(7) Explain the effects of photoinduced and microbial processes on CDOM
absorption properties in waters.
(8) Explain the effects of photoinduced and microbial degradation of CDOM on
spectral slopes.
(9) What are the effects of monochromatic and polychromatic irradiation on
CDOM absorption spectra?
(10) Why are the CDOM absorption losses by irradiation significantly different
for a variety of natural waters?
(11) How does salinity affect CDOM absorption in oceans?
(12) 'All colored DOM is chromophoric DOM, but not all chromophoric DOM is
colored'- Explain this concept.
(13) Explain shortly the applications of remote sensing to surface waters.
(14) Explain the impacts of photoinduced degradation of CDOM in waters.
