Assessing the prevalence, products, and pathways of dissolved organic matter partial photo-oxidation in arctic surface waters
Collin P. Ward, Rose M. Cory
Abstract
. A sensitivity analysis based on this new knowledge demonstrated that the magnitude of DOM partial photo-oxidation may be underestimated by up to four-fold. Consequently, partial photo-oxidation likely plays a more prominent role in shaping DOM composition in sunlit waters of the Arctic than previously understood. Therefore, partial photo-oxidation should be increasingly incorporated into the experimental framework of studies focused on DOM composition in surface waters.
