Article
A composite late Maastrichtian (65.5 to 68.5 Ma) marine osmium (Os) isotope record, based on samples from the Southern Ocean (ODP Site 690), the Tropical Pacific Ocean (DSDP Site 577), the South Atlantic (DSDP Site 525) and the paleo-Tethys Ocean demonstrates that subaerially exposed pelagic carbonates can record seawater Os isotope variations with...

Article
Variations in the marine Os isotope record have been reconstructed based on more than 150 analyses of sediments from 4 locations: the South Atlantic (DSDP 525); the Southern Ocean (ODP 690C); the Equatorial Pacific (DSDP 577) and the Tethys (Bottaccione Section in Gubbio, Italy). All records show 187Os/188Os values close to 0.6 throughout most of m...
Article
Analyses of Os concentrations and ^{187}Os/^{188}Os ratios performed on bulk sediment samples from ODP 690C in the Weddell Sea yield the highest resolution marine Os isotope record available for the Maastrichtian. Comparison of this record to coeval data from Shatsky Rise (DSDP 577) and Walvis Ridge (DSDP 525) suggests three insights on the use of...
