Environmental Woes of Tierra del Fuego -- Ozone Depletion

Cpl. Adrian Silva of the Argentine Air Force peers through protective lenses to note the position of the sun. Silva aligns a Dobson Spectrometer to measure the amount of ozone above Tierra del Fuego from an Argentine meteorological agency station in Ushuaia. Fed by decades of chlorofluorocarbon emissions, the thin spot in the upper atmosphere has grown to the size of the ice cap itself. Normally showering only Antarctica with stronger ultraviolet rays, the irregularly-shaped hole nicks Tierra del Fuego a few days each year.
