Shifts in the Oligotrophic Warm Conditions of the Gulf of Mexico Over MIS‐6 to MIS‐1 Based on Planktonic Foraminifera Assemblages and Mg/Ca Ratios

open access: yesPaleoceanography and Paleoclimatology, Volume 40, Issue 1, January 2025.
Abstract Collected from the southwestern Gulf of Mexico (GoM), the marine piston Core RC10‐265 was used to reconstruct surface water masses, circulation and paleotemperature shifts at orbital scales over the last ∼180 ka. The chronology was constructed based on radiocarbon ages, planktonic foraminifera biostratigraphy and stable oxygen isotopes (δ18O).
