Ostracod and Foraminifer Responses to Late Pleistocene–Holocene Volcanic Activity in Northern Victoria Land as Recorded in Ross Sea (Antarctica) Marine Sediments

open access: yesGeosciences, 2023
The impacts on ostracods and foraminifers caused by three Late Quaternary ashfalls of different intensities and recovered in the ANTA02-NW2 core sediments (Drygalski Basin, western Ross Sea) were analysed for the first time. Albeit with different timing,

A robust calibration of the clumped isotopes to temperature relationship for foraminifers

open access: yes, 2020
The clumped isotope (Δ47) proxy is a promising geochemical tool to reconstruct past ocean temperatures far back in time and in unknown settings, due to its unique thermodynamic basis that renders it independent from other environmental factors like ...

Foraminifer or Sponge? [PDF]

open access: yesNature, 1893
I AM glad to find that Mr. Pearcey agrees with me in regarding Neusina Agassizi, Goes, as identical with Stannophyllum zonarium, Haeckel. But with respect to its systematic position I do not as yet see sufficient reason to differ from Prof. Haeckel in regarding it as a sponge, although I have never observed flagellated chambers and cells any more than ...

Upper Cretaceous, K/T boundary, and Paleocene agglutinated foraminifers from Hole 959D (Côte d'Ivoire-Ghana Transform Margin) [PDF]

open access: yes, 1998
Upper Cretaceous agglutinated foraminifer assemblages from Hole 959D of Ocean Drilling Program (ODP) Leg 159, Côte d’Ivoire-Ghana Transform Margin, reflect the subsidence history and paleoceanography of the widening equatorial Atlantic gateway.

Biostratigraphy of Eocene to Oligocene deep-water agglutinated foraminifers in the red clays from Site 767, Celebes Sea [PDF]

open access: yes, 1991
Deep-water agglutinated foraminifers were examined from reddish brown claystones comprising lithologic Unit 4 of Ocean Drilling Program Holes 767B and 767C. The biostratigraphy of deep-water agglutinated foraminifers in this unit indicates an Eocene to

Past Analogues of Deoxygenation Events in the Mediterranean Sea: A Tool to Constrain Future Impacts

open access: yesJournal of Marine Science and Engineering, 2023
Human-induced carbon emissions are altering the modern climate, with severe repercussions on ecosystems. Among others, anthropogenic pressure is causing deoxygenation of the bottom water, with the widespread establishment of hypoxic zones in several ...

Response of Pelagic Calcifiers (Foraminifera, Thecosomata) to Ocean Acidification During Oligotrophic and Simulated Up-Welling Conditions in the Subtropical North Atlantic Off Gran Canaria

open access: yesFrontiers in Marine Science, 2018
Planktonic Foraminifera and thecosome pteropods are major producers of calcite and aragonite in the ocean and play an important role for pelagic carbonate flux.
