Abstract

• Larsen-C ice shelf (LCIS) (Figure 1) à largest ice shelf on the Antarctic Peninsula (AP)
• Eastern AP unstable (Table 1)
• Current stability uncertain

• Stable oxygen (δ18O) and hydrogen (δ2H) isotopes in firn and ice provide climactic information
• Seasonality, annual accumulation, large-scale climactic modes
• Underutilized in firn

• Idealized sampling rates in firn have not been investigated across the LCIS
• Clear identification of sampling rates could provide insight for future firn core investigations
