The UV chromophore was ubiquitous in intermediate and deep waters, and it has been proposed as the secondary absorption peak of nitrate. The visible chromophore was prominent at the central and intermediate water masses of the North Pacific, and it has been proposed as cytochrome c. Subtraction of the modeled absorption spectra of the two chromophores from the measured absorption spectrum of the samples leads to a spectral slope overestimation by 13.3 ± 6.0% for S275–295 and 14.8 ± 10.6% for S350–400. To only consider the chromophoric fraction of DOM, the absorption spectra of nitrate should be subtracted in samples with a [NO3−]:a302 ratio > 70 µM mThis study was financed by the Malaspina 2010 circumnavigation expedition (grant CSD2008-00077)Peer ReviewedAmerican Geophysical UnionConsejo Superior de Investigaciones Científicas [https://ror.org/02gfc7t72]2016201620162016info:eu-repo/semantics/articlehttp://purl.org/coar/resource_type/c_6501Publisher's versioninfo:eu-repo/semantics/publishedVersionhttp://hdl.handle.net/10261/136505reponame:DIGITAL.CSIC.
