    Dataset from a paper submitted to Limnology and Oceanography Letters titled 'Accumulation of recalcitrant dissolved organic matter in aerobic aquatic systems'. Data include both experimental and observational data from a set of lakes just west of Kangerlussuaq, SW Greenland (67° N, 51° W). Experimental data were from incubations of lake water from several lakes that differ in salinity with microbes to examine the degradation of dissolved organic matter (DOM). The loss of DOM was followed for nearly a year and the results were fit to an exponential decline model. The observational data come from some of the same lakes but includes others in the region. These data include measurements of dissolved organic carbon (DOC), carbon stable and unstable isotopes (13C, 14C), optical properties (absorbance, SUVA, spectral slope) and specific conductivity. Other data include catchment characteristics for lakes in the region (lake and catchment area, altitude, maximum depth). Other data include profiles of dissolved oxygen and temperature for several of the lakes and the 14C dates.
