glacier mass balance data 2008 and 2009


1   Summary of the balance years

Preliminary mass balance values for the observation periods 2007/08 and 2008/09 have been reported now from about 100 glaciers worldwide. The mass balance statistics (Table 1) are calculated based on all reported values as well as on the data from the 30 reference glaciers in 9 mountain ranges (Table 2) with continuous observation series back to 1980.

The average mass balance of the glaciers with available long-term observation series around the world continues to be negative, with tentative figures indicating a further thickness reduction of 0.5 and 0.6 metres water equivalent (m w.e.) during the hydrological years 2008 and 2009, respectively. The new data continues the global trend in strong ice loss over the past few decades and brings the cumulative average thickness loss of the reference glaciers since 1980 at about 12.5 m w.e. (see Figures 1 and 2). All so far reported mass balance values for the two observation periods, given in Table 3, are tentative.

Please note, the latest update of mass balance data 2008 and 2009 will be available with the publication of the ‘Glacier Mass Balance Bulletin’ (GMBB) No. 11by end of the year 2011!
