Brazilian Antarctica
Brazilian Antarctica (Portuguese: Antártida Brasileira or Antártica Brasileira) is the Antarctic territory south of 60°S, and from 28°W to 53°W, proposed as a "zone of interest" by geopolitical scholar Therezinha de Castro. While the substance of that designation has never been precisely defined, it does not formally contradict the Argentine and British claims geographically overlapping with that zone (the zone shares a border but does not overlap with the Chilean Antarctic Territory to its west).
