Abstract
This study utilizes early 20th-century aerial photographs of East Antarctica to analyze glacier changes since the 1930s. In Lützow-Holm Bay, constant ice surface elevations were observed, indicating weakening land-fast sea ice. Along the Kemp, Mac Robertson, and Ingrid Christensen Coasts, moderate long-term glacier thickening was observed, with decadal variability. These long-term changes correlate with snowfall trends since 1940, suggesting that recent ice growth is part of a century-long trend.
