Chronological, geochemical and sedimentological data from a lake sediment record extracted from Lake L5 (Matias Lake) on Potter Peninsula, South Shetland Islands in 2011

The dataset comprises of lake site photos, data and multiproxy data from Lake L5 (aka Matias Lake), a small lake basin at 62.2450 S, 58.6655 W on Potter Peninsula, King George Island, South Shetland Islands. The data have been used to constrain deglaciation and glacier dynamics on Potter Peninsula. Data for the Lake L5 (Matias Lake) sediment record consist of downcore measurements of chronology, geochemistry, and sedimentology proxy data collected from the depocentre in November 2011. Data collected in this study were funded by: Centro de Investigaciones en Ciencias de la Tierra (CICTERRA), the Direccion Nacional del Antartico/Instituto Antartico Argentino (DNA/IAA) in the framework of the Project PICTA, 2011 - 0102, IAA and Geomorfologia y Geologia Glaciar del Archipielago James Ross e Islas Shetland del Sur, Sector Norte de la Peninsula Antartica, the Alfred Wegener Institute (AWI) research program Polar regions and Coasts in a changing Earth System (PACES II); IMCONet (FP7 IRSES, action no. 318718); the Natural Environment Research Council (NERC/BAS-CGS Grant no.81); the NERC/BAS science programmes CACHE-PEP: Natural climate variability - extending the Americas palaeoclimate transect through the Antarctic Peninsula to the pole and GRADES-QWAD: Quaternary West Antarctic Deglaciations.
