Marotiri (Austral Islands)
Southern rock of Marotiri
Marotiri or Bass Rocks

Marotiri is a group of four uninhabited volcanic rocks protruding from the sea (and several submerged rocks), forming the southeastern end of the Austral Islands of French Polynesia. Marotiri is located at 27°55′00″S 143°26′00″W / 27.9166667°S 143.4333333°W / -27.9166667; -143.4333333. The closest island is Rapa Iti, 75 km further northwest, but separated from it by an ocean depth of more than 1,500 meters.[1] The rocks are part of the municipality of Rapa.

The climate is wet temperate. The rocks are almost devoid of vegetation. They are important as a seabird rookery. The waters around the rocks abound in fish.

The rocks emerge from a submarine platform 100 meters deep and 5 km in diameter. They lie at a distance between 1.5 and 3 km from one another. The total land area is 43,100 m², which is broken down as follows by the individual rocks:

Rock Area
(m²)
Northern Rock 5,800
Central Rock 1,800
Southern Rock 22,400
Western Rock 13,100
Marotiri 43,100

The southern rock is the largest, and with a height of 113 meters the highest.

Marotiri is also known as Bass Rocks (Îlots de Bass in French),[2] maybe according to the name of the European explorer George Bass.
