A first approach to Bioclimatology and Biogeography of the Antartic is carried out establishing the diagnostic parameters and indices of thermotypes, chionotypes (ombrotypes) and continentality existing in the study area following the Rivas-Martínez et al. (2011) proposal. It is also defined a new bioclimatic variant called Semipolar antarctic bioclimatic variant (sepoa).
