The study includes ground-based data of surface mass balance calculations to assess the input of climate change on the ice sheet health. The study covers an approximately 471 km² area of the ice sheet that lies in between the Dålk and Polarårboken glaciers, Larsemann Hills, Prince Elizabeth, East Antarctica. Snow accumulation/ablation data is collected from 13 stake networks and 06 single stakes installed on the ice sheet. The monitored area is extrapolated on the basis of elevation and glaciological parameters using ArcGIS 10.8.1. The exposed height and precise locations of stakes have been recorded using DGPS and compared with the preceeding year's datasets. The annual measure accumulation/ablation data is processed in ArcGIS for the estimation of surface mass balance since 2018. The accumulation/ablation rate of the ice sheet is not uniform and influenced by the meteorological parameters i.e. temperature, precipitation and wind speed. The values of net surface mass balance are 0.027 Gt yr⁻¹, 0.088 Gt yr⁻¹, 0.044 Gt yr⁻¹, and 0.026 Gt yr⁻¹ since 2018 to 2021 respectively.

该研究包括表面质量平衡计算的地面数据，以评估气候变化对冰盖健康的影响。该研究覆盖了南极洲东部伊丽莎白王子城拉斯曼山的Dålk冰川和Polarårboken冰川之间约 471 km ²的冰盖区域。积雪/消融数据是从冰盖上安装的 13 个桩网络和 06 个单桩收集的。监测区域是使用 ArcGIS 10.8.1 根据高程和冰川参数推断的。使用 DGPS 记录了木桩的暴露高度和精确位置，并与前一年的数据集进行了比较。自2018年以来，每年的测量积累/消融数据在ArcGIS中进行处理，用于估算地表物质平衡。冰盖的积累/消融速率并不均匀，并且受到气温、降水和风速等气象参数的影响。2018年至2021年，净表面质量平衡值分别为0.027 Gt yr ^-1、0.088 Gt yr ^-1、0.044 Gt yr ^-1和0.026 Gt yr ^{-1 。}
