The Effects of Late Pleistocene Sea‐Level Fluctuations and Sediment Transport Processes on the Sequestration of Fresh and Brackish Water in Continental Shelf Environments

Water Resources Research, Volume 62, Issue 8, August 2026.
Abstract Offshore fresh groundwater (OFG) is regarded as a significant, albeit typically non‐renewable, unconventional water resource stored within continental shelves. Many models of offshore freshwater emplacement use present‐day stratigraphy while applying Pleistocene sea‐level fluctuations.

Learning 2D Shallow Water Equations With Physics‐Informed Neural Operator Networks

Water Resources Research, Volume 62, Issue 8, August 2026.
Abstract This study investigates the application of Physics‐Informed Neural Operators (PINOs) for solving the two‐dimensional shallow water equations (2D SWE) in the context of flood modeling. Unlike Physics‐Informed Neural Networks (PINNs), which require retraining for each new initial or boundary condition (BC), PINOs learn the solution operator ...

A Subgrid Correction Scheme for Accurate km‐Scale Coastal Inundation in the Energy Exascale Earth System Model

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 8, August 2026.
Abstract Global Earth system models describe many large‐scale processes, such as sea level changes, that affect the evolution of risk in local‐scale coastal flooding due to extreme events such as hurricane storm surges. However, these models operate at resolutions that are too coarse to resolve coastal ocean tidal and storm surge exchanges across the ...

Assessing the Conservation Status, Drivers of Threat and Available Occurrence Records of Sub‐Saharan African Freshwater Molluscs: Gaps and Patterns

African Journal of Ecology, Volume 64, Issue 6, August 2026.
ABSTRACT Freshwater molluscs are key bioindicators of ecosystem health, yet their conservation status and data coverage in sub‐Saharan Africa remain poorly understood. Mollusca is the third most evaluated phylum on the IUCN Red List in Africa, with 1394 species assessed (656 freshwater), of which 39.6% are Least Concern and 12% Critically Endangered ...

Fault Migration and Basin Evolution During Complex Rifting: Examples From the Western North Gulf of Evia, Greece

Basin Research, Volume 38, Issue 4, July–August 2026.
The Western Basin of the North Gulf of Evia rift is a complex, normal fault‐controlled basin. In this study we develop the first pre‐Holocene syn‐kinematic age model here and apply it to better understand rift evolution, basin control, and timing of fault migration in the active rift.

Early‐Life Disaster Exposure and the Investment Response to Monetary Policy

Financial Review, Volume 61, Issue 3, Page 701-723, August 2026.
ABSTRACT We place CEOs' formative experiences at the center of analyzing how firms respond to monetary policy. Specifically, we examine how early‐life exposure to natural disasters shapes CEOs’ investment behavior following monetary shocks. CEOs with exposure to moderate natural disasters during their formative years exhibit stronger risk‐taking ...

The Ames impact structure, Oklahoma: New radioisotopic constraints and implications for North American impact chronology

Meteoritics &Planetary Science, Volume 61, Issue 8, Page 2103-2139, August 2026.
Abstract The Ames impact structure (Oklahoma) is thought to have formed during the Ordovician Meteor Event, based on conodont biostratigraphy of its crater fill. Here, U–Pb zircon dates from its impact‐melt portion, conducted using secondary ion mass spectrometry and laser ablation–inductively coupled plasma–mass spectrometry (n = 37 spots), yield a ...

Formation process of the gravel‐dominated deposit from the 2011 Tohoku‐oki tsunami in Ofunato, northeastern Japan, inferred by integrating sedimentology and tsunami modelling

Sedimentology, Volume 73, Issue 5, Page 1378-1402, August 2026.
ABSTRACT Tsunami deposits serve as geological records of past events and are essential for understanding the occurrence and dynamics of tsunamis. However, conventional research has largely focused on sandy and boulder deposits, leaving gravel‐dominated tsunami deposits comparatively underexplored; furthermore, their characteristics and formation ...

Physics-informed neural networks for tsunami inundation modeling

Journal of Computational Physics
We use physics-informed neural networks for solving the shallow-water equations for tsunami modeling. Physics-informed neural networks are an optimization based approach for solving differential equations that is completely meshless. This substantially simplifies the modeling of the inundation process of tsunamis. While physics-informed neural networks
