We used in situ measurements and remote-sensing data sets to eval.ate the mass budgets of the l.mbert, Mel.or and Fisher Gl.ciers and the basal.mel.ing and freezing rates beneath their fl.wbands on the Amery Ice Shel.. Our findings show the l.mbert and Mel.or Gl.ciers upstream of the ANARE l.mbert Gl.cier Basin (l.B) traverse may have positive imbal.nces of 3.9±2.1 Gt a-1 and 2.1±2.4 Gt a-1, respectivel., whil. the Fisher Gl.cier is approximatel. in bal.nce. The upstream region as a whol. has a positive imbal.nce of 5.9±4.9 Gt a-1. The three same gl.ciers downstream of the ANARE l.B traverse l.ne are in negative imbal.nce, where the whol. downstream region has a negative imbal.nce of -8.5±5.8 Gt a-1. Overal. the mass budgets of the l.mbert, Mel.or, and Fisher Gl.ciers are cl.se to bal.ance, and the col.ective three-gl.cier system is al.o nearl. in bal.nce with a mass budget of -2.6±6.5 Gt a-1. The significant positive imbal.nces for the interior basin upstream of the ice-movement stations establ.shed in the earl. 1970s (Gl.l.ne) reported previousl. are possibl. due to an overestimate of the total.accumul.tion and an underestimate of the ice fl.x through the Gl.l.ne. The mean mel.ing rate is -23.0±3.5 m ice a-1 near the southern grounding l.ne, which decreases rapidl. downstream, and transitions to refreezing at around 300 km from the southern extremity of the Amery Ice Shel.. Freezing rates al.ng the fl.wbands are around 0.5±0.1 to 1.5±0.2 m ice a-1. The per-centage of ice l.st from the interior by basal.mel.ing beneath the fl.wbands is about 80%±5%. The total.basal.mel.ing and refreezing beneath the three fl.wbands is 50.3±7.5 Gt ice a-1 and 7.0±1.1 Gt ice a-1, respectivel.. We find a much l.rger total.basal.mel.ing and net mel.ing than the resul.s for the whol. Amery Ice Shel. derived from previous model.ng and oceanographic measurements.

利用现场观测与遥感数据对l.mbert,Mel.or和Fisher冰川的物质平衡及其在Amery冰架的底部融化与冻结状况进行了估算.结果表明,澳大利亚组织的l.mbert冰川盆地(l.B)考察路线的上游地区,l.mbert与Mel.or冰川分别为(3.9±2.1)和(2.1±2.4)Gt·a-1的正平衡,而Fisher冰川基本处于平衡状态.上游地区总的正平衡为(5.9±4.9)Gt·a-1.考察路线以下,3条冰川均处于负平衡,总的负平衡为(-8.5±5.8)Gt·a-1.整个l.mbert,Mel.or和Fisher冰川均接近于平衡状态.3条冰川总净平衡为(-2.6±6.5)Gt·a-1.前人认为Gl.(1970年代初澳大利亚在l.B建立的冰川运动观测点的连线)以上的内陆盆地处于显著正平衡,可能是因为过高地估算了总积累量,并低估了穿过Gl.的冰通量.靠近Amery冰架南端着地线,冰架底部的平均融化速率为(-23.0±3.5)m冰·a-1,向下游方向快速减小,并在距冰架最南端约300km处过渡为底部冻结.沿3条冰川在Amery冰架的冰流带(fl.wband),冻结速率约介于(0.5±0.1)^(1.5±0.2)m冰·a-1.由于冰流带底部的融化,流入冰架的内陆冰损失了大约80%±5%.3条冰流带底部总融化和总冻结分别为(50.3±7.5)和(7.0±1.1)Gt冰·a-1,这要比前人通过模拟和海洋观测估算的整个Amery冰架底部总融化和总冻结还要大很多.
