West Antarctica experienced a significant ice-sheet retreat during LGM, manifested by isostatic rebound, continental uplift, and, potentially, the accumulation of freshwater masses in the subsurface. Nowadays, the Antarctic Peninsula (AP) undergoes extensive basal melting, supplying fresh water to the Southern Ocean. AP's nutrient-rich freshwater fluxes and uplift promote gas hydrate dissociation from the sub-seabed to the water column and potentially subsequent methane transformation to CO2. Dissolved CO2 in the seawater commonly forms bicarbonate and precipitate (i.e., removing carbon from the ocean). Alternatively, CO2 may stimulate water acidification, thereby adding carbon to the Southern Ocean's circulation. The interplay between ice-sheet melting,  isostatic rebound,  and methane transformation CO2 at AP is poorly understood. ICEFLAME aims to gain new insights into these processes, possibly contributing to the global carbon cycle.
