Ecology of foraminifera during the middle Eocene climatic optimum in Kutch, India
Geodinamica Acta, 2017 The shallow marine carbonates of Kutch temporally correspond to the globally recognised warming period called Middle Eocene Climatic Optimum (MECO) that extended from later part of planktic foraminiferal zone E11 to E12 and Shallow Benthic Zone (SBZ) 17.

Earth's Future, Volume 14, Issue 9, September 2026.Abstract Limiting global warming to 1.5°C will require carbon dioxide removal, and Ocean Alkalinity Enhancement (OAE) is increasingly being explored as a marine carbon dioxide removal pathway. However, benthic biological responses remain much less constrained than water‐column processes and planktonic responses, even though calcareous benthic ...

Tubular agglutinated foraminifera as indicators of organic carbon flux [PDF]
, 1995 The dimensions of tubular agglutinated foraminifera such as Rhizammina and Rhabdammina respond in a predictable manner to changes in the flux of organic carbon to the sea floor. In both the modern western North Atlantic and in an ancient example (the K/

Evaluating the utility of B/Ca ratios in planktic foraminifera as a proxy for the carbonate system : a case study of Globigerinoides ruber [PDF]
, 2015 This research was funded by NERC, Grant Number: NE/D00876X/2.B/Ca ratios in foraminifera have attracted considerable scientific attention as a proxy for past ocean carbonate system.

Benthic protozoan community attributes in relation to environmental gradients in the Arabian Sea [PDF]
, 2005 “Live” (stained) and dead macrofaunal (>300 ?m fraction) foraminifera in multicorer samples (0-1 cm and 0-5 cm layers) were analysed at six stations along a transect (100-3400 m water depth) across the Oman margin (Arabian Sea) oxygen minimum zone ...

Global Biogeochemical Cycles, Volume 40, Issue 9, September 2026.Abstract The South Pacific Ocean (SPO) hosts diverse biogeographical environments including the productive Peru‐Chile upwelling region and ultra‐oligotrophic subtropical gyre; however, vast areas are understudied regarding the cycling of dissolved calcium (Ca) and strontium (Sr), and distribution of major biomineral‐forming pelagic marine organisms ...

, 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).

Biostratigraphy, facies and sequence stratigraphy of the Sarvak Formation in the Ahwaz Oil Field, North Dezful Embayment Zone [PDF]
Journal of Stratigraphy and Sedimentology Researches, 2016 Paleontological studies lead to recognition of 21 genera and 16 species of benthic foraminifera, 5 genera and 6 species of planktonic foraminifera and 3 genera and 3 species of oligosteginids.

Insights Into Microscale Biomineralization in Deep‐Sea Callogorgia Coral via Halogen Banding
Geochemistry, Geophysics, Geosystems, Volume 27, Issue 9, September 2026.Abstract Halogen incorporation into coral carbonate skeletons serves as a valuable proxy for reconstructing paleoenvironments. However, the underlying mechanisms remain poorly understood. This study employed femtosecond laser ablation‐inductively coupled plasma time‐of‐flight mass spectrometry (fs‐LA‐ICP‐TOFMS) to perform multi‐elemental (I, Br, P, Ca,

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 9, September 2026.Abstract We investigate late Holocene changes in the northern Benguela Upwelling System using a multi‐proxy approach on shallow shelf deposits from the Namibian mud belt. Three sediment cores characterized by organic carbon‐rich, anoxic, and partly gas‐bearing sediments were retrieved along a sampling transect at 23°S in August 2019.
