Palabras Clave: Concentración, Hielo marino, Radiómetro de Microonda Antarctica is one of the most inhospitable and inaccessible places on Earth, located to the South of 60° S. There, it is 90% of the ice of the planet and almost three quarters of the reserves of fresh water of the world. Antarctica regulates the climate through the ocean currents, winds and forming icebergs, the thickness and concentration of the ice. The study area corresponds to the Weddell and Bellingshausen seas. These areas are important because of the logistical operations undertaken to supply the Argentine Antarctic bases. The aim of this study was to compare the distribution of the ice field in the months of February and June by analyzing Microwave Radiometer (MWR) data, of the Argentine SAC-D Aquarius satellite, with optical and radar satellite images, and statistical limits of 40 years of absolute extreme values of sea ice data. MWR data was processed and correlated with data from sea ice concentrations published by various research centers, observing anomalies to be verified. It is expected that the information obtained will be relevant to the validation of the product and to compare as well as study sea ice concentrations estimated from MWR data.
