On the occurrence of the giant diatom Ethmodiscus rex in an 80-ka record from a deep-sea core, southeast of Sumatra, Indonesia : implications for tropical palaeoceanography

De Deckker, Patrick; Gingele, Franz

Environmental changes recognised in a 80-ka record obtained from a deep-sea core taken at a water depth of 2542 m offshore southeast Sumatra conclusively indicate, for the first time, that 'blooms' of the giant diatom Ethmodiscus rex occurred in the Indian Ocean during the last glacial period, with the largest numbers coinciding with the Last Glacial Maximum.
