South Tarawa located in/on physical feature Tarawa
Geography
South Tarawa is a string of islets on the atoll of Tarawa, between the Tarawa Lagoon to the north, with a maximum depth of 25 metres (82 ft), and the Pacific Ocean to the south, with a depth of up to 4,000 metres (13,000 ft). The island has been built from sediments from the lagoon.The process of soil accumulation is driven by the dominant easterly trade winds and can be reversed during extended periods of westerly winds during El Niño–Southern Oscillations.These islets are now joined by causeways, forming one long islet on the reef along the southern side of the Tarawa Lagoon. Most of South Tarawa is less than 3 metres (9.8 feet) above sea level with an average width of only 450 metres (1,480 feet).
