Neogene paleoceanography of the eastern equatorial Pacific based on the radiolarian record of IODP drill sites off Costa Rica
(American Geophysical Union, 2017-03)
The Integrated Ocean Drilling Program (IODP) Expedition 344 drilled cores following a transect across the convergent margin off Costa Rica. Two of the five sites (U1381 and U1414) are the subject of the present study. Major ...

Validating NCAR-CCSM last glacial maximum sea surface temperature in the tropical and South Atlantic with proxy-data
(ELSEVIER SCIENCE BV, 2008)
Last Glacial Maximum simulated sea surface temperature from the Paleo-Climate version of the National Center for Atmospheric Research Coupled Climate Model (NCAR-CCSM) are compared with available reconstructions and ...
Late Campanian-Maastrichtian Kamptnerius magnificus acme in the South Atlantic section of the Southern Ocean, ODP Holes 690C and 700B
(Micropaleontology Press, 2016-09)
Coccolithophores are organisms with distribution largely controlled by temperature and availability of nutrients. For extinct calcareous nannofossils there are some uncertainties in assigning ecological preferences of taxa, ...
The calcareous nannofossil Sollasites falklandensis (Coccolithophyceae) and its biostratigraphic and palaeoceanographic importance in the Albian of the Austral Basin, Argentina
(Academic Press Ltd - Elsevier Science Ltd, 2011-12)
The presence of the calcareous nannofossil Sollasites falklandensis has been recorded in four exploration boreholes in the southeastern Austral Basin at levels assigned an Early to Middle Albian age. This study evaluates ...
Plateaus and jumps in the atmospheric radiocarbon record: Potential origin and value as global age markers for glacial-to-deglacial paleoceanography, a synthesis
(Copernicus Publications, 2020-12)
Changes in the geometry of ocean meridional overturning circulation (MOC) are crucial in controlling past changes of climate and the carbon inventory of the atmosphere. However, the accurate timing and global correlation ...
Postglacial North Pacific
(Elsevier, 2013-01-01)
Postglacial North Pacific paleoceanography is dominated by the ENSO system, which can acquire for centuries to thousands of years an El Niño-like or a La Niña-like dominant state. A La Niña-like (negative Pacific decadal ...
Environmental forcings of Paleogene Southern Ocean dinoflagellate biogeography
(American Geophysical Union, 2011-03-04)
Despite warm polar climates and low meridional temperature gradients, a number of different high-latitude plankton assemblages were, to varying extents, dominated by endemic species during most of the Paleogene. To better ...
