The mineral and isotopic signatures of glacially eroded sediments exported from Hudson Strait to the Labrador Sea during Hudson Strait Heinrich events H0 to H4

Journal of Quaternary Science, Volume 41, Issue 1, Page 4-24, January 2026.
ABSTRACT The sediment signature of glacial erosion products exported from Hudson Strait to the Labrador Sea during Hudson Strait Heinrich (HS‐H) events is evaluated using four distinct proxies: paired δ18Ο and δ13C data on the carbonate fraction, εNd and U–Pb isotopes in the silicate fraction, the mineral composition of the <2 mm bulk sediment fraction,

New age‐estimate data and implications for marine isotope stage 7 and 5e sea levels in Fenland, eastern England

Journal of Quaternary Science, Volume 41, Issue 1, Page 36-60, January 2026.
ABSTRACT Only one last interglacial relative sea‐level indicator point (SLIP) has been recognised for Fenland, eastern England, and the nearest penultimate interglacial SLIP is located on the north Norfolk coast. Such limited information restricts the regional input to, and hence the relevance of, global reconstructions of late Middle and Late ...

Nd Isotope Response to Precipitation Variability in the Western Tropical Pacific Over the Last 30 kyr

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 1, January 2026.
Abstract Dissolved neodymium (Nd) isotopes are key tracers for water mass mixing in the open ocean and for land‐ocean exchanges in marginal seas. Hydrogenous Nd isotope ratios (expressed as εNd) in cores north of the equator reflect values of the surrounding lithology and tend to vary in accordance with local rainfall records, indicating higher ...

Shifts in Fossil Benthic Foraminiferal Community Trajectories During the Last Deglaciation Along the European Margin

Paleoceanography and Paleoclimatology, Volume 41, Issue 1, January 2026.
Abstract Constraining how faunal communities vary over time and space in response to environmental change has long been a major goal of paleoecologists. Among fossilized organisms, few yield a better and greater detailed record than foraminifera to understand past marine conditions.

The Romantic Discovery of Radiolaria in the Ocean

Journal of Eukaryotic Microbiology, Volume 73, Issue 1, January/February 2026.
ABSTRACT Radiolaria are unicellular marine organisms (protists) that have been drifting in oceanic plankton for hundreds of millions of years. These mineral architects can build extraordinarily complex skeletons, which fascinated and puzzled naturalists observing water samples through rudimentary microscopes.

Late Holocene hydrographic settings of the northern Red Sea

Egyptian Journal of Aquatic Research, 2016
Temporal variability of the paleo-oceanographic setting of the northern Red Sea during the last 6 Ky was deduced from high-resolution faunal results and stable isotope records of planktonic foraminifera in three short cores sediment obtained by the ...
