Since the sea is pure only when it is deep, and is
transparent only when it is pure, as soon as it is impure it is no longer deep but only
surface water, and as soon as it is only
surface water it is not
transparent.
Dippers, which are equipped with a
transparent second eyelid (think
water goggles for birds), dive below the river's
surface and walk the riverbed scouring the rocky floor for meals, mostly aquatic insects in their larval stage.
Visible light from the Sun can not physically heat land or
water, and the Earth's
surface is largely
water, and,
water is a
transparent medium for visible light anyway.
Most of the remaining 82 % is radiated by
water vapour molecules from various heights in the atmosphere (depending on wavelength) and the
surface of the earth (particularly at wavelengths around 10 micron where the atmosphere is almost
transparent).
So
water can explained as same as atmosphere - sunlight is
transparent to
water, sunlight passes thru the
water and heats the
water under the
surface, and heat generated is blocked from radiating IR.
This means that 63.3 % (248Wm - 2) of the 391Wm - 2 emitted as LWIR radiant energy from the
surface is absorbed by
water vapour in 120m of traverse and the remainder 140Wm - 2 leaves the atmosphere as it is
transparent to it.
