Data report: planktonic and benthic foraminifers from IODP Hole U1322B1

Qianyu Li,2,3 Rong Xiang,4 and Fan Zheng4


Analyses of planktonic and benthic foraminifers in 141 samples from Integrated Ocean Drilling Program Hole U1322B reveal some distinct distribution patterns relating to climate and sea level changes in the northern Gulf of Mexico region. The sediment section is divided into planktonic foraminifer Zone Z, which features Globorotalia menardii, and Subzones Y1–Y5, which do not. Several benthic foraminifer assemblages show repeated occurrences, indicating waxing and waning of favorable environments for dominant species in marine isotope Stages 1–4.
