Short summary
Short summary
Compared with mode-1 internal solitary waves (ISWs), mode-2 ISWs in the ocean require further study. A mass of mode-2 ISWs developing at the Pacific coast of Central America have been imaged using seismic reflection data. We find that the relationship between the mode-2 ISW propagation speed and amplitude is diverse. It is affected by seawater depth, pycnocline depth, and pycnocline thickness. The ISW vertical amplitude structure is affected by the ISW nonlinearity and the pycnocline deviation.

Short summary
Internal tides are ubiquitous in the world's stratified oceans and play an important role in a wide variety of ocean processes. I developed a new-generation internal tide model, ZHAO30yr, using 30 years of satellite altimetry data. ZHAO30yr contains 12 (eight mode-1 and four mode-2) internal tide constituents. ZHAO30yr decomposes the global internal tide field and reveals numerous long-range beams that contain important information on their generation, propagation, and dissipation.

Short summary
With seismic data, we observed high-frequency internal waves (HIWs) with amplitudes of around 10 m. A shoaling thermocline and gentle slope suggest that HIWs result from fission. Remote sensing data support this. Strong shear caused Ri below 0.25 over 20–30 km, indicating instability. HIWs enhance mixing, averaging 10-4 m2s-1, revealing a new energy cascade from shoaling waves to turbulence, and enhancing our understanding of energy dissipation and mixing in the northern South China Sea.

Short summary
This study examines the seasonal variability in internal tide sea surface height in a global model simulation. We also compare this with altimetry and the seasonal variability in the internal tide energy terms. Georges Bank and the Arabian Sea show the strongest seasonal variability. This study also reveals that sea surface height may not be the most accurate indicator of the true seasonal variability in the internal tides because it is modulated by the seasonal variability in stratification.

Short summary
Satellite altimetry provides a unique technique for observing the sea surface height (SSH) signature of internal tides from space. The advances in mapping technique, combined with the accumulation of satellite altimetry data, make it possible to construct empirical models for minor internal tide constituents. This paper demonstrates that N2 internal tides, the fifth largest tidal constituent, are observed using 100 satellite years of SSH data from 1993 to 2019 by a new mapping procedure.

Short summary
When the internal solitary wave propagates to the continental shelf and slope, the polarity reverses due to the shallower water depth. In this process, the internal solitary wave dissipates energy and enhances diapycnal mixing, thus affecting the local oceanic environment. In this study, we used reflection seismic data to evaluate the spatial distribution of the diapycnal mixing around the polarity-reversing internal solitary waves.
When the internal solitary wave propagates to the continental shelf and slope, the polarity...
