Vertical fluxes of coccolithophores and foraminifera and their contributions to CaCO3 flux off the coast of Ensenada, Mexico

open access: yesCiencias Marinas, 2017
Coccoliths and foraminifera fluxes and their contributions to CaCO3 were estimated by analyzing the material collected by a sediment trap installed in the area adjacent to Ensenada, Baja California (Mexico).

Textural variations in Neogene pelagic carbonate ooze at DSDP Site 593, southern Tasman Sea, and their paleoceanographic implications [PDF]

open access: yes, 2004
Changes in Neogene sediment texture in pelagic carbonate-rich oozes on the Challenger Plateau, southern Tasman Sea, are used to infer changes in depositional paleocurrent velocities.

A deep-sea coral record of North Atlantic radiocarbon through the Younger Dryas: Evidence for intermediate water/deepwater reorganization [PDF]

open access: yes, 2006
Our record of Younger Dryas intermediate-depth seawater Δ^(14)C from North Atlantic deep-sea corals supports a link between abrupt climate change and intermediate ocean variability.

Early to middle Miocene foraminifera from the deep-sea Congo Fan, offshore Angola [PDF]

open access: yes, 2008
Analysis of a 630m section of an exploration well penetrating the distal part of the Congo Fan (~2000m water depth) yielded high abundance and diversity assemblages of agglutinated and calcareous benthic foraminifera.

Remarks on the type locality and current status of the foraminiferal species Rzehakina epigona (Rzehak, 1895) [PDF]

open access: yes, 2001
A likely topotype locality is proposed for Rzehakina epigona. As the type specimen of Silicina epigona Rzehak, 1895 is assumed to be lost, we undertook a search for new material in the type area, Zdounky village in Moravia. A single locality provided a

Preface: The planktonic foraminifera of the Jurassic

open access: yesSwiss Journal of Palaeontology, 2017
Planktonic foraminifera originated in late Early Jurassic and, for reasons poorly understood, only underwent proliferation of species and geographic spreading from mid-Cretaceous onwards. Their evolutionary development in the oceans and adjacent seaways since early mid-Cretaceous has spurned a large volume of increasingly sophisticated literature ...

DISTRIBUCION DE LOS FORAMINIFEROS PLANCTONICOS DEL PLIOCENO EN LA PLATAFORMA CONTINENTAL DEL SW DE ESPANA

open access: yesRivista Italiana di Paleontologia e Stratigrafia, 2023
Planktonic Foraminifera assemblages from cores of a borehole are studied. Depth interval is from 380 m to 2300 m. The drill site is located in the continental shelf of "Golfo de Cadiz" (SW Spain).

Quantifying the effect of seasonal and vertical habitat tracking on planktonic foraminifera proxies

open access: yes, 2016
. The composition of planktonic foraminiferal (PF) calcite is routinely used to reconstruct climate variability. However, PF ecology leaves a large imprint on the proxy signal: seasonal and vertical habitats of PF species vary spatially, causing variable

Long-Term Trends in Calcifying Plankton and pH in the North Sea [PDF]

open access: yes, 2013
Relationships between six calcifying plankton groups and pH are explored in a highly biologically productive and data-rich area of the central North Sea using time-series datasets.
