2  Description
  White Island, part of the McMurdo volcanic complex, is situated approximately 20 km south‑east of the edge of the McMurdo Ice Shelf and 25 km south‑east of Hut Point, the location of McMurdo Station (United States of America) and Scott Base (New Zealand) on Ross Island. The roughly triangular island is approximately 30 km long and 15 km wide at its maximum, and rises to a maximum elevation of 762 m in several locations. The northern and western shores of White Island descend steeply, with water depths of 600 m occurring within 5 km of the island.
  White Island is predominantly ice‑covered with most of the rock outcrops being in the north, and is completely surrounded by permanent shelf ice, between 10 m and 100 m in thickness, of the McMurdo Ice Shelf and Ross Ice Shelf. Black Island is situated 2.5 km west of White Island, separated by the shelf ice of White Strait.
  The ASPA includes 142 km2 of the shelf ice and open‑water cracks of both the Ross Ice Shelf and McMurdo Ice Shelf up to 5 km offshore north‑east, north and west from the White Island coast. The north‑eastern boundary extends from the north‑eastern coast of Cape Spencer‑Smith (167° 32 42 E, 78° 00 43 S) 5 km due east to 167° 46 37 E, 78° 00 43 S. The boundary then extends north‑west, and follows a line parallel to, and 5 km from, the coast, around Cape Spencer‑Smith and then heading south‑west to 167° 00 00 E, 78° 05 00 S. The boundary then extends due south for 7.8 km to 167° 00 00 E, 78° 09 12 S, and then 1.5 km east to the southern‑most significant outcrop of rock on the western coast of White Island (167° 05 00 E, 78° 09 12 S). The boundary then extends northwards, following the coastline around Cape Spencer‑Smith to the north‑eastern limit of the ASPA.
  The White Island coast is distinguished by a change in surface slope where the transition between the floating ice shelf and land occurs: the transition is in some places gradual and indistinct, and the exact position of the coast is not precisely known. For this reason the coastal (generally east) boundary of the ASPA is considered to follow the line of the coast as evidenced by a surface elevation rise towards the land of 2 m above the average elevation of the adjacent McMurdo Ice Shelf.
