Concept of optical proxies
Variable IOP or AOP
How to measure the variable (combination of proxies?)
Biogenic minerals (coccoliths)
What information does the IOP/AOP contain (multiple variables)?
absorption coefficientdirect IOP or inversion from AOPs: but – phytoplankton is only part of total aphyt, all pigments aps photosynthetically competent pigments fluorescencequasi-IOP or AOP (solar fluorescence)caution because of variable fdetermine pigment, then what? Convert to carbon? Use for physiology or PP model?
