Amazon Shelf Holocene Present Benthic Foraminifera

OBIS Secretariat Open in mapper Explore occurrences

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.
