The islands
and archipelagos mentioned here are referred to as peri-Antarctic, rather
than sub-Antarctic, since many of them are similar in features despite
their location outside the Antarctic Convergence Zone.
The geographical
co-ordinates listed for the smaller islands are based upon the middle
of the island. It should be noted that historical dates given for sightings,
landings and winterings are the first recorded incidences. Sovereignty
over some of these islands is still disputed.
This list is presented
in an easterly order, from 0° longitude.
