Map was generated from the coastline data set (except for other sets of line data such as political boundaries or rivers) of "World Data Bank II" with the addition of "World Vector Shoreline" (for the boundaries between Weddell Sea and Filchner Ice Shelf and between the same and Ronne Ice Shelf) retrieved from Online Coastline Extractor[NGDC] provided by National Geophysical Data Center (NGDC). Retrieved data set was processed with my own Java program and therefore no other resources such as data extracting software provided by NGDC were utilized. Adopted method is the azimuthal equidistant projection with projection center at the South Pole.
