Supplementary Data for "The history of Cenozoic carbonate flux in the Atlantic Ocean constrained by multiple regional carbonate compensation depth reconstructions"

The files on this site accompany the paper: Dutkiewicz, A. And Müller, R.D., in review, The history of Cenozoic carbonate flux in the Atlantic Ocean constrained by multiple regional carbonate compensation depth reconstructions, Geochemistry, Geophysics, Geosystems. There are two zipped file archives: 1) backtracked_sites.zip This archive contains two directories of backtrack site files, one for the North Atlantic and one for the South Atlantic. Each directory contains a set of files listing, by site: age(Ma), compacted_depth (observed)(mbsf), compacted_thickness (observed)(m), decompacted_thickness(m), decompacted_density(g/cm3), water_depth(m), tectonic_subsidence (since formation of crust)(m), decompacted_depth(mbsf) dynamic_topography(m) lithology The lithology classification follows the lithology classes defined in Muller et al. (2018). A second set of files contains: age(Ma), depth(mbsf), paleowaterdepth(m), dry_bulk_density(g/cm3), DLSR(m/my), carbonate(weight_%) CAR(mg/cm2/kyr) DLSR=decompacted linear sedimentation rate CAR=carbonate accumulation rate 2) regional_Cenozoic_carbonate_thickness_grids.zip This archive contains 3 folders with grids for modelled Cenozoic carbonate thicknesses for the South Atlantic, central North Atlantic and northern North Atlantic. They can be viewed with netcdf viewers like panoply, or plotted using the Generic Mapping Tools. The workflow for creating these grids can be found on GitHub: https://github.com/EarthByte/CarbonateSedimentThickness This site also contains a spreadsheet entitled "Dutkiewicz_Muller_G3_2022_model_data_summary.xlsx" It contains our model outputs including regional decompacted carbonate sediment volumes and thicknesses, depositional areas, carbonate carbon fluxes and carbonate compensation depths for the northern and central North Atlantic and South Atlantic. A video entitled "compacted_carb_thick_atlantic_66-0Ma.mp4" shows the Cenozoic evolution of carbonate sediment thickness in the Atlantic Ocean. References: Spasojevic, S., & Gurnis, M. (2012).

Unique functional diversity during early Cenozoic mammal radiation of North America

Mammals influence nearly all aspects of energy flow and habitat structure in modern terrestrial ecosystems. However, anthropogenic effects likely have altered mammalian community structure, raising the question of how past perturbations have done so. We use functional diversity to describe how the structure of North American mammal communities changes over the past 66 Ma, an interval spanning the rebound radiation following the K/Pg and several subsequent environmental disruptions including the PETM, the expansion of grassland, and the onset of Pleistocene glaciation. For 264 fossil communities, we examine three aspects of ecological function: functional evenness, functional richness, and functional divergence. Shifts in functional diversity are significantly related to major ecological and environmental transitions. All three measures of functional diversity increase immediately following the extinction of the non-avian dinosaurs, suggesting that high degrees of ecological disturbance can lead to synchronous responses both locally and continentally. Otherwise, the components of functional diversity respond differently to environmental changes and are decoupled for the last ~56 million years.
