SUMMARY:Are Karakoram glacier surges linked with climate? - Duncan Quincey
  (University of Leeds)
DTSTART:20131127T163000Z
DTEND:20131127T173000Z
UID:TALK47531@talks.cam.ac.uk
CONTACT:Poul Christoffersen
DESCRIPTION:Glaciers in the Karakoram are of particular current interest b
 ecause many are in balance or are gaining mass\, and the majority have eit
 her stable terminus positions or are advancing. A number of studies have c
 ited recent (decadal) climatic patterns as being responsible for this anom
 alous behaviour\, but the picture is somewhat complicated by the large num
 ber of surging glaciers in the region\, about which little is known. This 
 talk will present remotely sensed data that demonstrate glacier velocities
  can reach as high as 5 km/yr during a surge and that surge return periods
  may be as short as two decades. Such data can help to shed light on glaci
 er thermal conditions\, the processes that trigger surges in this region\,
  and how their characteristics may change in different climatic conditions
 . Better knowledge of Karakoram surges is critical if accurate assessments
  of the mass balance of western Himalayan glaciers are to be made.
