The Foraminiferal Response to Climate Stressors Project: Tracking the Community Response of Planktonic Foraminifera to Historical Climate Change

Frontiers in Marine Science, 2022
Planktonic Foraminifera are ubiquitous marine protozoa inhabiting the upper ocean. During life, they secrete calcareous shells, which accumulate in marine sediments, providing a geological record of past spatial and temporal changes in their community ...

Calcification intensity in planktonic Foraminifera reflects ambient conditions irrespective of environmental stress [PDF]

Biogeosciences, 2013
Planktonic Foraminifera are important marine calcifiers, and the ongoing change in the oceanic carbon system makes it essential to understand the influence of environmental factors on the biomineralization of their shells.

Biostratigraphic and Geological Significance of Planktonic Foraminifera, Updated Second Edition [PDF]

, 2015
The role of fossil planktonic foraminifera as markers for biostratigraphical zonation and correlation underpins most drilling of marine sedimentary sequences and is key to hydrocarbon exploration.

Review and revision of Cenozoic tropical planktonic foraminiferal biostratigraphy and calibration to the Geomagnetic Polarity and Astronomical Time Scale [PDF]

, 2010
Planktonic foraminifera are widely utilized for the biostratigraphy of Cretaceous and Cenozoic marine sediments and are a fundamental component of Cenozoic chronostratigraphy.

Planktonic foraminiferal turnover across the Cenomanian – Turonian boundary (OAE2) in the northeast of the Tethys realm, Kopet-Dagh Basin

Geologica Carpathica, 2016
Two Late Cenomanian – Early Turonian (C–T) intervals of the eastern part of the Kopet-Dagh basin, NE Iran have been investigated to evaluate the response of planktonic foraminifera to the geological event OAE2. The Gharesu and Taherabad sections with the

Oxygen isotope ecology of recent planktic foraminifera at the central Walvis Ridge (SE Atlantic) [PDF]

, 2005
Above the Walvis Ridge, in the SE Atlantic Ocean, we collected living plantkic foraminifera from the upper water column using depth stratified plantkon tows. The oxygen isotope composition (

First report of modern planktonic foraminifera in the southeastern Arabian Gulf, with observations on the morphology and ecology of Neogallitellia vivans (Cushman) [PDF]

Journal of Micropalaeontology
This study reports the first documented occurrence of planktonic foraminiferal assemblages from core and grab samples collected from the United Arab Emirates (UAE) sector of the Arabian Gulf, specifically from offshore Abu Dhabi.

Planktonic foraminifera-derived environmental DNA extracted from abyssal sediments preserves patterns of plankton macroecology [PDF]

Biogeosciences, 2017
Deep-sea sediments constitute a unique archive of ocean change, fueled by a permanent rain of mineral and organic remains from the surface ocean. Until now, paleo-ecological analyses of this archive have been mostly based on information from taxa ...

Environmental Controls of Size Distribution of Modern Planktonic Foraminifera in the Tropical Indian Ocean

Geochemistry, Geophysics, Geosystems, 2023
Paleoceanographic studies often rely on abundance changes in microfossil species, with little consideration for characteristics such as organism size, which may also be related to environmental changes.

Morphologic, biogeographic and ontogenetic investigation of Mid-Pliocene menardellids (planktonic foraminifera) [PDF]

, 2013
The definition of planktonic foraminifera species remains a major challenge, despite their central place in biostratigraphy and paleoceanography. During the last decade, combined outcomes of molecular and morphometric studies have brought to the light ...
