Detecção de mudanças ambientais na Antártica através de dados de sensoriamento remoto e mapas históricos
Ice masses in the South Shetland Islands, Antarctica, are relatively thin and near or at the melting pressure point. They are, therefore, very sensitive t0 climatic variations. This work discusses glaciers retreat observed since 1950s in lhe Antarctic Specially Managed area(ASMA) of Admiralty Bay in...
