Data sets

Permafrost-Region Lake-DOC version1 Database (PeRL-DOCv1) L. Stolpmann, C. Coch, A. Morgenstern, J. Boike, M. Fritz, U. Herzschuh, K. Stoof-Leichsenring, Y. Dvornikov, B. Heim, J. Lenz, A. Larsen, K. Walter Anthony, B. Jones, K. Frey, and G. Grosse

Short summary
Our new database summarizes DOC concentrations of 2167 water samples from 1833 lakes in permafrost regions across the Arctic to provide insights into linkages between DOC and environment. We found increasing lake DOC concentration with decreasing permafrost extent and higher DOC concentrations in boreal permafrost sites compared to tundra sites. Our study shows that DOC concentration depends on the environmental properties of a lake, especially permafrost extent, ecoregion, and vegetation.
