Water‐Depth‐Dependent 231Pa/230Th Responses in the Central North Atlantic Since the Last Glacial Maximum

open access: yesPaleoceanography and Paleoclimatology, Volume 41, Issue 6, June 2026.
Abstract The Atlantic Meridional Overturning Circulation (AMOC) plays an important role in regulating Earth's climate through inter‐hemispheric heat transport and has undergone substantial variations during past climate transitions. Sedimentary 231Pa/230Th is widely used to reconstruct AMOC strength, yet its application is complicated by its ...

“Flames Over Persepolis”: New Scientific Evidence Supporting Historical Perspectives

open access: yesArchaeometry, Volume 68, Issue 3, Page 421-433, June 2026.
ABSTRACT This study investigates the burning of Persepolis Terrace, historically attributed to Alexander III in 330 bce. A review of classical accounts and excavation reports, combined with diagnostic surveys, confirms the fire's historicity and provides novel insights.

Late Holocene hydrographic settings of the northern Red Sea

open access: yesEgyptian 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 ...

In Search of the Lost Brown Trout (Salmo trutta Complex) Using DNA of Ancient and Modern Samples From the Southern Italian Peninsula

open access: yesEvolutionary Applications, Volume 19, Issue 6, June 2026.
ABSTRACT The current diversity and distribution of species and populations have been shaped by the major climatic oscillations during the Quaternary. The brown trout (Salmo trutta) is a striking example of the strong effect of past climate changes on the evolutionary history of species, in fact, the alternation of glacial/interglacial cycles has led to

Testing the extraction of past seawater Nd isotopic composition from North Atlantic deep sea sediments and foraminifera

open access: yesGeochemistry, Geophysics, Geosystems, 2011
Neodymium isotopes provide a paleoceanographic proxy for past deep water circulation and local weathering changes and have been measured on various authigenic marine sediment components, including fish teeth, ferromanganese oxides extracted by acid ...

Preface: The planktonic foraminifera of the Jurassic

open access: yesSwiss Journal of Palaeontology, 2017
Planktonic foraminifera originated in late Early Jurassic and, for reasons poorly understood, only underwent proliferation of species and geographic spreading from mid-Cretaceous onwards. Their evolutionary development in the oceans and adjacent seaways since early mid-Cretaceous has spurned a large volume of increasingly sophisticated literature ...

Into the Wild: Farm‐Derived Energy and Nutrients Enter Marine Food Webs With Carrying Capacity Implications for Aquaculture Management

open access: yesReviews in Aquaculture, Volume 18, Issue 3, June 2026.
ABSTRACT Marine aquaculture is expanding globally, yet its interactions with surrounding ecosystems remain complex and insufficiently understood. This study reviews the fluxes of energy and nutrients from three major aquaculture systems: finfish cages, suspended bivalves, and seaweed farms and considers their implications for ecosystem functioning and ...
