Short-term mass changes and retreat of the Ecology and Sphinx glacier system, King George Island, Antarctic Peninsula
Abstract This study investigated the mass balance, melting, near-surface ice thermal structure and meteorological conditions of the Ecology and Sphinx glacier system (ESGS), located on King George Island, Antarctic Peninsula. The study also analysed the role of climate change in glacial retreat of t...
