Summary
Abstract: We evaluate phosphorus (P) and biogenic barium (bio-Ba) as nutrient burial and
export productivity indicators for the Late Cretaceous and early Paleogene,
combining these with calcium carbonate (CaCO3), organic carbon (C), and bulk
CaCO3 C isotopes (13C). Sample ages span 36-71Ma (~1 sample/0.5 m.y.) for a
depth transect of sites in the western North Atlantic (Blake Nose, Ocean
Drilling Program Leg 171B, Sites 1052, 1051, and 1050). We use a multitracer
approach including redox conditions to investigate export productivity
surrounding the global Paleocene 13C maximum (~57 Ma). Reducing conditions
render most of the bio-Ba record not useful for export productivity
interpretations. P and organic C records indicate that regional nutrient and
organic C burial were high at ~61 and ~69 Ma, and low during the Paleocene 13C
maximum, a time of proposed global high relative organic C burial. Observed
organic C burial changes at Blake Nose cannot explain this C isotope
excursion.
