Latitudinal Heterogeneity in South Asian Monsoon Changes Since the Last Glacial Maximum Revealed by Ganga–Brahmaputra Vegetation Record

open access: yesPaleoceanography and Paleoclimatology, Volume 41, Issue 11, November 2026.
Abstract Future changes in South Asian climate are expected to amplify flooding and drought, yet the spatial and temporal variability of the South Asian monsoon (SAM) under different climate regimes remains poorly constrained. Here, we present a new marine pollen record from the Bay of Bengal (BoB), informing on the vegetation of the Ganges‐Brahmaputra

Ordovician to Lower Silurian palynomorphs from the Sierras subandinas (Subandean ranges), northwestern Argentina: a preliminary report

open access: yesCarnets de Géologie, 2005
Ordovician clastic sediments of the Central Andean Basin, northwestern Argentina, were deposited in a proto-Andean foreland basin on the western margin of Gondwana (Astini, 2003; Astini & Marengo, 2003).

Evidence for Submarine Landslides at Climate Transitions in a High Arctic Fjord (Grise Fiord, Nunavut)

open access: yesEarth Surface Processes and Landforms, Volume 51, Issue 10, October 2026.
Seafloor mapping in a high Arctic fjord (Grise Fiord) revealed many submarine landslides triggered by iceberg groundings, coastal debris flows and delta collapses. The dating of three of them suggests that they occurred at past climate transitions. ABSTRACT Arctic fjords are experiencing rapid environmental change driven by amplified high‐latitude ...

Late Holocene environmental history of Dojran, Macedonia: Investigating the interplay of imperial dynamics and climatic change

open access: yesJournal of Quaternary Science, Volume 41, Issue 7, Page 996-1019, October 2026.
ABSTRACT This study presents a high‐resolution, multi‐proxy reconstruction of environmental and land‐use change from Lake Dojran over historical times (last 2500 years), combining pollen, biomarkers, radiocarbon dating, Ottoman taxation records and other historical data.

Preserved Palynomorphs in Ephemeral Hypersaline Lakes

open access: yes, 2012
Surface sediments were sampled from Prado Lake (7 samples) and Salty Lake (5 samples) in southern Western Australia for palynological analyses. Light microscopy was utilized in examining the samples for dispersed organic matter (palynofacies) and organic-

Changing climates and environments within the complex Middle to Late Pleistocene fill of an overdeepened valley at Niederweningen, Switzerland

open access: yesBoreas, Volume 55, Issue 4, Page 964-992, October 2026.
Glacially overdeepened valleys in the northern Alpine Foreland preserve Middle to Late Pleistocene sedimentary sequences that may serve as valuable archives for reconstructing past environmental changes in response to shifts in climate. This study presents a multidisciplinary analysis of two sediment cores from the overdeepened Wehntal Valley at ...
