During Ocean Drilling Program (ODP) Leg 105, three sites (Sites 645 through 647) were drilled in Baffin Bay and the Labrador Sea to examine the tectonic evolution and the climatic and oceanic histories of this region. Biostratigraphic and magnetostratigraphic results vary at each site, while stratigraphic resolution depends on the limited abundance of marker species and the completeness of the paleomagnetic record. Because of the paucity of planktonic microfossils and the poor paleomagnetic record signatures, stratigraphic determinations at Site 645 often rely on defining minimum temporal constraints on specific samples or stratigraphic intervals. The completed stratigraphy indicates that the sedimentary sequence recovered at Site 645 is early Miocene to Holocene in age.The magnetostratigraphy and biostratigraphies are better defined at Sites 646 and 647 in the Labrador Sea. Site 646 generally contains a well-developed magnetostratigraphy and calcareous microfossil biostratigraphy. This biostratigraphy is ... : Supplement to: Baldauf, Jack G; Clement, Bradford M; Aksu, Ali E; de Vernal, Anne; Firth, John V; Hall, Frank R; Head, Martin J; Jarrard, Richard D; Kaminski, Michael Anthony; Lazarus, David B; Monjanel, Anne-Lise; Berggren, William A; Gradstein, Felix M; Knüttel, Stephen; Mudie, Peta J; Russell, Merlin D Jr (1989): Magnetostratigraphic and biostratigraphic synthesis of Ocean Drilling Program Leg 105: Labrador Sea and Baffin Bay.
