Holocene sea‐level and environmental changes on the Isle of Mull, Scotland
Journal of Quaternary Science, Volume 41, Issue 3, Page 400-418, April 2026.ABSTRACT Sea‐level and coastal changes are reconstructed on the Isle of Mull, western Scotland, from 10 988 to 10 507 cal BP to the present. This research has produced the first SLIP for the Isle of Mull. A multiproxy approach including pollen, spore, foraminifera and diatom analyses reveals palaeoenvironmental changes from two coastal sites.

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 4, April 2026.Abstract Stable water isotopes serve as tracers of climate processes and are useful for identifying drivers of regional and global hydrological variability. To get a precise picture of spatiotemporal changes in the water cycle, it is necessary to describe the mechanisms in a coherent way among the involved climatic reservoirs (atmosphere, land, and ...

Photometric properties of microfossil shells [PDF]
, 2009 The chromatic characteristics of fossil planktonic foraminifera were measured with the use of an opticoelectric microscope and a new aspect of their nature has been ...

Paleoceanography and Paleoclimatology, Volume 41, Issue 4, April 2026.Abstract Coccolith assemblages from the last 158 kyr, encompassing Marine Isotope Stage (MIS) 5e (130–116 kyr) and preceding deglaciation (Termination II; T‐II), offer important insights about current and future climate changes. The South China Sea (SCS) represents a perfect area for reconstructing past East Asian Monsoon (EAM) dynamics thanks to its ...

Selknamella: a new agglutinated foraminiferal genus from the early Eocene southern high latitudes [PDF]
, 2014 A new, unusual agglutinated foraminifera, Selknamella basketi n. gen., n. sp. is described from the Fuegian lower Eocene, Magallanes Basin, southernmost South America.

Changing atmospheric Δ^(14)C and the record of deep water paleoventilation ages [PDF]
, 1997 We propose a new calculation method to better estimate the deep water ventilation age from benthic-planktonic foraminifera ^(14)C ages. Our study is motivated by the fact that changes in atmospheric Δ^(14)C through time can cause contemporary benthic and

, 2017 There are several hypotheses on the origin and evolution of the earliest Danian planktonic foraminifera. Most experts suggest that they descended from a few opportunist planktonic foraminifera species, mainly of the genera Guembelitria and Hedbergella ...

Late Holocene hydrographic settings of the northern Red Sea
Egyptian Journal of Aquatic Research, 2016 Temporal variability of the paleo-oceanographic setting of the northern Red Sea during the last 6 Ky was deduced from high-resolution faunal results and stable isotope records of planktonic foraminifera in three short cores sediment obtained by the ...

Paleoceanography and Paleoclimatology, Volume 41, Issue 4, April 2026.Abstract Carbon fluxes to Earth's atmosphere are reflected in the carbon isotope composition of atmospheric CO2 (δ13Catm). δ13Catm is used to track past changes to the global carbon cycle and is a variable in many paleoclimate proxies. However, existing δ13Catm proxy records derived from marine carbonates are relatively low‐resolution prior to the ...
