Looking to the future, starting in 1996 the POLDER instrument will measure the angular 
polarization properties of reflected sunlight. Although not all the spectral bands useful to ocean 
color remote sensing will have polarization capabilities, the data will provide the opportunity to 
test and verify many of the concepts and theoretical findings discussed above.
