The Lambert Glacier Basin, over 10~6 km~2 in area,is a particular region because of its dis- tinct topography. A vast amount of stratigraphy observation of firn-core and snow一pit pro-files indicates that the visibale stratigraphic features are preserved well at relatively high accumulation sites. However, due to the effect of strong katabatic wind and microrelie(annualaccumulation varies greatly within a short distance, and as a result, several snow-profiles orseveral-vear stake data are necessarv in...

The Lambert Glacier Basin, over 10~6 km~2 in area,is a particular region because of its dis- tinct topography. A vast amount of stratigraphy observation of firn-core and snow一pit pro-files indicates that the visibale stratigraphic features are preserved well at relatively high accumulation sites. However, due to the effect of strong katabatic wind and microrelie(annualaccumulation varies greatly within a short distance, and as a result, several snow-profiles orseveral-vear stake data are necessarv in detennination of the aeeumulation rate at a site。 Thederived accumulation rate series from comparison of stratigraphy,δ~(18)Oand electric conduc-tivity profiles were verified by the early measurement result at a higher accumulation site。 Bycomparison with other regions ( such as Wilkes Land and Mizuho Plateau)in EastAntarctica,the most remarkable characteristic in this region is that the accumulation of localoceanic vapour and low aircurrent is that the accumulation rate is very low toward the coast,implying that the influence of local oceanic vapour and low aircurrent is not important.Theaeeumulation rate has an overall decrease trend for past 50 years in this region,strikinglycontrasting to the reported increase trend of recent decades for other regions in Antarctica.

近几年在Lambert冰川流域西部地区进行的大量雪芯、雪坑剖面观测表明,雪层的可见层位特征在积累速率较高时保存完好。但由于强烈下降风和微地形的影响,年积累量在短距离内变化较大,一个地点某一年份的积累量须由几个雪层剖面对比才能确定;若用花杆测量只能经几年观测获得其平均值。在积累量较高地点将雪层剖面、δ ̄(18)O和固体电导率剖面结合起来确定的积累速率序列由早期考察结果得以验证。与其它地区(如WilkesLand和Mizuho高原)相比,该地区最显著的特点是靠近海岸地带的积累速率很低,这意味着近海水汽和低气流对本区降水量的影响很小。近50年来积累速率的总趋势是减小,这与报道较多的其它地区近几十年来呈增加趋势明显不同。

The Lambert Glacier, feeding into the Amery Ice Shelf, is the largest ice stream in the East Antarctic ice sheet. Preliminary results from recent traverse along a route across its inland accumulation area show that the accumulation rate in this area is very low, not exceeding 150 kg/ (m ̄2 a) at most sites. The mean annual temperature ranges from -45℃ to -30℃. Average density of surface 2m snow is around 400 kg /m ̄3. Depth-hoar is seen at many sites with an elevation between 1830 and 2700 m. The surface...

The Lambert Glacier, feeding into the Amery Ice Shelf, is the largest ice stream in the East Antarctic ice sheet. Preliminary results from recent traverse along a route across its inland accumulation area show that the accumulation rate in this area is very low, not exceeding 150 kg/ (m ̄2 a) at most sites. The mean annual temperature ranges from -45℃ to -30℃. Average density of surface 2m snow is around 400 kg /m ̄3. Depth-hoar is seen at many sites with an elevation between 1830 and 2700 m. The surface velocity is generally within 20 m /a. Snow redistribution caused by strong katabatic-wind and sastrugi brings about an uncertainty in the annual-layer identification using 618O profile in low accumulation area.

Lambert冰川是Amery冰架的补给源,为东南极冰盖最大的一支冰流。近几年对该冰流源区的路线考察表明,该地区积累速率相当低,大部分观测点低于150kg/(m ̄2·a)。考察区域表面年平均温度为-45-30℃。表面2m雪层的平均密度在400kg/m ̄3左右变化。在1830-2700m海拔范围内的许多地点曾观测到深霜发育。表面运动速度基本上在20m/a以内。在低积累区,强烈的下降风和表面雪丘的发育使降雪重新堆积,导致应用稳定同位素比率剖面划分年层的可靠性下降。

Comparison of spatial distribution of the accumulation rate and its variability of past several decades in the Lambert Glacier basin with those in other areas of the Antarctic ice sheet indicates that variations of the accumulation rate both in space and in time are different in various areas on the ice sheet, so that it is difficult to accurately calculate the net accumulation and its change using the update limited data. The accuracy of estimates on iceberg calving and basal melting at present is relatively much lower. Therefor, the current state of mass balance of the ice sheet is still poorly known. Although the recent climatic warming may cause increase in precipitation, mass losses such as the iceberg calving and melting may increase too, and as a result, the ice sheet perhaps is in the negative mass balance. One practical way is to obtain the average state of mass balance over a certain period, say five or ten years, by means of extemsive and accurate remote sensing monitoring. It is necessary to combine the mass balance with the ice sheet dynamics and to develop the couple model of ice-ocean-atmosphere for accurate estimate of the mass balance state and its variability.

Lamben冰川流域与其它区域积累速率的分布特征和近几十年来的变化对比表明,南极冰盖积累速率空间和时间上的变化因地而异,用有限资料很难准确计算出净积累总量及其变化。目前边缘崩解和底部消融的估算准确性更差一些,因而不能很明确地评判物质平衡状态。近年气候变暖虽可能使降水量增加,但边缘崩解和冰盖融化等物质支出也必然会明显增大,从而使冰盖处于负平衡状态。通过广泛而精确的卫星遥感监测研究某一时段(如5a或10a时间)的物质平衡结果是较为可取的一种途径。准确地评判物质平衡变化趋势则需将物质平衡与冰体动力学结合起来,并建立冰-海-气耦合模型。
