Sedimentary and Diagenetic Controls across the Cretaceous—Paleogene Transition: New Paleoenvironmental Insights of the External Ionian Zone from the Pelagic Carbonates of the Gardiki Section (Epirus, Western Greece)

Journal of Marine Science and Engineering, 2022
Field investigation, biostratigraphic, paleoecological, and sedimentary microfacies analyses, as well as diagenetic processes characterization, were carried out in the Epirus region (Western Ionian Basin) to define the depositional environments and ...

Sedimentation environment of the Cojimar Formation (Havana province) based on benthic foraminifera

Minería y Geología, 2022
Cojímar Formation, —Lower Miocene (upper part) to Middle Miocene (lower part)—, is a unit in Western Cuba well known for its extensive development and exposure outcrops. It has been widely used in bioestratigraphic studies.

Planktonic foraminifera assemblage composition and flux dynamics inferred from an annual sediment trap record in the central Mediterranean Sea [PDF]

Biogeosciences
The Sicily Channel, located in the central Mediterranean Sea, represents a key point for the regional oceanographic circulation, as it is regarded as the sill that separates the western and eastern basins.

Upper ocean mixing controls the seasonality of planktonic foraminifer fluxes and associated strength of the carbonate pump in the oligotrophic North Atlantic [PDF]

Biogeosciences, 2015
Oligotrophic regions represent up to 75% of Earth's open-ocean environments. They are thus areas of major importance in understanding the plankton community dynamics and biogeochemical fluxes.

Triassic and Jurassic possible planktonic foraminifera and the assemblages recovered from the Ogrodzieniec Glauconitic Marls Formation (uppermost Callovian and lowermost Oxfordian, Jurassic) of the Polish Basin [PDF]

Journal of Micropalaeontology, 2023
In the 1960s and 1970s Werner Fuchs of the Austrian Geological Survey (Vienna) described a significant number of new foraminiferal taxa that he considered ancestral to the planktonic foraminifera. All these taxa are well-curated in the collections of the

Early Aptian marine incursions in the interior of northeastern Brazil following the Gondwana breakup

Scientific Reports, 2023
This study reports a set of primeval marine incursions identified in two drill cores, 1PS-06-CE, and 1PS-10-CE, which recovered the Barbalha Formation, Araripe Basin, Brazil.

Planktonic foraminiferal assemblages reflect warming during two recent mid-latitude marine heatwaves

Frontiers in Marine Science, 2023
Under future climate scenarios, ocean temperatures that are presently extreme and qualify as marine heatwaves (MHW) are forecasted to increase in frequency and intensity, but little is known about the impact of these events on one of the most common ...

The contributions of various calcifying plankton to the South Atlantic calcium carbonate stock [PDF]

Biogeosciences
Pelagic calcifying plankton play an important role in the marine carbon cycle. However, field studies quantifying the contributions of multiple calcifying plankton groups to particulate inorganic carbon (PIC) stocks and export into the ocean interior are

A quantitative look on northwestern Tethyan foraminiferal assemblages, Campanian Nierental Formation, Austria [PDF]

PeerJ, 2016
Deposits spanning the Radotruncana calcarata Taxon Range Zone at the Postalm section, Northern Calcareous Alps (Austria) are examined quantitatively for foraminiferal assemblages, especially the planktonic group. This study focuses on establishing a high
