1. What is the geographical definition?Physiographic region north of Antarctica, between approx. 46° and 60° South latitude
2. What is the oceanographic boundary?Located north of the Antarctic Convergence, a zone of significant marine productivity
3. What are the Subantarctic Islands and where are they located?They are islands just north of Antarctica, between about 46° and 60° south latitude. They are spread across the Atlantic, Indian, and Pacific Oceans.
4. Why do the Subantarctic Islands have glaciers even though they are not part of Antarctica?The islands stay very cold, so they can keep glaciers. These glaciers are called Subantarctic glaciers, different from the big ice sheets on the continent.

Physiographic Region: An area defined by its distinct geological and landform characteristics.
Antarctic Convergence: The oceanic boundary where cold Antarctic waters meet warmer subantarctic waters, creating a zone of high biological activity.
Biodiversity Hotspot: A region with an exceptionally high number of different plant and animal species, often facing significant threats.
Invasive Species: Non-native organisms that can outcompete or harm native species and ecosystems.
