Geochemical data (clay mineral, XRF-scanner and biomarker data) for core LC12 sediment record from Blaso, a large, epishelf lake in NW Greenland collected July-August 2017
GB/NERC/BAS/PDC/01667

Summary

Abstract:
The dataset comprises multi-proxy analyses of sediment core, LC12, extracted from Blaso, a large epishelf lake on the margin of 79 degree N Ice Shelf, NW Greenland in July-August 2017. The data are used to constrain ice shelf dynamics over the last ~8500 calibrated years before present (cal. years B.P., where present is A.D. 1950).
A 2 m-long sediment core was recovered with a UWITEC KOL 'Kolbenlot' percussion piston corer to a total sediment depth of 5.24.
Core LC12: 90 m water depth; 79.5948 degrees N, 22.44233 degrees E.
Geochemical data for the LC12 sediment records consists of clay mineral, XRF-scanner and biomarker data.
