Antarctic researcher wearing a nose guard and sunblock to protect himself against the Sun. Sunlight contains high levels of UV (ultraviolet) radiation in Antarctica due to the presence of a hole in the ozone layer above the continent. Atmospheric ozone usually absorbs most of the UV light before it reaches the ground. Overexposure to UV light can lead to severe sunburn and an increased risk of skin cancer.
