Development of freeze-thaw processing technique for disaggregation of indurated mudrocks and enhanced recovery of calcareous microfossils [PDF]

, 2014
Microfossil extraction from indurated mudrocks is widely acknowledged as challenging, especially for foraminifera. Here we report development of the freeze–thaw extraction method through the addition of rapid heating, detergent and ultrasound stages.

Domed‐rim microbial polygons and their preservation potential

The Depositional Record, Volume 12, Issue 1, February 2026.
Microbially induced sedimentary structures (MISS) derive through interactions between minerals and microorganisms. We define a domed‐rim MISS, morphologically distinct from abiotic mud cracks and demonstrate its potential for long‐term preservation. These structures represent promising biosignatures in ancient environments on Earth and potentially Mars.

Orbital Variability in Grazing Proportion: New Insights From Sedimentary Amino Acid δ15N Records of the Western Equatorial Pacific

AGU Advances, Volume 7, Issue 1, February 2026.
Abstract The carbon sequestration capacity of the biological carbon pump (BCP) is determined by surface ocean carbon fixation and the transportation of fixed carbon to the ocean interior, which is closely linked to the trophic structure of planktonic ecosystem.

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.

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).

Miocene deep-water agglutinated foraminifera from the Lomonosov Ridge and the opening of the Fram Strait [PDF]

, 2009
Deep-water agglutinated Foraminifera (DWAF) were recovered from Miocene to Pliocene sediments in 103 samples from IODP Hole M0002A on the Lomonosov Ridge.

Sea surface temperature changes in the southern California borderlands during the last glacial-interglacial cycle [PDF]

, 1996
A variety of evidence suggests that average sea surface temperatures (SSTs) during the last glacial maximum in the California Borderlands region were significantly colder than during the Holocene.

Silicate and Carbonate Weathering Perturbation at the Eocene‐Oligocene Transition Recorded by Mg Isotopes

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 2, February 2026.
Abstract During the Eocene‐Oligocene Transition (ca. 34 Ma), the Earth underwent a dramatic decline in atmospheric CO2, global cooling, a deepening of the carbonate compensation depth (CCD), and the formation of a permanent ice sheet on Antarctica. The expansion of Antarctic glaciers eroded the underlying bedrock and increased the weathering flux to ...
