Testing the extraction of past seawater Nd isotopic composition from North Atlantic deep sea sediments and foraminifera

Geochemistry, Geophysics, Geosystems, 2011
Neodymium isotopes provide a paleoceanographic proxy for past deep water circulation and local weathering changes and have been measured on various authigenic marine sediment components, including fish teeth, ferromanganese oxides extracted by acid ...

Temporal variation of particle flux in the Seychelles–Chagos Thermocline Ridge region of the western Indian Ocean (2022–2024): Links to the Indian Ocean Dipole and El Niño–Southern Oscillation

Limnology and Oceanography Letters, Volume 11, Issue 2, March 2026.
Abstract The Seychelles–Chagos Thermocline Ridge is an upwelling region in the western Indian Ocean, but its role in sinking particle flux remains unclear. We present sediment trap records (July 2022 to June 2024) at 1000 and 2500 m to reveal variations in particle flux and composition.

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.

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 ...

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

Ciencias 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).

Note on the stratigraphic position of the Zonderschot sands member of the Berchem formation (Miocene, Belgium) [PDF]

, 1980
Planktonic foraminifera are recorded from three samples of the Zonderschot Sands Member of the Berchem Formation in the type locality at Zonderschot. Altogether 15 taxa are described.

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

Rivista 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).
