[Foraminiferal radiocarbon- MAZ-1E-04] - Radiocarbon measurements from planktic and benthic foraminifera in the eastern Pacific during the last deglaciation determined from core MAZ-1E-04 collected on cruise MAZ-I aboard the R/V El Puma in April 2015 (Glacial-Interglacial Changes in Oxygen Minimum Zones Using Deep-Dwelling, Low-Oxygen Planktic Foraminifera)

Listed in Biological and Chemical Oceanography Data Management Office (BCO-DMO) ERDDAP

The structure and drivers of oxygen minimum zone (OMZ) evolution in the Eastern Tropical North Pacific (ETNP) are investigated from ~20.7-10 ka using a multi-proxy from core MAZ-1E-04 (22°54.29'N, 106°54.59'W; 1463 m depth).

Description

Understanding how OMZ vertical structure changed during past glacial/interglacial cycles will help elucidate the drivers and patterns of OMZ expansion/contraction on longer timescales. Here, radiocarbon measurements from planktic and benthic foraminifera from core MAZ-1E-04 collected on cruise MAZ-I aboard the R/V El Puma in April 2015 are used to construct an age model and calculate ventilation ages.

Universidad Nacional Autónoma de México financed ship time and M. Alejandro Rodríguez Ramírez directed the oceanographic campaign to retrieve the core.
