ANTARCTICA, EARTH - 2003 - The 2003 Antarctic ozone hole is the second largest ever observed, according to scientists from NASA, the US National Oceanic and Atmospheric Administration (NOAA), and the US Naval Research Laboratory (NRL). The Antarctic ozone hole is defined as thinning of the ozone layer over the continent to levels significantly below pre-1979 levels. Ozone blocks harmful ultraviolet rays. Loss of stratospheric ozone has been linked to skin cancer in humans and other adverse biological effects on plants and animals. The size of this year's Antarctic ozone hole reached 10.9 million square miles on 11 September, 2003, slightly larger than the North American continent, but slightly smaller than the largest ever recorded, on September 10, 2000, when it covered 11.5 million square miles. Last year the ozone hole was smaller, covering 8.1 million square miles. The image above was created with data from NASA's Earth Probe Total Ozone Mapping Spectrometer (TOMS). Blue represents the lowest ozone levels, while orange and red represent the highest - Photo: Geopix/NASA
