You note the notations on the graph above for 100m, 10m, 1m, 1cm, and surface. These are the regions of DWSR and what in the ocean they affect. Anything larger in wavelength 1.1um (1100nm) will impact the skin of the ocean and be defeated in the evaporation layer. (First ten microns) The layer just below this is about 150 microns in depth and is cooler than the evaporation layer. Even with mixing from waves, the energy that impacts the skin is too small to generate heat into the oceans due to the mixing with the colder region.
This graph demonstrates how a minor shift in energy output on our sun can directly affect our oceans. Over 90% of the energy into our oceans occurs in the 380nm to 540nm region. A 5% shift from this region to 1.0-1.4um would put the energy outside the ability for most of the ocean to absorb.
The shift in energy that affected our solar panel arrays is in the same region that affects our oceans. The PV arrays lost 10% of their output, indicating at least that amount of shift in power from the sun. If approximately 5% of that energy falls in the primary ocean heating area this can affect our oceans uptake of 345W/m^2, were looking at a potential change nearing 16W/m^2 and the reason our ENSO is not recharging, and our oceans are cooling.
This also demonstrates why "back radiation" or LWIR that is emitted by CO2 cannot warm our oceans. The wave is too long to penetrate the oceans evaporation layer in all three of its bands of emission. Even with mixing the mass of the evaporating layer is insufficient to warm the thermocline barrier just below it that is about 150 microns in depth.
