Dynamics of the ice mass in Antarctica in the time of warming
The modern age of global warming affect the general state of the Antarctic ice sheet and its mass balance. Studies of the Southern polar region of the Earth during the International Geophysical Year (1957–1958) called the assumption of growth in the modern ice mass in East Antarctica. However, with...
