The impact of essential climate variables on respiration rates in subpolar and polar planktonic foraminifera

Diane V. Armitage, Nicolaas Glock, Thomas L. Weiss, Mohamed Mahmoud Ezat et autres

Abstract. This study investigates the impact of Essential Climate Variables (ECVs) on the respiration rate of polar planktonic foraminifera Neogloboquadrina pachyderma and subpolar Turborotalita quinqueloba and Neogloboquadrina incompta to advance our understanding of foraminifera physiology and geochemical proxy interpretation for species living …

Unifying Retaria Research: A Common Framework for Studying Foraminifera and Radiolaria

Miguel M. Sandin, Nicole L. Coots, Nicolaas Glock, Mattia Greco et autres

Spanning over 500 million years, the fossil record of Retaria is a cornerstone of paleobiology, paleoclimate reconstruction, and stratigraphy. Yet, the constitutive branches of Retaria, Foraminifera, and Radiolaria, not only have been studied independently, but just a fraction of this research has …

Expansion of the Eastern Tropical North Pacific Oxygen Minimum Zone During the Last Deglaciation Recorded by Planktic Foraminifera

Rachel Alcorn, Jorge Feliciano Ontiveros-Cuadras, Anjaly Govindankutty Menon, Nicolaas Glock et autres

Abstract Climate change is currently driving the expansion of oxygen minimum zones (OMZs), areas of the open ocean with consistently low oxygen levels. Changes in temperature, productivity and consequent respiration, and water mass ventilation drive OMZ expansion and contraction with implications for …

Age model built from planktic foraminifera radiocarbon in the eastern Pacific during the last deglaciation determined from core MAZ-1E-04 collected on cruise MAZ-I aboard the R/V El Puma in April 2015

Rachel Alcorn, Jorge Feliciano Ontiveros-Cuadras, Anjaly Govindankutty Menon, Nicolaas Glock et autres

The structure and drivers of oxygen minimum zone (OMZ) evolution in the Eastern Tropical North Pacific (ETNP) are investigated from ~20.7-10 ka using a multi-proxy approach from core MAZ-1E-04 (22°54.29’N, 106°54.59’W; 1463 m depth). Understanding how OMZ vertical structure changed during past …

Quantitative reconstruction of deglacial bottom-water nitrate in marginal Pacific seas using the pore density of denitrifying benthic foraminifera

Anjaly Govindankutty Menon, Aaron L. Bieler, Hanna Firrincieli, Rachel Alcorn et autres

Quantifying past ocean nitrate concentrations is crucial for understanding the global nitrogen cycle. Here, we reconstruct deglacial bottom-water nitrate concentrations ([NO3-] BW ) in the oxygen-deficient zones of the Sea of Okhotsk, the Gulf of California, the Mexican Margin, and the Gulf …

Quantifying past ocean nitrate concentrations is crucial for understanding the global nitrogen cycle. Here, we reconstruct deglacial bottom-water nitrate concentrations ([NO3-]BW) in the oxygen-deficient zones of the Sea of Okhotsk, the Gulf of California, the Mexican Margin, and the Gulf of Guayaquil. …

Different Elemental Compositions and Potential Functions of Vacuoles in Bolivina spissa (Foraminifera, Rhizaria) Based on Cryo‐SEM‐EDS Analyses

Julien Richirt, Satoshi Okada, Yoshiyuki Ishitani, Nicolaas Glock et autres

ABSTRACT Benthic Foraminifera exhibit diverse adaptations to low oxygen (O 2 ) environments, including denitrification, a rare trait among eukaryotes. Denitrifying species store intracellular nitrate (NO 3 − ), possibly within vacuoles, and contribute significantly to the global marine nitrogen (N) cycle. …

Change in biodiversity and abundance of benthic foraminifera with distance from the Rainbow hydrothermal vent field, Mid-Atlantic Ridge

Gerhard Schmiedl, Zvi Steiner, Zhouling Zhang, Eric P. Achterberg et autres

In the vicinity of hydrothermal vent fields, unique habitats are observed that are influenced by hydrothermal fluids. Benthic foraminifera can be part of the communities found around these hydrothermal vent fields. They can form suitable indicators for different marine environmental conditions because …
