Leg 202 Preliminary Report Southeast Pacific Paleoceanographic Transects 29 March – 30
More than 7 km of long and relatively continuous sediment sequences from 11 sites in the southeast and equatorial Pacific were recovered during Leg 202 for the study of the Earth’s climate and biogeochemical systems on scales that range from tectonic (millions of years) to orbital (tens to hundreds of thousands of years) and centennial to millennial (hundreds to thousands of years). These mater...
متن کامل10. Data Report: Major and Trace Element Data for Leg 202 Sites 1233 and 1234
The exchange of waters between the Pacific and the Southern Oceans occurs along the eastern boundary of the South Pacific. Because water masses of the Antarctic provide a connection among the world’s ocean basins, these water masses maintain the ability to influence changes in ocean circulation and climate (Lynch-Stieglitz et al., 1996). One of the primary goals of Ocean Drilling Program (ODP) ...
متن کاملLeg 210 Preliminary Report
Ocean Drilling Program Leg 210 was devoted to studying the history of rifting and postrift sedimentation in the Newfoundland–Iberia rift. Drilling was conducted in the Newfoundland Basin along a transect conjugate to previous drilling on the Iberia margin (Legs 149 and 173). This was the first time that deep-sea drilling has been conducted on both sides of a nonvolcanic rift in order to underst...
متن کامل34. Magnetostratigraphy of Upper Cenozoic Sediments from Leg 145, North Pacific Ocean
Paleomagnetic measurements were performed on whole cores and discrete samples from approximately 4 km of sediment recovered during Leg 145 of the Ocean Drilling Program. The obtained magnetic polarity sequences enabled the establishment of a chronostratigraphic framework from the middle Miocene (about 18.3 Ma) to the present. The quality of the magnetic record is related directly to the sedimen...
