This dataset contains analyses of sediment cores collected from multiple small lakes in the Thule region of northwest Greenland between 2012 and 2014, as well as complementary environmental data from two years of continuous lakewater temperature monitoring. Most sediment cores record the Holocene since regional deglaciation. Data include downcore analyses of magnetic susceptibility, grayscale reflectance, color and near IR reflectance, p-wave velocity and density at sub-centimeter resolution. This dataset also includes core site information, high-resolution images of sediment cores, radiocarbon ages on organic materials extracted from cores, and scanning x-ray fluorescence (XRF) data for one core. Temperature and light measurements through the water column of one study lake, covering approximately two years, are also included.
