temperature: 1,000 m depth temperature = 5C thermal conductivity of seawater 0.58 W / mK ocean - air interface = 17.000 C 1.441 mm depth temperature = 17.400 C (the warmest spot in the ocean depth though the «few metres» of depth below it is only a miniscule bit colder, all warmed by Sun SWR) this top 1.441 mm depth is the «skin» and «sub-skin» 100m depth temperature certain in range 16.090 C to 17.400 C but virtually certain > 17C because of mixing top ~ 90m temperature gradient of top 1.441 mm of ocean is 277.6 Celsius / metre By conductivity, temperature gradient pushes 161.00 w / m ** 2 up from 1.441 mm depth to ocean - air interface which precisely removes the Sun's 161 w / m ** 2 going into the top few metres depth and leads to no ocean warming.
