Since 1980, a 20% increase in river runoff has been observed in the Arctic system. As the discharges of the Ob, Yenisei, and Lena rivers are an important source of freshwater in the Kara and Laptev Seas, an increase in river discharge might have a significant impact on the upper ocean circulation. The fresh river water mixes with ocean water and forms a large freshened surface layer (FSL), which carries high loads of dissolved organic matter and suspended matter into the Arctic Ocean. Optically active material (e.g., phytoplankton and detrital matter) are spread out into plumes, which are evident in satellite data. Russian river signatures in the Kara and Laptev Seas are also evident in recent SMOS Sea Surface Salinity (SSS) Arctic products. In this study, we compare the new Arctic+ SSS products, produced at the Barcelona Expert Center, with the Ocean Color absorption coefficient of colored detrital matter (CDM) in the Kara and Laptev Seas for the period 2011\u20132019. The SSS and CDM are found to be strongly negatively correlated in the regions of freshwater influence, with regression coefficients between \u22120.72 and \u22120.91 in the studied period. Exploiting this linear correlation, we estimate the SSS back to 1998 using two techniques: one assuming that the relationship between the CDM and SSS varies regionally in the river-influenced areas, and another assuming that it does not. We use the 22-year time-series of reconstructed SSS to estimate the interannual variability of the extension of the FSL in the Kara and Laptev Seas as well as their freshwater content. For the Kara and Laptev Seas, we use 32 and 28 psu as reference salinities, and 26 and 24 psu isohalines as FSL boundaries, respectively. The average FSL extension in the Kara Sea is 2089\u20132611 km2, with a typical freshwater content of 11.84\u201314.02 km3. The Laptev Sea has a slightly higher mean FSL extension of 2320\u20132686 km2 and a freshwater content of 10.15\u201312.44 km3. The yearly mean freshwater content and extension of the FSL, computed from SMOS SSS and Optical data, is (as expected) found to co-vary with in situ measurements of river discharge from the Arctic Great Rivers Observatory database, demonstrating the potential of SMOS SSS to better monitor the river discharge changes in Eurasia and to understand the Arctic freshwater system during the ice-free season.<\/jats:p>","DOI":"10.3390\/rs13193828","type":"journal-article","created":{"date-parts":[[2021,9,27]],"date-time":"2021-09-27T22:16:38Z","timestamp":1632780998000},"page":"3828","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":15,"title":["Using Remotely Sensed Sea Surface Salinity and Colored Detrital Matter to Characterize Freshened Surface Layers in the Kara and Laptev Seas during the Ice-Free Season"],"prefix":"10.3390","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0748-7566","authenticated-orcid":false,"given":"Marta","family":"Umbert","sequence":"first","affiliation":[{"name":"Department of Physical and Technological Oceanography, Institut de Ci\u00e8ncies del Mar, CSIC, 08003 Barcelona, Spain"},{"name":"Barcelona Expert Center on Remote Sensing, CSIC-UPC, 08003 Barcelona, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0004-1964","authenticated-orcid":false,"given":"Carolina","family":"Gabarro","sequence":"additional","affiliation":[{"name":"Department of Physical and Technological Oceanography, Institut de Ci\u00e8ncies del Mar, CSIC, 08003 Barcelona, Spain"},{"name":"Barcelona Expert Center on Remote Sensing, CSIC-UPC, 08003 Barcelona, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3178-1554","authenticated-orcid":false,"given":"Estrella","family":"Olmedo","sequence":"additional","affiliation":[{"name":"Department of Physical and Technological Oceanography, Institut de Ci\u00e8ncies del Mar, CSIC, 08003 Barcelona, Spain"},{"name":"Barcelona Expert Center on Remote Sensing, CSIC-UPC, 08003 Barcelona, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8344-8326","authenticated-orcid":false,"given":"Rafael","family":"Gon\u00e7alves-Araujo","sequence":"additional","affiliation":[{"name":"National Institute of Aquatic Resources, Technical University of Denmark, DTU Aqua, 2800 Lyngby, Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sebastien","family":"Guimbard","sequence":"additional","affiliation":[{"name":"Ocean Scope, Plouzan\u00e9, 29280 Brest, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4749-0292","authenticated-orcid":false,"given":"Justino","family":"Martinez","sequence":"additional","affiliation":[{"name":"Department of Physical and Technological Oceanography, Institut de Ci\u00e8ncies del Mar, CSIC, 08003 Barcelona, Spain"},{"name":"Barcelona Expert Center on Remote Sensing, CSIC-UPC, 08003 Barcelona, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2021,9,24]]},"reference":[{"key":"ref_1","unstructured":"Poloczanska, E., Mintenbeck, K., Portner, H.O., Roberts, D., and Levin, L.A.
