The optics of chromophoric dissolved organic matter (CDOM) in the Greenland Sea were investigated and compared to results from earlier studies Southeastern North Sea. Absorption at 375 nm (a ) varied 0.77 m −1 detection limit our instrument (0.05 ), with highest values found during summer. spectral slope coefficient (S) ranged 8.2 26.4 µm occurring winter. Seasonal variations situ production degradation CDOM where shown be responsible for trends seen. A negative correlation between S a was evident differed noticeably that coastal waters. differing S‐a behavior known terrestrial origin allowed development an algorithm differentiation marine matter. modeled by = 7.4 + 1.1/a .
