Internal Waves and Turbulence in Monterey Submarine Canyon

本文将利用一套垂直细尺度、微结构剖面仪和船载仪器对蒙特雷海底峡谷内波和湍流场特征进行测量，以验证沿峡谷向上传播的半昼夜内波能量通量因湍流耗散和混合而损失的假设。同样令人感兴趣的是在细尺度上（波长10-50 m）垂直波数谱的形状、水平非均质性和各向异性，与在公海中发现的波数谱相比较。最后，湍流测量将用于评估峡谷对边界混合的重要性。

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.
