We assessed colored dissolved organic matter (CDOM) absorption at 440 nm (a(440)CDOM) and absorption slope (S300\u2013500) in lakes using field sampling and optical remote sensing data for an area of 350 km2 in Central Yamal, Siberia. Applying a CDOM algorithm (ratio of green and red band reflectance) for two high spatial resolution multispectral GeoEye-1 and Worldview-2 satellite images, we were able to extrapolate the a(\u03bb)CDOM data from 18 lakes sampled in the field to 356 lakes in the study area (model R2 = 0.79). Values of a(440)CDOM in 356 lakes varied from 0.48 to 8.35 m\u22121 with a median of 1.43 m\u22121. This a(\u03bb)CDOM dataset was used to relate lake CDOM to 17 lake and lake catchment parameters derived from optical and radar remote sensing data and from digital elevation model analysis in order to establish the parameters controlling CDOM in lakes on the Yamal Peninsula. Regression tree model and boosted regression tree analysis showed that the activity of cryogenic processes (thermocirques) in the lake shores and lake water level were the two most important controls, explaining 48.4% and 28.4% of lake CDOM, respectively (R2 = 0.61). Activation of thermocirques led to a large input of terrestrial organic matter and sediments from catchments and thawed permafrost to lakes (n = 15, mean a(440)CDOM = 5.3 m\u22121). Large lakes on the floodplain with a connection to Mordy-Yakha River received more CDOM (n = 7, mean a(440)CDOM = 3.8 m\u22121) compared to lakes located on higher terraces.<\/jats:p>","DOI":"10.3390\/rs10020167","type":"journal-article","created":{"date-parts":[[2018,1,25]],"date-time":"2018-01-25T12:25:49Z","timestamp":1516883149000},"page":"167","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":20,"title":["Terrestrial CDOM in Lakes of Yamal Peninsula: Connection to Lake and Lake Catchment Properties"],"prefix":"10.3390","volume":"10","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3491-4487","authenticated-orcid":false,"given":"Yury","family":"Dvornikov","sequence":"first","affiliation":[{"name":"Earth Cryosphere Institute Tyumen Scientific Centre SB RAS, 625026 Tyumen, Russia"},{"name":"Alfred Wegener Institute Helmholtz Centre for Polar and Marine Research, 14473 Potsdam, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4634-6413","authenticated-orcid":false,"given":"Marina","family":"Leibman","sequence":"additional","affiliation":[{"name":"Earth Cryosphere Institute Tyumen Scientific Centre SB RAS, 625026 Tyumen, Russia"},{"name":"University of Tyumen, International Institute of Cryology and Cryosophy, 625003 Tyumen, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2614-9391","authenticated-orcid":false,"given":"Birgit","family":"Heim","sequence":"additional","affiliation":[{"name":"Alfred Wegener Institute Helmholtz Centre for Polar and Marine Research, 14473 Potsdam, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Annett","family":"Bartsch","sequence":"additional","affiliation":[{"name":"b.geos, 2100 Korneuburg, Austria"},{"name":"Zentralanstalt f\u00fcr Meteorologie und Geodynamik, 1190 Vienna, Austria"},{"name":"Austrian Polar Research Institute, 1090 Vienna, Austria"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ulrike","family":"Herzschuh","sequence":"additional","affiliation":[{"name":"Alfred Wegener Institute Helmholtz Centre for Polar and Marine Research, 14473 Potsdam, Germany"},{"name":"Institute of Earth and Environmental Sciences, University of Potsdam, 14469 Potsdam, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tatiana","family":"Skorospekhova","sequence":"additional","affiliation":[{"name":"Arctic and Antarctic Research Institute, 199397 Saint-Petersburg, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Irina","family":"Fedorova","sequence":"additional","affiliation":[{"name":"Institute of Earth Science, Saint-Petersburg State University, 199178 Saint-Petersburg, Russia"},{"name":"Kazan Federal University, 420008 Kazan, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8855-3483","authenticated-orcid":false,"given":"Artem","family":"Khomutov","sequence":"additional","affiliation":[{"name":"Earth Cryosphere Institute Tyumen Scientific Centre SB RAS, 625026 Tyumen, Russia"},{"name":"University of Tyumen, International Institute of Cryology and Cryosophy, 625003 Tyumen, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Barbara","family":"Widhalm","sequence":"additional","affiliation":[{"name":"Zentralanstalt f\u00fcr Meteorologie und Geodynamik, 1190 Vienna, Austria"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anatoly","family":"Gubarkov","sequence":"additional","affiliation":[{"name":"Tyumen Industrial University, 625000 Tyumen, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sebastian","family":"R\u00f6\u00dfler","sequence":"additional","affiliation":[{"name":"FIELAX, 27568 Bremerhaven, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2018,1,25]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1","DOI":"10.1016\/j.jhydrol.2004.03.028","article-title":"Development and validation of a global database of lakes, reservoirs and wetlands","volume":"296","author":"Lehner","year":"2004","journal-title":"J.
