High resolution Eocene records of CaCO3 concentrations were calculated, by regression, using sediment physical property data and measurements of sediment CaCO3 content. We developed an astronomically
Natural gamma radiation (NGR) data in the ~0.1 to 3.0 MeV range were measured using eight custom-designed sodium iodide (thallium) [NaI(Tl)] detectors arranged along the core measurement axis at 20 cm
