Pedersenbreen冰川是位于北极新奥尔松小镇(Ny-lesund)附近的一条多温山谷冰川,该冰川从2004年开始被列为中国长期监测的两条冰川之一.利用2009年中国考察队员在Pedersenbreen冰川表面采集的GPS/GPR数据,结合挪威极地研究所出版的Svalbard地区A7(Kongsfiorden)片区地形图等高线重建了该冰川不同年份的冰川面积、体积等参数,分析了该冰川1936～1990～2009年的变化.分析发现,Pedersenbreen冰川从20世纪初小冰期结束以后,经历了一个明显的退缩,冰舌退缩了0.6km以上,体积减少了近13%,且在最近20年,出现加速消融的趋势.进一步分析发现,Pedersenbreen冰川的消融主要集中在冰川下游的冰舌位置,而在该冰川的上游,出现了积累,这一趋势与Svalbard地区同类型冰川表现一致,但随着全球变暖的加剧,近几年积累区面积已经大为减小.
The Pedersenbreen Glacier is a mountainous glacier located near the town of Ny-lesund in the Arctic and has been listed as one of two long-term monitored glaciers in China since 2004. Using the 2009 Chinese expedition team members Based on the GPS / GPR data collected on the surface of the Pedersenbreen Glacier, the glacier area and volume in different years of the glacier are reconstructed with the Contour Map of the Kongsfiorden A7 (Kongsfiorden) area published by the Norwegian Polar Institute. ~ 2009. The analysis found that the Pedersenbreen Glacier experienced a significant retreat after the end of the Little Ice Age in the early 20th century, with the ice tongue retreating more than 0.6km and its volume decreased by nearly 13%. In the recent 20 years, the glacier accelerated The further analysis shows that the melting of the Pedersenbreen glacier mainly concentrates in the position of the glacier in the lower glacier, and the accumulation in the upper reaches of the glacier is consistent with that of the glaciers of the same type in the Svalbard region. However, Warmer intensified in recent years accumulated area has been greatly reduced.
