Can the pattern of foraminiferal intratest trace element variations be explained by Ca dilution during biomineralization? [PDF]

open access: yes, 2010
Recently Hathorne et al. (2009) documented large intratest trace element (TE) variations in planktonic foraminifera from a single sediment trap sample that could not be explained by variations in water column properties.

Mo Isotopic Records Imply Persistent Ocean Oxygenation in the Deep Southwest Pacific During the Early Cenozoic Warming Period

open access: yesGeophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract During the early Cenozoic greenhouse period, counterintuitive contractions in tropical Pacific oxygen‐deficient zones have been linked to enhanced deep‐ocean ventilation, yet direct geological evidence remains limited. Here we present molybdenum (Mo) isotopic records from International Ocean Discovery Program Site U1509.

Sediment disturbance caused by a suspension-feeding tubular agglutinated foraminifer [PDF]

open access: yes, 2004
We report the occurrence of in-situ sediment disturbance caused by a specimen of Rhabdammina observed in life position on the 1991 Mt. Pinatubo ash layer in the abyssal South China Sea.

Isothermal Thermoluminescence Dating of Coral Reef Calcite: Implications for Sea‐Level Change

open access: yesGeophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract Reconstructing past sea‐level changes is critical in Quaternary science. On remote oceanic reefs, aragonite‐to‐calcite alteration occurs during subaerial exposure, directly recording the timing of sea‐level fall. U–Th dating of coral calcite is challenging due to open‐system issues.
