Description
Summary:The primary aim of the this investigation was to examine the stability of subtropical sea-surface temperatures and reconstruct the surface-to-benthos thermal gradient. High-resolution stable isotopic analyses (18O and 13C) 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.
