进行为期一年的分析。目标是量化深层内波和湍流的性质。具体目标是：(1)根据观测到的拉格朗日频谱分离内波和湍流；(2)研究速度差的日变化和内波的谱演化；(3)研究湍流惯性子范围的日波动；(4)通过拉格朗日温度和垂直速度测量估计垂直热流密度。
