Description:
Data includes Grain Size and Loss-on-Ignition from two lakes (Black Hole and Ice Fall Lakes) in Graben Land, East Greenland, between Scoresby Sund and the Greenland Ice Sheet.  Raw core information is at the Limnological Research Center(LRC)in Minneapolis, MN as are 1/2 of the archive cores. Working cores are at the University of Cincinnati.

#       Abstract: The Holocene history of the Scoresby Sund region of East Greenland is partly recorded in lacustrine cores. Specifically, three lakes in Graben Land were cored in 2011. Cores recovered from two meltwater fed lakes distal to Vindue Gletscher, an outlet glacier of the Greenland Ice Sheet, have four primary units: fine and coarse silts, sands, and organic silt. Based on unit thickness, grain size and stratigraphic position, the fine silt (10 cm) is suggested to be of glacial origin and thus implies expansion of the ice sheet occurred by 500 cal yr. BP.  The coarse (< 1 cm) silt layers have larger grain sizes, have a slight organic component and occur at 1330, 1700 and 3300 cal yr. BP. These properties suggest a wind origin.  Sand units in the lakes have variable thickness and are tentatively suggested to be deposited by slush avalanches from surrounding slopes.  The remaining core is organic silt (10 cm) and locally can have diatoms. This unit represents the baseline lacustrine sedimentation. The fine silt is located at the top of the cores with the coarse silt and sand intermixed at various depths in the organic silt.  The oldest sediments recovered date to 4,700 BP. Separating among the various processes is necessary to faithfully reconstruct glacial history.
