Data report: High-resolution stable isotope stratigraphy of the late Middle Eocene at Site 1051, Blake Nose
Abstract
The primary aim of the this investigation was to examine the stability
of subtropical sea-surface temperatures and reconstruct the surfaceto-
benthos thermal gradient. High-resolution stable isotopic analyses
(δ18O and δ13C) were conducted on late middle Eocene planktonic and
benthic foraminifers recovered from Hole 1051B, Blake Nose, western
North Atlantic. The sequence comprises a siliceous nannofossil and foraminifer
ooze, with well-preserved calcareous microfossils. Isotopic examination
was conducted on the mixed-layer dweller Morozovella
spinulosa and the benthic foraminifer Nuttalides truempyi at this subtropical
site.
