Almost all Antarctic ice is compressed by fresh snowfall over a number of years, a process called firnification.
A spokesman from Aberystwyth University said: "Almost all Antarctic ice forms over some decades as it is compressed by fresh overlying snowfall, a process called firnification. "However, water in these surface lakes freezes within one winter season, substantially altering the internal density and temperature of ice shelves.
Ice core evidence suggests that firnification rates on the ice cap have increased in recent years and were especially high in the 1995-2000 period, so it is unlikely that the observed thickening is due to a reduction in mean firn density.
