| Accelerated melting of the Antarctic ice sheet (AIS) is one of the major contributors to global sea-level rise. To better constrain future climatic and environmental consequences, it is important to understand the history and mechanisms of AIS melting and associated sea-level changes. Since the Last Glacial Maximum, regional sea-level reconstructions are a critical component of these efforts to resolve past fluctuations in ice sheets and global sea-level.
Regional sea-level reconstructions have previously been attempted across the Skarvsnes area of Lützow-Holm Bay, East Antarctica (Takano et al., 2012; Verleyen et al., 2017). However, the results were not consistent, making it difficult to provide firm constraints on the past AIS in this region. Therefore, this study examines new evidence for relative sea-level changes from Lake Oyako-Ike, Skarvsnes, through sedimentological and microfossil (ostracod) analyses of a sediment core collected in 2017–2018 by the 59th Japanese Antarctic Research Expedition (JARE 59).
