Abstract
Accurate observations of surface mass balance are pivotal for assessing the Antarctic Ice Sheet mass balance and its link to climate dynamics. Studying regional changes in surface mass balance is challenging due to limited on-site observations and the susceptibility of measurements from snow pits and ice cores to localized disturbances. Satellite data and short-term localized measurements suggest no significant changes or a possible increase in surface mass balance across the East Antarctic Ice Sheet in recent decades, but these findings lack large-scale validation. Here we use observations from mass balance stakes to show a significant negative surface mass balance trend along the inland transect from Zhongshan Station to the Antarctic Ice Sheet summit (Dome A) during the period 2005–2020. The mean surface mass balance trend for the inland section over the 15-year period is −2.01 ± 0.37 kg m−2 yr–2, indicating a 35.5% decrease. This decrease is probably linked to enhanced zonal winds in the upper atmosphere and a deepened low-pressure system in the southern Indian Ocean. The former weakens meridional air transport to Antarctica, while the latter strengthens offshore winds over the study area, reducing onshore water vapour transport. These findings can be used to evaluate and improve regional climate models and refine estimates of contemporary Antarctic mass balance trends.

Extended Data Fig. 1 Map of the Zhongshan-Dome A traverse route and ERA5 precipitation trends (2005-2020).
a, A total of about 600 surface mass balance stakes were placed at 2 km intervals along the route, with annual surface snow accumulation measured from 2005-2020. Black scatter indicates areas of significant decreasing precipitation trends from linear regression (P < 0.05, two-sided), highlighted by yellow contours. b, Spatially varying annual-mean precipitation trends along the study transect (76°E-78°E, 70°S- 80°S), quantified using linear regression. The left axis shows the starting position, and the lower axis shows the ending position. The x = y axis represents the exact precipitation trend at each point. Stippling denotes trends significant at P < 0.05 (two-sided). c, 200 km annual-mean precipitation trends along the study transect. d, Significance levels of the 200 km running precipitation trends, with blue dashed line indicating P = 0.05.
Extended Data Fig. 2 The field operation scene for recording surface mass balance (SMB) stake heights.
Two personnel are required to measure the bamboo stakes’ height above the snow surface. One aligns a measuring rod vertically and parallel to the ice sheet, while the other, standing 5 meters away, records the height. Each stake is uniquely labeled with a metal plate showing its name and location, and GPS positions are recorded during each campaign. Credit: J. Deng.
