East Antarctic Ice Sheet variability in the central Transantarctic Mountains since the mid Miocene
Published 2025-01-01“…Nonetheless, it remains uncertain whether the ice sheet is likely to undergo net loss due to amplified melting coupled with dynamic instabilities or whether such losses will be balanced, or even offset, by enhanced accumulation under a higher-precipitation regime. The glacial depositional record from the central Transantarctic Mountains (TAM) provides a robust geologic means to reconstruct the past behaviour of the East Antarctic Ice Sheet, including during periods thought to have been warmer than today, such as the mid-Pliocene Warm Period (<span class="inline-formula">∼3.3</span>–3.0 Ma). …”
