Assessing Drivers of Alongshore Variation in Historical Coastal Dune Evolution: A Field and Model‐Based Approach

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 7, July 2026.
Abstract The protective services provided by coastal foredunes vary spatially due to alongshore differences in dune morphology and hydrodynamic forcing. This study aims to quantify the drivers of alongshore variability of dune evolution across spatial (40‐km) and temporal (multi‐decadal) scales. The alongshore variability in dune evolution is extracted

Tracing the Migration of Fronts in the Pacific Southern Ocean Across the Mid‐Pleistocene Transition

Paleoceanography and Paleoclimatology, Volume 41, Issue 7, July 2026.
Abstract The Southern Ocean is a key driver of global climate variability, yet its dynamics during the Mid‐Pleistocene Transition (MPT; ∼1.25–0.7 Ma) remain poorly understood, especially in the South Pacific sector. The Polar Frontal Zone (PFZ) underwent significant latitudinal shifts during this critical period of climate reorganization.

Integrating Ice Analyses and Varying Floe Size Parameterization Into Great Lakes Ice Prediction

Water Resources Research, Volume 62, Issue 7, July 2026.
Abstract Accurate prediction of Great Lakes ice cover is critical for regional weather, navigation support, and safety. Current operational models often exhibit biases, such as over‐prediction of ice concentration and delayed spring melt, potentially due to simplified parameterizations.

GRDL: A New Global Reservoir Area‐Storage‐Depth Data Set Derived Through Deep Learning‐Based Bathymetry Reconstruction

Water Resources Research
Reservoirs play a critical role in the global water cycle by regulating the flow of water from the environment into human systems. Accurate estimation of the area‐storage‐depth relationships for global reservoirs is essential for effective hydrological ...

Advancing High‐Resolution Lake Bathymetry Reconstruction Through Geomorphologically Informed Deep Learning in High Mountain Asia

Water Resources Research, Volume 62, Issue 7, July 2026.
Abstract Accurate three‐dimensional (3D) lake bathymetry reconstruction is critical for water resources assessment and hydrological modeling yet remains constrained by data scarcity and oversimplified geometric assumptions. To address these challenges, we propose the Geomorphologically informed deep learning (GIDL) framework for high‐resolution 3D lake

Osmium Isotope and Highly Siderophile Element Constraints on the Cretaceous/Paleogene Boundary in Western Pacific Pelagic Clay

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 7, July 2026.
Abstract The Cretaceous/Paleogene (K/Pg) Chicxulub impact produced globally synchronous enrichments of highly siderophile elements (HSEs) and a pronounced decline in marine osmium isotope ratios (187Os/188Os), forming a key geochemical marker of the boundary.

On the Variability of the Agulhas Bank Circulation

Journal of Geophysical Research: Oceans, Volume 131, Issue 7, July 2026.
Abstract This modeling study investigates the variability of the Agulhas Bank (AB) circulation, focusing on its connections to the local wind forcing and the Agulhas Current (AC) as well as to teleconnections to the tropical South Atlantic. The mean AB circulation is dominated by a westward flow composed of a coastal jet, an outer‐shelf flow influenced

Flow‐pattern evolution of the Scandinavian Ice Sheet indicated by the subglacial lineation record over Norway, Sweden and Finland

Boreas, Volume 55, Issue 3, Page 612-669, July 2026.
We present a 25‐stage reconstruction of the ice‐flow pattern evolution of the Scandinavian Ice Sheet based on mapping and analysis of ~240 000 subglacial lineations and lineation fields across Norway, Sweden, Finland, and parts of NW Russia. Our reconstruction uses a glacial geomorphological inversion approach, in which we generated 611 individual ...

Taxonomic and functional diversity of benthic foraminifera as a promising proxy for tidewater glacier retreat

Boreas, Volume 55, Issue 3, Page 885-902, July 2026.
Ice sheets and glaciers globally are losing mass at increasing rates, with the strongest changes occurring at tidewater glaciers. These are rapidly retreating and often transitioning to land‐terminating with implications for sea level change and ecosystem functioning.
