Last updated

Lacuna Island ( 65°31′S65°18′W / 65.517°S 65.300°W / -65.517; -65.300 Coordinates: 65°31′S65°18′W / 65.517°S 65.300°W / -65.517; -65.300 ) is a small island lying 8 nautical miles (15 km) east of Tula Point, the northern end of Renaud Island, in the Biscoe Islands, Antarctica. It was mapped from air photos obtained by Hunting Aerosurveys Ltd, 1956–57, and was so named by the UK Antarctic Place-Names Committee because the island lies in a lacuna (a gap) in the vertical air photos.

Geographic coordinate system Coordinate system

A geographic coordinate system is a coordinate system that enables every location on Earth to be specified by a set of numbers, letters or symbols. The coordinates are often chosen such that one of the numbers represents a vertical position and two or three of the numbers represent a horizontal position; alternatively, a geographic position may be expressed in a combined three-dimensional Cartesian vector. A common choice of coordinates is latitude, longitude and elevation. To specify a location on a plane requires a map projection.

Tula Point headland

Tula Point is a point forming the northeast extremity of Renaud Island in the Biscoe Islands. Alino Island lies 1 km south-southeast of the point.

Renaud Island

Renaud Island is an ice-covered island, 40 km (25 mi) long and from 6.4 to 16.1 km wide, lying between the Pitt Islands and Rabot Island in the Biscoe Islands of Antarctica. It is separated from Pitt Islands to the northeast by Mraka Sound, and from Lavoisier Island to the southwest by Pendleton Strait. Zubov Bay is a 2.5 mile bay that indents the east side of the island.
