The inorganic geochemical record of the northwest Arabian Sea: a history of productivity variation over the last 400 k.y. from Sites 722 and 724

Abstract

Eolian dust input from the Arabian Peninsula and Somalia is characterized by the record of Ti/Al and Cr/Al. This dust record displays strong precessional periodicity (cycles at 25 k.y.) suggesting the Southwest Monsoon and associated winds play a key role in transporting terrigenous material from the land. -from Authors
