Persistent mass loss of Triangular Glacier, James Ross Island, north-eastern Antarctic Peninsula
Abstract The retreat rates of Triangular Glacier since 1979 and its mass changes during the period 2014/15–2019/20 indicate the sensitive response of small ice masses on the eastern side of the Antarctic Peninsula to air temperature evolution. This cirque glacier in the northern part of James Ross I...
