Amazon Shelf Holocene to Present Benthic Foraminifera (Tropical and Subtropical WSAOBIS, BRAZIL)
Entry ID: Amazon_Shelf_Benthic_Foraminifera

[ Get Data ]

Abstract: Benthic foraminifera of box core and piston core samples were collected from the Amazon middle to outer shelf. The assemblages and their taphonomic features confirmed a record of oceanographic changes from the early Holocene to the present. Foraminiferal data in conjunction with sedimentological, stratigraphic, seismic, and isotopic results point to three contrasting depositional environments. The ... View entire text
