Chromophoric DOM (CDOM) in the open ocean is an important factor controlling ocean color, and thus plays a role in photochemistry, photobiology, and upper ocean radiation budget. Our recent results have demonstrated transport of CDOM into the deep ocean and suggest remineralization-correlated new production of CDOM in the main thermocline and below. We here present a synthesis of results from time-series work at the Bermuda Bio-Optics Project site south of Bermuda, remote sensing, experimental work in the laboratory, and a global bottle sample field survey, which has resulted in a description of CDOM dynamics in the global ocean.
