4 UNIVERSITY OF OSLO Impacts from glaciers on local and global sea level l Isostatic effects local - ice load - shrinking uplift/rebound l Fresh water flux mass balance/volume changes of land-based ice masses - direct effect on global mean sea level
5 UNIVERSITY OF OSLO Hva påvirker havnivået? l Termisk ekspansjon av havvannet l Landbaserte ismassers volumendring l Antarktis l Grønland l Lokale breer og iskapper l Grunnvann, permafrost, kunstig vannmagasinering
6 Globale havnivåendinger siste år

8 Global sea level changes last years (since LGM) BP ~10mm/y AD ~ 1.5 mm/y
9 Gjennomsnittlig globalt hanivå er beregnet til å stige 0.09 til 0.88 m innen 2100 (IPCC, 2001) (men med store regionale variasjoner!)

14 Bredekte områder utenom Grønland og Antarktis From Gregory et al. (2001)

20 Arctic cumulative volume change (from ACIA, 2005)
21 Arctic glaciers ~ 50 % of glaciers and ice caps outside Greenland and Antarctica General slightly negative but no increasing melt-trend trends from 1950ies to about 1990 Since late 1980ies/early 1990ies increased melting trend l Alaska: increasing melt rate: mid 50ies mid 1990ies ~ m/y mid 1990ies present ~ - 1,8 m/y l Canada: stable or slightly negative 1960 end 1980ies then increased melt rate l Svalbard: slightly negative since 1960ies end 1990ies - recent trend towards more melting after 2000 l Russian Arctic - slightly negative no annual mass balance data
22 Global cumulative net balance
23 Observationally based global estimate of mass balance period mm SLE a ± ± 0.42 Consensus estimate based on Ohmura (2004), Cogley (2005), Dyurgerov and Meier (2005) (compiled from Raper 2006) The above includes glaciers and ice caps in Greenland and Antarctica. NB- Large uncertainty of up to ca. ± 70 %

26 Increasing melt extent on the Greenland Ice Sheet Record melt extent in 2005 (Huff & Steffen, 2005)
27 Calving V/ V/ a = M a - M m - M c ± M b l Arctic glaciers/ice caps: 10 % to 50% of the ablation l Greenland: 40% to 60% of the total ablation l Ca. 90% of the mass loss from the Antarctic ice sheet l still calving is the term of the mass balance budget with the largest uncertainty
28 Calving from ice shelves

31 Processes that increase the ice flux l Increased sliding caused by more meltwater l Increased sliding caused by less back-pressure (iceshelf collaps and retreat)
32 Increased basal sliding l Zwally et al. (2002) has observed increased sliding in summertime, which correlates with surface melting Krabill et al. 2000
33 UNIVERSITY OF OSLO Feedback effect of surface melting on ice streams Ice velocities and calving rates tend to increase when more water is supplied to a glaciers' drainage system (e.g. Zwally et al., 2002). more surface melting increased sliding and calving surface lowering more surface melting
34 UNIVERSITY OF OSLO Increased sliding caused by less back-pressure l Larsen Ice shelf retreat triggered speed up of 6-8 times on glaciers upstream of the ice shelf (Scambos et al. 2003) l Jacobshavnbreen, Greenland shrinking retreating ice front doubling of speed (Thomas et al. 2002)
35 Larsen Ice Shelf collapse Landsat TM, MODIS Terra, Surging of upstream ice streams?
36 Potential sea level changes until year modified from recent trends?
37 UNIVERSITY OF OSLO l Study the current mass budget of selected target glaciers - the surface mass balance and the calving flux l Study subglacial processes; sliding/hydrology l Study the calving processes l Include the dynamics in modeling of future response l Predict future changes IPY GLACIODYN The dynamic response of Arctic glaciers to climate changes

42 UNIVERSITY OF OSLO Glacier mass balance modeling (ACIA, 2005) l Static approach l Surface mass balance (M a - M m ) energy balance modeling l Constant geometry l Constant iceberg calving
