Beryllium-10 exposure ages for Pope Glacier from a scoria cone 1.5 km west of Mount Murphy in the Amundsen Sea Embayment

The dataset contains 12 new Be-10 cosmogenic nuclide surface exposure ages. The samples were collected from a scoria cone 1.5 km west of Mt. Murphy an exposed volcanic edifice adjacent to Pope Glacier in the Amundsen Sea Embayment, Antarctica. Samples of erratic cobbles which showed evidence of transport by ice were collected over the 2015-2016 AmuNdsen Sea Embayment Exposure Dating (ANISEED) Field Season, prepared at the CosmIC laboratory, Imperial College London and measured for Be-10 at the Australian Nuclear Science and Technology Organisation. Beryllium-10 concentrations were measured by Accelerated Mass Spectrometry (AMS). Samples were measured to determine timing of deglaciation of two rock outcrops to better constrain the ice sheet lowering history of Pope Glacier during the Holocene. Study forms part of the wider International Thwaites Glacier Collaboration Project (ITGC). Samples were collected by Dr. Joanne Johnson and Dr. Stephen Roberts (British Antarctic Survey), supported by field assistants Alistair Docherty and Iain Rudkin. Sample preparation for 10Be measurement was carried out by Jonathan Adams - PhD candidate affiliated with British Antarctic Survey/ Imperial College London under the supervision of Dr. Dylan Rood - Imperial College London. AMS measurements of Beryllium-10 concentrations were performed by Dr. Klaus Wilcken - Australia''s Nuclear Science and Technology Organisation (ANSTO).

Statement

Be-10/Be-9 measurements are normalized to the KN-5-3 standard with an assumed ratio of 6.320 x 10^-12 ( (t1/2=1.36 Ma, Nishiizumi et al., 2007)

Scoria cone (CIN) Be samples and process blanks BLK140920A/B were prepared for analysis at the CosmIC labs, Imperial College London. AMS analysis was performed at ANSTO, Australia
