The project was supported by NSF through grants OCE 0751226 (APL/UW, PIs: Michael Gregg, Matthew Alford, and Ren-Chieh Lien) and 0751420 (U of Hawaii, PI: Glenn Carter). It combined modelling and intensive field observations in the Monterey Submarine Canyon and Ascension canyon.
The specific objectives of this project were to:
- Understand how much M2 energy in Monterey Canyon comes from offshore vs. internal generation.
- Understand how the internal tide propagates around bends.
- Understand why the internal tide in Monterey Canyon sometimes produces standing instead of propagating waves.
- Quantify the mixing and parameters of mechanisms producting it, e.g., scattering lee waves and jumps.
- Measure the internal tide flux into the nearby Ascension Canyon and identify and quantify mixing along the canyon's axis.
