This paper reports the results of trial measurements of the concentration of cosmogenic Cl-36 in an ice core recovered from Dome Fuji Station, Antarctica. Ten ice samples were extracted from depths corresponding to the Last Glacial Maximum and the early Holocene, with each sample comprising similar to 150 g for a core length of 0.5 m (similar to 30-40 yr resolution). Analyses of Cl-36 concentrations by accelerator mass spectrometry were successfully performed within 10% precision, even for samples with low Cl-36/Cl values (similar to 3 x 10(-14)). The average Cl-36 concentrations were 16 x 10(3) atoms g(-1) for the Last Glacial Maximum, and 7 x 10(3) atoms g(-1) for the early Holocene. The apparent Cl-36 depositional flux at Dome Fuji Station during these periods was estimated to be approximately 2.5-3.5 x 10(4) atoms cm(-2) yr(-1). (C) 2009 Elsevier B.V. All rights reserved.
