Rosenfeld 9619466 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.

Rosenfeld 9619466将使用一套垂直细尺度和微结构剖面仪和船上仪器测量蒙特利海底峡谷内的内波和湍流场特征，以验证这一假设：峡谷上游传播的半日内波的能量通量被湍流耗散和混合所损失。与在公海中发现的相比，在细尺度(波长10-50米)上垂直波数谱的形状、水平非均质性和各向异性也令人感兴趣。最后，湍流测量将被用来评估峡谷对边界混合的重要性。
