Ongoing environmental shifts affect freshwater discharge to the Arctic Ocean, and alter Arctic land-ocean fluxes. The monitoring of DOC distribution and CDOM optical properties is of great interest both from the point of view of validation of remote sensing models, and for studying organic carbon transformation and dynamics. In this study we report the DOC concentrations and CDOM optical characteristics in the mixing zones of the Ob, Yenisei, Khatanga, Lena, Kolyma, and Indigirka rivers. Water sampling was performed in August\u2013October 2015 and 2017. The DOC was determined by high-temperature combustion, and absorption coefficients and spectroscopic indices were calculated using the seawater absorbance obtained with spectrophotometric measurements. Kara and Laptev mixing zones were characterized by conservative DOC behavior, while the East Siberian sea waters showed nonconservative DOC distribution. Dominant DOM sources are discussed. The absorption coefficient aCDOM (350) in the East Siberian Sea was two-fold lower compared to Kara and Laptev seawaters. For the first time we report the DOC content in the Khatanga River of 802.6 \u00b5M based on the DOC in the Khatanga estuary.<\/jats:p>","DOI":"10.3390\/rs13061145","type":"journal-article","created":{"date-parts":[[2021,3,17]],"date-time":"2021-03-17T11:48:22Z","timestamp":1615981702000},"page":"1145","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":22,"title":["CDOM Optical Properties and DOC Content in the Largest Mixing Zones of the Siberian Shelf Seas"],"prefix":"10.3390","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5547-6693","authenticated-orcid":false,"given":"Anastasia N.","family":"Drozdova","sequence":"first","affiliation":[{"name":"Shirshov Institute of Oceanology, Russian Academy of Sciences, 117997 Moscow, Russia"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1798-2325","authenticated-orcid":false,"given":"Andrey A.","family":"Nedospasov","sequence":"additional","affiliation":[{"name":"Shirshov Institute of Oceanology, Russian Academy of Sciences, 117997 Moscow, Russia"}]},{"given":"Nikolay V.","family":"Lobus","sequence":"additional","affiliation":[{"name":"K.A.
