“…The mass-balance computations for Siachen Glacier show that in every year except one (1988–89), negative mass-balance values have been recorded since 1986. This finding is consistent with observations that indicate that Siachen Glacier has been receding during the past 5 years, in conformity with the current trend of general retreat of all Himalayan glaciers (Raina and others, 1977; Kulkarni, 1992). Higher mean air temperatures and a fairly continuous trend of negative values of mass balance indicate a period of warmer climate and excessive runoff and ablation during the study period.…”

ABSTRACT. The hyd rological method is used to compute the m ass ba la nce ofSiachen Gl acier in th e Nubra Valley, K a rakora m Him a laya, India. The m ethod was chosen because of its suitability in rugged terra in. Analysis of precipitati on ? ata from th e glacier as a ~unc tion of altitude shows a power-law rel ationship. Accumulal10n eStimates based on thls relati onship show good ag reem ent with th e recorded precipitati on.

“…Though temperate glacial mass-balance change is one of the best indicators of climate change (Oerlemans, 2001;Vincent and others, 2004;Ohmura and others, 2007), the paucity of mass- balance data in the Himalaya makes it difficult to obtain a coherent picture of regional climate-change impacts in this region. In the Indian Himalaya the first mass-balance study started on Gara Glacier, Himachal Pradesh, in September 1974 (Raina and others, 1977) and ended in 1983 (Dobhal and others, 2008). According to Dyurgerov and Meier (2005), eight glaciers in the Indian Himalaya were surveyed for mass balance for at least 1 year during the 1980s.…”

From balance to imbalance: a shift in the dynamic behaviour of Chhota Shigri glacier, western Himalaya, India

International audienceMass-balance and dynamic behaviour of Chhota Shigri Glacier have been investigated between 2002 and 2010 and compared to data collected in 1987/1989. During the period 2002/2010, the glacier experienced a negative glacier-wide mass balance of -0.67 ± 0.40 m/a w.e. Between 2003 and 2010, elevation and ice flow velocities are slowly decreasing in the ablation area leading to a 24 to 37% reduction in ice fluxes, an expected response of the glacier dynamics to its recent negative mass balances. The reduced ice fluxes still remain far larger than the balance fluxes calculated from the year 2002 to 2010 average surface mass balances. Therefore, further slow down, thinning and terminus retreat of Chhota Shigri Glacier are expected over the next years. Conversely, the 2003/2004 ice fluxes are in good agreement with ice fluxes calculated assuming that the glacier-wide mass balance is zero. Given the limited velocity change between 1987/1989 and 2003/2004 and the small terminus change between 1988 and 2010, we suggest that the glacier has experienced a period of near zero or slightly positive mass balance in the 1990s, before shifting to a strong imbalance in the 21st century. This result challenges the generally accepted idea that glaciers of Western Himalaya have been shrinking rapidly for the last decades
