LW IR can only heat the thin surface tension skin of the oceans and is evaporated away almost as soon as the thin skin warms. (wattsupwiththat.com)
I read the series from Science of Doom and discovered that DLR only warms the skin of the ocean and causes more evaporation and possibly cools the top few millimetres. (tamino.wordpress.com)
If it is colder in the atmosphere than in the skin of the ocean (the usual situation), there will be a net loss of energy from the ocean to the atmosphere. (scienceofdoom.com)
