Biogeochemical, sedimentological and dinoflagellate‐based reconstruction of the Holocene palaeoenvironment of the east Limfjord, Denmark

Boreas, EarlyView.
To assess how the eastern part of the Limfjord system has changed over the Holocene, relative to the wider Limfjord and western Baltic region, a sedimentary succession spanning c. 9600–150 cal. a BP was collected from Nibe Bredning, near Sebbersund, from a shallow coastal inlet along the eastern connection between the Limfjord and the Kattegat (north ...

Exploring the controls on element ratios in middle Eocene samples of the benthic foraminifera Oridorsalis umbonatus [PDF]

Culturing studies and empirically based core top calibrations have been used to infer that elemental ratios in benthic foraminifera can be used as proxies to reconstruct past variations in bottom water temperature and saturation state (Δ [CO32 ...

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.

Are Past Sea-Ice Reconstructions Based on Planktonic Foraminifera Realistic? Study of the Last 50 ka as a Test to Validate Reconstructed Paleohydrography Derived from Transfer Functions Applied to Their Fossil Assemblages

Geosciences, 2021
Since its existence, paleoceanography has relied on fossilized populations of planktonic foraminifera. Except for some extreme environments, this calcareous protist group composes most of the silty-to-sandy fraction of the marine sediments, i.e., the ...

Contourite erosional and depositional features of the Maastrichtian chalk on Jasmund peninsula (Rügen island, NE Germany)

Sedimentology, EarlyView.
ABSTRACT Seismic‐scale features such as deeply incised submarine valleys and mounded drifts together with ichnological features indicative of discontinuous sedimentation and erosional episodes have recently been documented from the Upper Cretaceous chalk in the southern Baltic Sea area.

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/

Riding the Storm: Microeukaryote Community Responses to Hurricane Disturbance. [PDF]

J Eukaryot Microbiol
ABSTRACT Sandy beaches are dynamic ecosystems where terrestrial and marine organisms coexist, resulting in diverse communities where microeukaryotes (protists, microalgae, and meiofauna) are key drivers. Understanding their diversity patterns and responses to stressors is essential for elucidating ecological processes, yet information on this subject ...

Drowned carbonate‐rimmed margin controlling shelf‐edge delta progradation and sedimentation dynamics: Upper Cretaceous Woodbine Formation, Texas, USA

Sedimentology, EarlyView.
ABSTRACT Shelf‐edge deltas are commonly interpreted to record basinward facies migration across uninterrupted, gently dipping shelf margins; however, examples from mixed siliciclastic‐carbonate margins reveal more complex depositional dynamics. Periods and areas of carbonate sedimentation within mixed siliciclastic‐carbonate margins can modify shelf ...

Physiological controls on seawater uptake and calcification in the benthic foraminifer Ammonia tepida [PDF]

, 2009
To analyze the relation between seawater uptake and calcification, we incubated juveniles of the benthic foraminifer Ammonia tepida with various fluorescent probes and visualised them afterwards with confocal laser scanning microscopy. Vesicle membranes,

The new and reinstated genera of agglutinated foraminifera published between 1986 and 1996 [PDF]

, 2001
In the 10 years following the publication of "Foraminiferal Genera and their Classification" by Loeblich & Tappan (1987), some 91 new genera of agglutinated foraminifera have been proposed by various authors.
