We are making progress on finding the actual chemical compounds or phenomena responsible for DOM's optical properties. Ultrahigh resolution mass spectrometry, in particular, has made important progress in making the key connections between optics and chemistry. But serious questions remain and the last major special issue on DOM optics and chemistry occurred nearly 10 years ago. Controversies remain from the non-specific optical properties of DOM that are not linked to discrete sources, and sometimes provide conflicting information. The use of optics, which is relatively easier to employ in synoptic and high resolution sampling to determine chemistry, is a critical connection to make and can lead to major advances in our understanding of organic matter cycling in all aquatic ecosystems. The contentions and controversies raised by our poor understanding of the linkages between optics and chemistry of DOM are bottlenecks that need to be addressed and overcome. 606 $aChemistry$2bicssc 610 $aAbsorbance 610 $abiomarkers 610 $aCDOM 610 $adissolved organic carbon 610 $adissolved organic matter 610 $afluorescence 610 $aMass Spectrometry 610 $aStable isotopes 615 7$aChemistry 700 $aThomas S.
