Amplified North Atlantic Little Ice Age Cooling Inferred From Inversion of Benthic Foraminiferal Records

Paleoceanography and Paleoclimatology, Volume 41, Issue 4, April 2026.
Abstract Paleoceanographic reconstructions indicate a large‐scale cooling in the last millennium, but significant disagreement on the spatial pattern and timing still exists. This disagreement is partially due to the inference of surface conditions from sparse, noisy, near‐surface marine fauna that exhibit seasonal and habitat depth biases.

Miocene deep water agglutinated foraminifera from Viosca Knoll, offshore Louisiana (Gulf of Mexico) [PDF]

, 2004
An exploration well from the Gulf of Mexico, Amoco Viosca Knoll-915, has been studied in order to document the Neogene foraminiferal assemblages. Ditch cuttings samples from the Amoco V.K.

Change in the North Atlantic circulation associated with the mid-Pleistocene transition [PDF]

, 2018
The southwestern Iberian margin is highly sensitive to changes in the distribution of North Atlantic currents and to the position of oceanic fronts. In this work, the evolution of oceanographic parameters from 812 to 530 ka (MIS20-MIS14) is studied based

Factors controlling the depth habitat of planktonic foraminifera in the subtropical eastern North Atlantic

, 2016
. Planktonic foraminifera preserved in marine sediments archive the physical and chemical conditions under which they built their shells. To interpret the paleoceanographic information contained in fossil foraminifera, the recorded proxy signals have to ...

Methodology for Single-Cell Genetic Analysis of Planktonic Foraminifera for Studies of Protist Diversity and Evolution

Frontiers in Marine Science, 2016
Single-cell genetic analysis is an essential method to investigate the biodiversity and evolutionary ecology of marine protists. In protist groups that do not reproduce under laboratory conditions, this approach provides the only means to directly ...

Age of the earliest transgressive event in the Krishna-Godavari Basin, India: evidence from dinoflagellate cysts and planktonic foraminifera biostratigraphy

Journal of Palaeogeography, 2020
A combined biostratigraphic study of dinoflagellate cysts and foraminifera was carried out on Early Cretaceous subsurface well cutting sediments from well A (DNG) (2800–2746 m depth) from the Krishna-Godavari Basin, India.

Cyanobacterial endobionts within a major marine planktonic calcifier ( Globigerina bulloides , Foraminifera) revealed by 16S rRNA metabarcoding

, 2017
. We investigated the possibility of bacterial symbiosis in Globigerina bulloides, a palaeoceanographically important, planktonic foraminifer. This marine protist is commonly used in micropalaeontological investigations of climatically sensitive subpolar

Marine ecology conditions at Weda Bay, North Maluku based on statistical analysis on distribution of recent foraminifera

MATEC Web of Conferences, 2017
Analysis of foraminifera in geology,usually being used to find the age of rocks/ sediments and depositional environment. In this study, recent foraminifera was used not only to determinethe sedimentary environment,but also to estimate the ecological ...

Cenozoic paleoceanography 1986: An introduction [PDF]

, 1987
New developments in Cenozoic paleoceanography include the application of climate models and atmospheric general circulation models to questions of climate reconstruction, the refinement of conceptual models for interpretation of the carbon isotope record

Salinity controls on Na incorporation in Red Sea planktonic foraminifera

, 2016
Whereas several well-established proxies are available for reconstructing past temperatures, salinity remains challenging to assess. Reconstructions based on the combination of (in)organic temperature proxies and foraminiferal stable oxygen isotopes ...
