Given in the paper are the results of geoelectric and remote sensing data processing of gas hydrate accumulations in the bottom structures of the West Antarctic region obtained during seasonal geophysical works of the 17th Ukrainian Antarctic Expedition, March 2012. Three anomalous zones of “gas-hydrate accumulation” type were found in the vicinity of the “Academician Vernadsky” UAS. It was obtained the parameters of two anomalously polarized gas hydrate reservoirs with the capacity from 100 to 500 m that lying on the continental slope of the South Shetland Islands. It is shown that the potential reserves of gas hydrates in the South Shetland Islands region is considerably (25–30 %) higher than previously calculated. That allows considering this region as one of the most promising gas hydrate deposit in Antarctica.
