Late Quaternary climatic variability in the Eastern Mediterranean recorded in Hermes Cave, Corinth Rift, Greece

Journal of Quaternary Science, Volume 41, Issue 5, Page 821-836, July 2026.
ABSTRACT The Greek peninsula lies at the intersection of major atmospheric circulation systems, making it a key location for reconstructing past climate variability in the Eastern Mediterranean. In this study, we present a new high‐resolution multi‐proxy speleothem record from Hermes Cave, located on the shoulder of the Corinth Rift in southern Greece.

Cold-Water Coral Mound Archive Provides Unique Insights Into Intermediate Water Mass Dynamics in the Alboran Sea During the Last Deglaciation

Frontiers in Marine Science, 2020
The Alboran Sea is widely recognized to host numerous cold-water coral ecosystems, including the East Melilla Coral Province. Yet, their development through time and response to climatic variability has still to be fully understood.

The Paleoenvironment of the Ndutu Bed at Olduvai Gorge in the Context of Middle Stone Age Expansion in Eastern Africa: A Multiproxy Approach to Ungulate Analyses From the Victoria Cabrera Site and Dorothy Garrod Site (MIS 5)

International Journal of Osteoarchaeology, Volume 36, Issue 4, Page 1100-1113, July/August 2026.
ABSTRACT The study of the Eastern African archaeological record is essential for understanding the origin and evolution of the Middle Stone Age (MSA). However, Olduvai Gorge, one of the primary regions in human evolution studies, has few sites associated with the MSA.

Correlative X‐Ray and Neutron Tomography of Microbial Biosignatures: Perspectives for Mars Sample Return

Earth and Space Science, Volume 13, Issue 7, July 2026.
Abstract Mars Sample Return (MSR) is the next major frontier in Mars exploration, through which advanced laboratory instrumentation will be used to study Martian samples and answer key questions surrounding Mars' planetary evolution and astrobiology. Non‐destructive, high‐resolution imaging will be critical for preliminary MSR analyses.

Orbital cycle records in shallow unconsolidated sediments: implications for global carbon cycle and hydrate system evolution in deep-sea area sediments of the Qiongdongnan Basin

Frontiers in Marine Science
IntroductionMilankovitch theory has extensive application in sequence stratigraphy and the establishment of time scales. However, it is rarely applied to shallow strata rich in hydrates.
