waves, big waves, small waves, breaking news about breaking waves
... ALL the sediments have sediments above and below them. This can happen by settling out or by successive deposition by waves. Just think it through with an eye to how it COULD HAVE WORKED.
Breaking waves pick up objects, the more energy in the breaking waves (a function of height) the larger is the material picked up
Large storm waves scour the beaches of sand and transport it offshore into bars. Smaller waves that break over the bars can pick up the finer material and transport it back to the beach. I see this all the time at my parents house on Cape Cod. One of the things I would like to do is install a camera that takes a picture at each low tide so you can observe how the beach moves back and forth.
These storm waves will pickup any silt or sand layers, so your global waves have no hope of leaving them undisturbed while they lay another layer down -- the fines will be mixed up.
Waves that don't break do not move sediment -- this is why the storm waves drop the sand etc as it is carried away from shore once the sediment is carried out to the area of non-breaking waves.
Curiously people have studied how waves actually work (I know a scientist at Scripps Oceanographic that actually studies waves ... ), and so they KNOW how waves work.
In a longitudinal wave the particle displacement is parallel to the direction of wave propagation. The animation at right shows a one-dimensional longitudinal plane wave propagating down a tube. The particles do not move down the tube with the wave; they simply oscillate back and forth about their individual equilibrium positions. Pick a single particle and watch its motion. The wave is seen as the motion of the compressed region (ie, it is a pressure wave), which moves from left to right.
Notice the red dots moving back and forth. The only way material is transported is when the wave breaks and falls into the trough. Now a cross section view (same link):
Water waves are an example of waves that involve a combination of both longitudinal and transverse motions. As a wave travels through the waver, the particles travel in clockwise circles. The radius of the circles decreases as the depth into the water increases. The movie below shows a water wave travelling from left to right in a region where the depth of the water is greater than the wavelength of the waves. I have identified two particles in yellow to show that each particle indeed travels in a clockwise circle as the wave passes.
Notice how the (circular) movement diminishes with depth, and at about 3 wave-heights (crest to trough) it is essentially still. If the bottom is above this range it will cause the wave to trip, which is why waves break on shores.
A wave breaking on shore will pick up and suspend material with the size depending on the wave height\energy. Large waves will deposit rocks on the beach and keep sand and silt suspended as the waves return. This can cause scouring on the beach and I have seen rocks exposed at low tide covered by sand before a storm and then uncovered by the storm (and the sand/silt/fines that are suspended are deposited on a sand bar just out of the active wave action area.
Non-breaking waves do not transport material from one location to another, they do not disperse sediment or suspended particles.
Breaking waves scour the bottom and suspend particulate matter in the turbulence of the breaking wave, with the size of the suspended particles related to their size and settling velocities.
Your succession of waves (a) will not deposit graded layers on top of graded layers and (b) will not leave layers of silt behind.

The above is (somewhat simplified) how it DOES WORK. I don't have to imagine it.
Re: waves, big waves, small waves, breaking news about breaking waves
I have claimed nothing about nonbreaking waves and you already put all that up to debunk the Flood back when you didn't have a clue I couldn't have been talking about nonbreaking waves.
Great -- I will hold you to this: no non-breaking waves involved in the magic of flood geology.
However, ocean water DOES move stuff. Why does all that junk end up on those little islands? Why do bottles with messages in them finally make land across the world? ...
You mean the floating stuff that gets blown by winds? Curiously no rocks, pebbles, or sand are deposited on those little islands from the mainlands or even from other little islands.
Below the turbulent layer of breaking waves the water behaves the same as below non-breaking waves. The breaking wave turbulent layer can result in temporary currents at the surface as they are blown downwind.
... The ocean also has layers in it, apparently at different temperatures, and it has currents as well as waves. ...
Indeed there are ocean currents. The Gulf Stream is well known for running up the east coast and then east below Greenland to get to England. But without continents this current would not exist. Ocean currents like this also do not transport rocks, pebbles and sand for deposition in far places. People have known about these currents since the dawn of navigation, Faith. The average speed is 4 mph -- an easy walking pace.
There are also deep ocean currents, and they too are impacted by the geology of the ocean bottom. They also do not move fast enough to transport rocks, pebbles, sand and dense materials for deposition in far places.
The relative velocities of water in a section across these currents is called a velocity ofile, with speed plotted against distance. It looks something like this:
... similar to the velocity profile across a river channel, except here the edge of the "channel" is tranquil water.
The flow is laminar (no turbulence) and increases from the outer boundary to the center, so the relative velocity compared to adjacent water is very slow, so they are not transport currents, they are not capable of carrying rocks, pebbles and sands for deposition in far places. The speed of these currents is very slow, as we can know from the age of the water at upwelling points (where it comes back to the surface when it runs into continents) -- some of the water has been away from the surface for over 1000 years. Upwelling points do not deposit silts.
Water currents from river deltas are faster, and the materials carried by the rivers gets deposited as the water spreads out and slows down. The deltas are built up bt the deposition of sediments carried by the river, and you can observe the limits to distance for different size particles in the deltas. There is no transport and deposition rocks, pebbles, sand and dense materials to far places.
... Don't get too minutely scientific about something until we have a better idea of the various ways the Flood might have worked.
And everyone is waiting for you to catch up with the rest of the world on that.
Something that is not contradicted by known objective empirical evidence is objectively possible (and anything that IS contradicted by known objective empirical evidence is objectively NOT probable.
To be "OBJECTIVELY PLAUSIBLE" you need to demonstrate the plausibility, and simply not being contradicted by known objective empirical evidence is not sufficient, because "plausible" is a higher standard than "possible" and you can't conflate the two.
... AND OBJECTIVELY A SERIOUS CHALLENGE. ...
Objectively it is a possible challenge. To rise to the level of serious challenge you need to have objective evidence supporting your claim.
So far you do not have a mechanism that can put down a layer of silty deposition and then cover it with a layer of gravel. Your waves do not accomplish this because they will erode the silty layer back into suspension. The world is covered with layers of silty material buried by coarser layers - in some places thousands of alternating layers.
To have a plausible explanation you need to show how alternating layers can happen, and then have test results to show that it is more than just a hypothetical possibility.
