英文摘要	The directions of strong winds are important for the distribution of marine salt spray, rock weathering, lake chemistry and the distribution of vegetation in Bunger Hills, a coastal ice-free oasis in East Antarctica. Present-day strong winds (> 10 m s(-1)) dominantly blow from 118 +/- 21 degrees true (degrees T; +/- 1 SD). Orientated tafoni (weathering pits) might form in bedrock surfaces by salt and ice crystallization, thermal stress and saltating sand particles, recording the orientation of a strongly directional wind field since the last deglaciation, which commenced > 30 000 years ago. The orientations of these tafoni, at 101 +/- 18 degrees T for 686 measurements at 28 sites, are indistinguishable from the direction of modern-day strong winds (> 10 m s(-1)), indicating that the orientation of the slope of the ice sheet has been stable throughout the last 10 000 years during the Holocene.
