Data report: High-resolution stable isotope stratigraphy of the late Middle Eocene at Site 1051, Blake Nose
MetadataShow full item record
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.
