Almost all Antarctic ice is compressed by fresh snowfall over a number of years, a process called firnification.
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.
