Marine Exploration History

Scientific surveys of the deep waters in the Indonesian seas from the 18th and 19th centuries (van Aken, 2005)



Multi-National Marine Exploration in Indonesian 1930 – 1980:  Dutch (Ekspedisi Snellius, Vening-Meinesz Expedition)  AS-LDEO (R/V Robert Conrad, R/V Vema, R/V Maurice Ewing)  AS-SIO (R/V Thomas Washington: SIO RAMA, INDOPAC; R/V Atlantis) 1980 – 2004:  Dutch-NIOZ (R/V Tyro: Snellius II Expedition)  France-Ifremer (R/V Coriolis: CORINDON, GEOINDON; R/V Jean Charcot: Krakatau; R/V Baruna Jaya; R/V Marion Dufresne)  German (R/V Sonne: GINCO I)  Japan-Jamstec (R/V Natsushima, R/V Yokosuka -Shinkai) Periode 2005 – Recent:  Multi-National (R/V Sonne: SeaCause I & II, SO-189; HMS Scott, R/V Roger Revelle; Marion Dufresne)

GEOMARIN III SURVEY FOCUS: 1. To accelerate the systematic geological mapping program, empasized on epicontinental and deep sea areas where natural resources (hydrocarbon, sulphide minerals and methane hydrate) are usually present. 2. Upgrading the status and knowledge of Indonesian hydrocarbon basins, particularly on the eastern Indonesian regions where geological exploration data are lacking. 3. Geotectonic studies on the tectonically active areas. 4. Mapping of the mineral placer deposits, particularly on the inner western Indonesian shelf.
