It Takes a '‘Superhero’' to Uncover the Climate Secrets in Fossilized Arctic Ocean Dinocysts

open access: yesCurrent: The Journal of Marine Education, 2020
The Snow On Ice project developed curricular materials using scientists depicted as superheroes as a means of engaging students and providing a novel method to link current climate change in the Arctic to Middle-Holocene Warming—a topic that might seem ...

Paleontological Evidence for Dinoflagellates and Ciliates as Early Eukaryotes

open access: yesJournal of Marine Science and Engineering, 2023
Molecular trees and geochemical markers suggest the divergence of dinoflagellates as early eukaryotes (~650 million years ago), but the traditional fossil record of cysts (dinocysts) starts during the Triassic (~230 million years ago). A re-evaluation of

The correlation of the Neogene of Central and Eastern Paratethys segments of Ukraine with the International Stratigraphic Chart based on planktonic microfossils

open access: yesGeologica Carpathica, 2015
Detailed analysis of microplankton occurrence (planktonic foraminifera, nannoplankton, dinocysts) in Neogene sediments situated at the north-western and south-eastern margins of Ukraine enabled us to distinguish 10 associations of oceanic plankton which ...

Single-species dinoflagellate cyst carbon isotope fractionation in core-top sediments: environmental controls, CO2 dependency and proxy potential [PDF]

open access: yesBiogeosciences, 2023
Sedimentary bulk organic matter and various molecular organic components exhibit strong CO2-dependent carbon isotope fractionation relative to dissolved inorganic carbon sources. This fractionation (εp) has been employed as a proxy for paleo-pCO2.

Biostratigraphic correlation of the western and eastern margins of the Labrador–Baffin Seaway and implications for the regional geology. Fig. 5 [PDF]

open access: yesGeological Survey of Denmark and Greenland Bulletin, 2016
New analyses of the palynological assemblages in 13 offshore wells on the Canadian margin and six on the West Greenland Margin, in conjunction with onshore data, have led to a new biostratigraphic framework for the Cretaceous–Cenozoic strata of the ...

Lower miocene stratigraphy of the Eastern Paratethys: Problems and state of the art [PDF]

open access: yesGeološki Anali Balkanskoga Poluostrva
The Lower Miocene regional stages of the Eastern Paratethys, the Caucasian, Sakaraulian, and Kozakhurian, have been recognized in different structural facies zones of the basin and have no reliable universal stratigraphic basis for defining their ...
