  • Ice flow acceleration has played a crucial role in the rapid retreat of calving glaciers in Alaska, Greenland and Antarctica. High-frequency measurements of ice speed and basal water temperatures from a calving glacier in Patagonia show that changes in basal water pressure by a few per cent can significantly affect ice flow speed.

  • Glacier Perito Moreno, in the southern Patagonian Icefields, is now experiencing accelerated thinning, flow acceleration, and unprecedented frontal retreat, indicating the potential for buoyancy-driven retreat once it passes a subglacial ridge, according to observational data, bathymetric surveys, and satellite time series of surface elevation and velocity.

  • Synthetic aperture radar interferometry reveals that 19 Gt of ice is lost per year from glaciers in South America — mostly from Patagonia — contributing 0.04 mm annually to global sea-level rise.
