Ages are given for the mid-year point. E.g. melt values assigned # to 2006 are an average taken from ~July 2005 to ~June 2006. Data are given as annual averages from the top of the core back to 1807 AD. # Age control back to 1807 is annually-defined based on annual cycles of nss-SO4. Beyond 1807 the age control is derived from the JRI-1 # age scale (Mulvaney et al 2012, Nature), and data are given only as 11-year moving averages owing to the greater annual age uncertainty # in this portion of the record. # # Deuterium isotope data can be converted to temperature at this site using a temperature dependence of 6.4 per degC-1 (Abram et al.,2011, JGR) # See also the Supplementary information provided in Mulvaney et al 2012, Nature, for the full Holocene deuterium isotope data for the JRI ice core # (http://www.nature.com/nature/journal/v489/n7414/full/nature11391.html) # # #-------------------- # Publication # Authors: Nerilie J.

A key driver of ice loss is summer melting; however, it is not usually possible to specifically reconstruct the summer conditions that are critical for determining ice melt in Antarctic. Here we reconstruct changes in ice-melt intensity and mean temperature on the northern Antarctic Peninsula since AD 1000 based on the identification of visible melt layers in the James Ross Island ice core and local mean annual temperature estimates from the deuterium content of the ice. During the past millennium, the coolest conditions and lowest melt occurred from about AD 1410 to 1460, when mean temperature was 1.6C lower than that of 1981-2000. Since the late 1400s, there has been a nearly tenfold increase in melt intensity from 0.5 to 4.9%. The warming has occurred in progressive phases since about AD 1460, but intensification of melt is nonlinear, and has largely occurred since the mid-twentieth century. Summer melting is now at a level that is unprecedented over the past 1,000 years. We conclude that ice on the Antarctic Peninsula is now particularly susceptible to rapid increases in melting and loss in response to relatively small increases in mean temperature. #
