Multi‐Centennial Variability of the Afro‐Asian Monsoon Linked to Atlantic Meridional Overturning Circulation

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract Drivers of multi‐centennial global monsoon variability remain debated, with internal variability poorly understood. Using nine CMIP6 pre‐industrial millennial simulations, we find that the Atlantic meridional overturning circulation (AMOC) correlates with multi‐centennial fluctuations in the Afro‐Asian summer monsoon (AfroASM), which includes ...

Influence of Lateral Input of Sediments on Longitudinal Luminescence Signal in a River (Rakaia River, Aotearoa New Zealand)

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract Rivers transport sediments from mountains to oceans, shaping landscapes and transmitting environmental signals. This transfer is repeatedly interrupted by storage and remobilization, complicating efforts to reconstruct erosion histories. Luminescence‐based methods, which exploit the progressive zeroing of the luminescence signals (bleaching ...

Rapid Land Surface Uplift and Groundwater Recovery Observed During the Syrian War

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract Recent geopolitical upheaval in Syria is driving regional growth by returning populations, which increases demands on water resources. In northwest Syria, widespread cropland abandonment during the Syrian War starting in 2011 drastically changed the hydrological regime of the region.

Characterization of Near‐Surface Velocity Structure at Haast, New Zealand, Using Distributed Acoustic Sensing (DAS) Measurements of Seismicity

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract Distributed acoustic Sensing (DAS) data collected along a 30 km length of telecommunications fiber crossing the Alpine Fault near Haast enable analysis of interactions between fluvioglacial and seismotectonic processes. Here we use DAS recordings of 25 earthquakes to probe near‐surface structure beneath the Haast river valley.

Holocene Climate Changes: Unraveling Processes, Mechanisms, and Impacts Across Spatiotemporal Scales

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract As the most recent interglacial period and the timeframe for the development of human civilization, the Holocene provides a critical perspective for understanding future climate under continued global warming. This special collection focuses on Holocene climate changes and features 14 interdisciplinary studies.

Fe–Mn Crust δ98Mo Decline Records Tectonic Forcing on Marine Oxide Sink Reduction During the Early Eocene–Early Oligocene

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract S, Tl, and W isotope records document pronounced early Eocene shifts in marine redox, yet the absence of a Mo isotope record obscures its progression. Here, we present ∼80 Myr Mo–Os–Be–Nd isotope profiles from a Northwest Pacific hydrogenetic Fe–Mn crust, revealing a systematic δ98Mo decline from −0.24‰ (early Eocene) to −0.83‰ (early ...

Constraining the Relative Chronology of Repeated Large Earthquakes in the Longmen Shan Thrust Belt, Eastern Tibetan Plateau

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract The Yingxiu–Beichuan Fault Zone (YBFZ), located in the Longmen Shan Thrust Belt (LSTB) on the eastern Tibetan Plateau, is highly seismically active. However, direct evidence of large earthquakes at depth is scarce. Here, we present rock magnetic, microstructural, and geochemical analyses of four fault zones from the Wenchuan Earthquake Fault ...

Depositional and stratigraphic evolution of a Permian megalake system: Implications for seiche‐influenced models

The Depositional Record, Volume 12, Issue 2, April 2026.
During the Late Permian, the rise of the Gondwanides Belt trapped marine waters, giving birth to a vast megalake. This lake shifted between overfilled, balanced‐fill and underfilled stages that are recorded by high‐frequency accommodation changes, while meteorological seiches shaped the sedimentary dynamic and produced heterolithic beds.

Mg isotope fractionation during microbial dolomite formation in the Khor Al‐Adaid sabkha, Qatar

The Depositional Record, Volume 12, Issue 2, April 2026.
Modern sabkha sediments from southern Qatar show ca. 1‰ Ca isotope fractionation between pore water, organic matter and dolomite, supporting microbial mediation. In contrast, minimal Mg isotope fractionation and inorganic‐like dolomite δ26Mg indicate that microbial influence is indirect, expressed through subtle pore water shifts driven by Mg ...
