Lying between South America and the Antarctic Continent there are several 
groups of islands—South Georgia, the Sandwich Group, and the South Orkney and 
South Shetland Islands—which rise from a curved submarine ridge of less than 1,500 
fathoms in depth connecting the two continents, the two latter groups being separated
