Marakei
Marakei is a small atoll in the North Gilbert Islands. It consists of a central lagoon with numerous deep basins, surrounded by two large islands separated by two narrow channels. The atoll covers approximately.
Geography
Marakei's total land area is. A 26-kilometre road circles the island. Its length, from the airport, across the lagoon to Teraereke at the island's southern portion, is. Its greatest width is at the village of Rawannawi, and narrowest width at Temotu on the island's western side. It is one of only two islands in Kiribati that encircles its lagoon. The Marakei lagoon contains salt water and is deep in some areas, but not tidal. Two narrow channels, Baretoa Pass and Raweta Pass, link the lagoon with the sea and are not navigable at low tide.Rawata Pass was the location of an obstruction in 1912 after an inter-village conflict.
Environmental issues
The construction of causeways caused a significant reduction in the flushing of the lagoon, reducing the water's oxygen levels so that fish are no longer found in it. Erosion and accretion along the shoreline has been linked to aggregate mining, and land reclamation and causeway construction are believed to have changed the currents along the shoreline.Villages
