I am interested in finding out some information on the value of
light intensity that are not available in most photosynthesis 
text book:

1) What are the intensities of the sun light in a typical
summer morning (say 25 C) and afternoon (35 C)?

2) By how much is the light intensity reduced after passing
through 2 - 3 metres of sea water? A formulae will be more

Thanks in advance.
