Abstract

Nearly three decades of stable isotope ratios and surface mass balance (SMB) data from eight shallow firn cores retrieved at Fimbul Ice Shelf, East Antarctica, in the Austral summers 2009-2011 have been investigated. An additional longer core drilled in 2000/2001 extends the series back to the early eighteenth century. Isotope ratios and SMB from the stacked record of all cores were also related to instrumental temperature data from Neumayer Station on Ekström Ice Shelf. Since the second half of the twentieth century, the SMB shows a statistically significant negative trend, whereas the δ

KEY POINTS: Mass balance and stable oxygen isotope ratios from shallow firn coresDecreasing trend in surface mass balance, no trend in stable isotopesNegative correlation between SAM and SMB.

Keywords: Fimbul Ice Shelf; SAM; stable isotopes; temporal trends
