ギルバート諸島
The Gilbert Islands (sometimes also known as "Kingsmill Islands") are a chain of sixteen atolls and coral islands in the western Pacific Ocean. They are part of Remote Oceania, and traditionally part of the Micronesia subregion of Oceania. The Gilbert Islands are the main part of what is now the Republic of Kiribati ("Kiribati" is the Gilbertese rendition of "Gilberts") The atolls of the Gilbert Islands are arranged in an approximate north-to-south line. Geographically, the equator is the dividing line between the northern Gilbert Islands and the southern Gilbert Islands. South of the Gilbert Islands lie the Ellice Islands (now called Tuvalu), which were previously politically connected with them. The Ellice Islands comprise three reef islands and six true atolls, spread out between the latitude of 5° to 10° south and longitude of 176° to 180°, west of the International Date Line. The Ellice Islands are midway between Hawaii and Australia, and they, too, lie in the Polynesia subregion of Oceania.
