Intermediate Western Boundary Current speeds from the southeastern Brazilian margin: A 16,000‐year record from grain‐size evidence

Limnology and Oceanography Letters, Volume 11, Issue 2, March 2026.
Abstract This study presents a high‐resolution reconstruction of the Antarctic Intermediate Water (AAIW) transport variability on the southeastern Brazilian continental margin over the last 16,000 years BP, based on grain‐size analysis. Variations of sortable silt (SS¯$$ \overline{SS} $$) are interpreted as changes in flow speed of the Intermediate ...

Benthic foraminifers and siliceous sponge spicules assemblages in the Quaternary rhodolith rich sediments from Pontine Archipelago shelf [PDF]

, 2016
The bottom samples (Quaternary in age) of two cores (CS1 and Caro1) collected at 60 and 122 m water depth in the marine area near Ponza Island (Pontine Archipelago, Tyrrhenian Sea) are investigated.

A Revised Estimate of Calcium Carbonate Dissolution in Coastal and Shelf Sediments Suggests Large Shelf Exports in the Marine CaCO3 Cycle

Global Biogeochemical Cycles, Volume 40, Issue 3, March 2026.
Abstract Calcium carbonate (CaCO3) dissolution plays a key role in the marine carbon and alkalinity cycles and the regulation of atmospheric CO2 levels across geological time scales. Until now, most attention has focused on dissolution in the deep sea, while dissolution in coastal and shelf environments remains poorly constrained.

Mortality, protoplasm decay rate, and reliability of staining techniques to recognise 'living' foraminifera: a review.

, 2000
Non-vital staining, especially with rose Bengal, has been widely used in ecological studies to differentiate between the tests of dead(unstained) foraminifera from those presumed to be living at the time of collection (stained).

Diagenetic Effect on Planktic Foraminiferal Mg/Ca Records in the Arctic Ocean

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 3, March 2026.
Abstract Mg/Ca ratios in planktic foraminifera have long been used as a thermometer to reconstruct the past climate. However, this study revealed that in certain intervals, the Mg/Ca ratios of the planktic foraminifer Neogloboquadrina pachyderma, a widespread species in the Arctic Ocean, displayed anomalously high values which could severely bias paleo‐

Kondisi Foraminifera Bentik Sebagai Bioindikator Pada Ekosistem Terumbu Karang Di Kawasan Konservasi Perairan Pesisir Timur Pulau Weh, Sabang, Aceh, Indonesia

Jurnal Kelautan Tropis
The East Coast Marine Conservation Area of Pulau Weh, Sabang (KKP PTPW) holds a lot of potential natural wealth. One of them is foraminifera which lives in coral reef sediments.

Changes in Shell and Crystal Structure From Life to Sediments: An EBSD Characterization of Subantarctic Planktic Foraminifera

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 3, March 2026.
Abstract Fossil foraminifera store a wealth of information about past climates and ecosystems in their shell chemistry. However, these element and isotope signals may be affected by post‐mortem diagenesis (i.e., alteration). Here, we use Electron Backscatter Diffraction (EBSD; crystal orientation mapping) to evaluate the structural integrity of sub ...
