      Full text of "Biostratigraphic And Geological Significance Of Planktonic Foraminifera Second Edition" See other formats. The Ontong Java Plateau (OJP) is the world's largest oceanic plateau and is presently the best and ideal place to do geochemical, geophysical, and geochronological investigations.

        During the last deglaciation period, climate changes in the northern and southern high-latitude regions show a pattern of so-called “bipolar seesaw” on millennial scale. Previous research interpreted that the weakening of the Atlantic Meridional Overturning Circulation (AMOC) and the associated north-south migration of the Intertropical Convergence Zone (ITCZ) influenced the. Planktonic foraminifera Foraminifera are separated into two types following their life strategy, namely, the benthic and the planktonic foraminifera. The benthic forms occur at all depths in.

      Benthic foraminifera in Pliocene samples indicate depths similar to water depths from which they were dredged, suggesting uplift, probably beginning in M Miocene and culminating in Pliocene) Fujita, K. & S. Kato ()- Distribution of gravel-sized empty tests of large benthic foraminifers as practical depositional indicators in tropical reef.   The cause of this event was the eruption of the Ontong Java Plateau in the western Pacific, wich led to a major increase in atmospheric pCO2 and ocean acidification. This event was characterized by the occurrence of organic-carbon-rich sediments on a global basis along with evidence for warming and dramatic change in nanoplankton assemblages.

dle Eocene Discoaster assemblage (Haq et al., ) as representing low- rather than middle-latitude climate. Our interpretation is in accord with the isotopic record from the Deep Sea Drilling Project (DSDP) site (Vergnaud-Grazzini, ); data on the early Paleocene climate is also based largely on somewhat meager isotopic records.

This is the first benthic delta18O stack composed of more than three records to extend beyond ka, and we use its improved signal quality to identify 24.

In Berger W., Kroenke, Mayer, L.A., et al., Proceedings of the Ocean Drilling Program, Scientific Results, Vol. College Station, TX (Ocean Drilling Program),   The use of tests produced by benthic foraminifera for Mg/Ca thermometry is inherently difficult because, except in very shallow water (e.g.

as in coral reef environments—see for example Raja et al. ), bottom water is cold, which means that the uptake of magnesium by the foraminifera is relatively small.

Furthermore during climate changes.
