Calcareous nannofossil paleofluxes as proxy of pCO2 fluctuations during the Early Cretaceous

open access: yes, 2010
Calcareous nannoplankton is an excellent proxy for detecting present and paste surface water conditions, being extremely sensitive to changes in temperature, fertility, salinity and chemical conditions of the oceans.

The Miocene “Pteropod event” in the SW part of the Central Paratethys (Medvednica Mt., northern Croatia)

open access: yesGeologica Carpathica, 2017
Deep marine Miocene deposits exposed sporadically in the Medvednica Mt. (northern Croatia) comprise pelagic organisms such as coccolithophores, planktic foraminifera and pteropods.

Validation of Pedinocyclus and Quinquerhabdus, New Calcareous Nannoplankton Genera [PDF]

open access: yes, 2017
Validation of the names of these two calcareous nannoplankton genera is necessary because generic diagnosis was not given in Bukry and Bramlette (1969) and because a proposed new genus name, Leptodiscus, has been determined to be preoccupied by a ...

Living and fossil calcareous nannoplankton from the Australian sector of the Southern Ocean: Implications for Paleoceanography

open access: yes, 1998
This study documents the distribution of calcareous nannoplankton in the waters and surface sediments of the Australian Sector of the Southern Ocean, and applies the information to core samples from the region to infer past changes in the ocean between ...

Calcareous nannofossils biostratigraphy (Upper Bajocian – Lower Bathonian) of the Ravin du Bès section (Bas Auran, Subalpine Basin, SE France), evolutionary trends of Watznaueria barnesiae and new enigmatic morphotypes of genus Rucinolithus

open access: yes, 2008
A biostratigraphic and evolutionary study based of calcareous nannofossils was performed on the Ravin du Bès section (Bas Auran area, SE France), proposed as formal candidate of Global Boundary Stratotype Section and Point (GSSP) for the base of the ...

From shelf to abyss: Record of the Paleocene/Eocene-boundary in the Eastern Alps (Austria)

open access: yesGeologica Acta, 2009
In the Eastern Alps (Austria) several marine successions, which were deposited ranging from shallow shelf to bathyal slope and abyssal basin, provide detailed records across the Paleocene/Eocene-boundary.

Downsizing the pelagic carbonate factory: Impacts of calcareous nannoplankton evolution on carbonate burial over the past 17 million years

open access: yes, 2014
International audienceCenozoic deep-sea carbonates (“calcareous oozes”) are predominantly biogenic in origin and offer detailed records of the evolution of calcifying plankton groups, such as coccolithophores and foraminifera.

Volume calculation of Paleocene calcareous nannofossils

open access: yes, 2008
During the past decades, volume calculation of extant calcareous nannoplankton has been performed in order to convert coccolith fluxes data into carbonate export productivity.
