Resolution No.9 (1979): Repeat geomagnetic observation on islands

IAGA, considering the need for secular change data of the magnetic field from remote ocean areas and the possibility of achieving this by measurements at certain specified islands, urges the responsible authorities both to establish the following repeat stations and to re-observe at them at intervals of not more than 5 years: Atlantic Ocean: Ascencion, St. Helena, Cape Verde, Tristan da Cunha, Trindade Falkland, Gough, Bermuda; Pacific Ocean: Clipperton, Galapagos, Juan Fernandez, Line, Marquesas, Gambier, Austral, Marshalls, Carolines, Wake, Baker, Adak, Raoul, Auckland Island, Campbell, Snares, Coos, Fiji, Niue, Chatham, Bounty, Antipodes, Tonga, Solomons, Nauru, New Caledonia, New Hebrides; Indian Ocean: Heard, Diego Garcia, Seychelles, Maldives, Cocos, Christmas, Amsterdam Island.
