Answer:

yes clear water reflects light

Liquid water has a higher albedo when the sun angle is low. For example, just after the sun rises the sun angle will be low and much of the radiation will be reflected by the water. This has important implication in locations the sun angle is low such as in high latitudes. High latitude locations where the sun is near the horizon will reflect more solar radiation away than at low latitude locations. This is one reason that high latitude locations are colder (with the main reason being that the sun's energy is spread over a larger surface area in high latitude regions).

When the sun is well above the horizon (30 degrees to directly overhead) then water has a low albedo and absorbs a great deal of solar radiation. The middle latitude and tropical oceans absorb an enormous amount of solar energy.

Ice is a good reflector of solar radiation especially if it is a fresh snowfall. The albedo decreases as the age of snow increases.

Here is a guide to the albedo of water at various states and sun angles:

fresh snow: 80%

sun near the horizon on water: 65%

old or dirty ice: 40%

water with a sun angle 30 degrees or more above the horizon: 8%
