Into the darker depths
As our diver continues to descend only a few more meters, she begins to go from day to night. She can see blue light to her sides, and white light above, but below her the view is dark. As she moves downward, the UV, green, and violet wavelengths disappear, and the light becomes an intense, almost laser-like, pure blue. At 200 meters deep, the diver would cross from the surface realm (called the epipelagic zone), where there is enough sunlight for photosynthesis, to the twilight realm (called the mesopelagic zone), where enough sunlight penetrates for vision, but not for photosynthesis.By now, our descending diver would notice nearly continuous blue flashes around her—bioluminescent light produced by animals in the midwater zone, in response to the disturbance in the water that she caused. Below 850 meters, though, the diver would no longer be able to see anything, even looking up. Human eyes aren’t sensitive enough to detect the minute amounts of sunlight that haven’t been absorbed by the water. At 1,000 meters, even the most visually sensitive deep-sea animals can longer see the sun. The region below this is known as the aphotic (no-light) zone, but this is only true for sunlight, as bioluminescence is common.
Shedding Light on Light in the Ocean
Light in the ocean is like light in no other place on Earth. It is a world that is visibly different from our familiar terrestrial world, and one that marine animals, plants, and microbes are adapted to in extraordinary ways. Light behaves very differently when it moves from air into…

And a purely scientific paper that deals with UV absorption.
And here is the long wave IR limitations, one of many. And every one of these "studies" tries to come up with a mechanism for the IR effect to penetrate beyond the skin of water because they know that without that capability their theories are dead in the water. The problem, of course is that HEAT RISES! So no amount of silliness is going to be able to show IR penetrating deeper than a few millimeters in the best of circumstances.
Which means, that UV, and ONLY UV, has the capability to penetrate deep enough to affect ocean temperatures. No matter how many computer models they come up with that simple fact is always going to bite them in the ass.
"It is, however, not clear how the greenhouse effect directly affects the ocean's heat uptake in the upper 700 m of the ocean. This is because the penetration depth of IR radiation in water is within submillimeter scales (Figure 1) thereby implying that the incident longwave radiation does not directly heat the layers beyond the top submillimeter of the ocean surface. The objective of this study is therefore to understand and provide an explanation of how increasing levels of anthropogenic GHGs in the atmosphere, which raises the amounts of incident longwave radiation on the ocean surface, causes the upper OHC to rise. Furthermore, at submillimeter scales below the air-sea interface, the mechanism for the transport of heat is through molecular conduction and not by turbulence (e.g., Soloviev & Lukas, 2014). Given the mean vertical temperature gradient of the TSL, heat typically flows from the ocean to the atmosphere, therefore heat from the absorption of longwave radiation will be conducted upward, back to the sea surface. This raises questions about the cause of the observed increase in upper OHC as it suggests that all heat due to the absorption of increased longwave radiation should be concentrated in the upper submillimeter from the interface. We hypothesize that variations in the temperature gradient within the TSL, which is directly affected by the absorption and emission of longwave radiation, modulates the amount of heat loss from the air-sea interface. Thus, any changes in the vertical temperature gradient in the TSL due to variations in the absorbed longwave radiation could provide an explanation of the mechanism as to how the OHC increases through the retention of heat from the absorption of solar radiation within the bulk of the ocean."

Thanks for validating YOU HAVE NO EXPLANATION FOR A SPIKE DOWN.
LEGIT REASON FOR SPIKE UP = NEAR TECTONICALLY ACTIVE VOLCANICALLY ACTIVE AA PENINSULA
How is that saying that the primary wavelengths that warm the ocean isn’t infrared (IR) and visible light, specifically the longer wavelengths within the visible spectrum?

Because they explicitly say that IR can't penetrate the skin of water, so they try and invent ways of transmitting the surface boundary interaction deeper into the water, all the while ignoring the well known fact that heat RISES!
You don't need to Google that which has been known for centuries.

But if oceans were warming, there would be a breakout in cane activity, and THERE IS NOT... which proves oceans are NOT WARMING...

The Climate Crisis – A Race We Can Win
Climate change is the defining crisis of our time and it is happening even more quickly than we feared. But we are far from powerless in the face of this global threat. As Secretary-General António Guterres pointed out in September, “the climate emergency is a race we are losing, but it is a race we can win”.
No corner of the globe is immune from the devastating consequences of climate change. Rising temperatures are fueling environmental degradation, natural disasters, weather extremes, food and water insecurity, economic disruption, conflict, and terrorism. Sea levels are rising, the Arctic is melting, coral reefs are dying, oceans are acidifying, and forests are burning. It is clear that business as usual is not good enough. As the infinite cost of climate change reaches irreversible highs, now is the time for bold collective action.

Another GDF IQ<5 Faux News parrot.
NO IT IS NOT WARMING....
But they can't tell you how it works. They make a claim to support their AGW theory, but can't explain the mechanism of operation.
We KNOW that UV penetrates to 500m. We KNOW that IR doesn't. They LIE when they say IR is the cause of ocean warming.
Just like they lie about everything else.

Classic and spot on
BBC on the Climate Crisis Catastrophe
How what works? Waves mix the surface waters. Its not a secret.
HEAT RISES! PHYSICS! LEARN IT!
Heat radiates in all directions as it equilibrates. Waves mix surface waters with deeper waters. By your logic UV rays would only heat to the depth they penetrate and then rise. By your logic there would no thermal gradient below the depth of penetration.
Heat naturally travels from hotter objects or regions to colder ones. This is a fundamental principle of thermodynamics. Heat transfer occurs until the objects reach the same temperature, a state of thermal equilibrium. So not physics. Thermodynamics.
No, it doesn't. HEAT RISES. Simple physics. You should study it.

How do you explain the existence of a thermal gradient below the depth of UV penetration? Where did that heat come from?
I have.
