Kunze 9633315 The characteristics of the internal waves and turbulence field in Monterey Submarine Canyon will be measured with a suite of vertical fine-scale and microstructure profilers and shipboard instruments to test the hypothesis the energy flux of up-canyon propagating semi-diurnal internal waves is lost to turbulent dissipation and mixing. Also of interest are the shape, level heterogeneity and anisotropy of the vertical wavenumber spectrum on the fine- scale (wavelength 10-50 m) as compared to that found in the open ocean. Finally, the turbulence measurements will be used to assess the importance of canyons to mixing at boundaries.

昆泽9633315 将使用一套垂直细尺度和微结构剖面仪和船载仪器测量Monterey Submarine峡谷的内波和湍流场的特征，以检验峡谷向上传播的半日内波的能通量损失于湍流耗散和混合的假设。同样令人感兴趣的是，与在开阔海洋中发现的垂直波数谱相比，细尺度（波长10-50米）上垂直波数谱的形状、水平不均匀性和各向异性。 最后，湍流测量将用于评估峡谷在边界处混合的重要性。
