The discussion centers on the behavior of water pressure at a depth of 10 meters below the ocean surface in relation to surface waves. It is established that while shallow water waves cause movement at depth, deep water waves do not affect pressure at depth significantly. Tsunamis, classified as shallow water waves, have pressure effects that can be felt throughout the water column, unlike surface waves generated by wind. The conversation highlights the importance of understanding wave dynamics and pressure gradients in oceanography.
PREREQUISITESOceanographers, marine engineers, environmental scientists, and anyone interested in the dynamics of ocean waves and their effects on underwater pressure.
It's down to the total volume of water displaced, I suppose. If the deep water height is 1m and the wavelength is 1km then it stands on its end when entering shallow water. You can easily get tens of metres of height.olivermsun said:FWIW, the vertical displacement due to tsunamis traveling in the deep ocean is typically very small.
No. It is rather complicated, because you have to include dynamic pressure, and not just the hydrostatic pressure (use Bernoulli's Equation). It's not static, if there are waves, and dynamic pressure comes from the fact that the water is moving and accelerating, which requires forces/pressure. How it behaves depends on the depth of the water. See here, e.g. http://web.mit.edu/2.016/www/handouts/Free-Surface-Waves.pdfTreva31 said:If you are stationary say 10m below the ocean surface does the water pressure at your location vary with the waves.
For example:
When a wave crest is above you than means perhaps 12m of water is above you.
Then a few seconds later a trough is above you so only 8m of water is above you.
So you might expect your pressure reading to be going up and down with the waves?
