This energy is emitted by the sun, transmitted through the atmosphere and reflected by the earth surface.

The sunlight is not merely reflected from the sea surface. The color of water surface results from sunlight that has entered the ocean, been selectively absorbed, scattered and reflected by phytoplankton and other suspended material in the upper layers, and then backscattered through the surface.

The color of water surface is regulated by the color of pure ocean water and the concentrations of different types of particles suspended in the upper water layer.

Those storm cells looked pretty intimidating but you’re probably treating them like old unwanted friends by now and beating them to their game.
We’re envisioning The Risk making safe headway on a glistening green ocean with time for you to regroup and watch the sails billow.
Awaiting your first photos of Indonesia and your Kupang anchorage.
Love you so much. Mom XX
