Global Evidence for Off‐Axis Flexural Modification of Abyssal Hill Faults at Mid‐Ocean Ridges

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract Young oceanic lithosphere flexes as axial topography decays across mid‐ocean ridge shoulders, yet this deformation has been quantified at only a few segments, leaving its global expression poorly constrained. We analyzed 50 across‐axis bathymetric profiles from 21 regions spanning slow to fast spreading rates, identified 1,201 abyssal‐hill ...

Impact of an extreme storm event on a multiple intertidal barred coastal system

Earth Surface Processes and Landforms, Volume 51, Issue 8, August 2026.
Extreme storms do not necessarily cause extreme coastal erosion. Integrated DGPS surveys and SWAN nearshore wave modelling reveal that Storm Barra's peak coincided with a low‐tide stage, allowing multiple intertidal bars (MITBs) to dissipate incoming wave energy before it reached Dundrum Bay's shoreline, highlighting the combined role of tidal stage ...

Geomorphology and substrate of Galway Bay, Western Ireland

Journal of Maps, 2020
A combination of multibeam bathymetry and backscatter, LiDAR altimetry and bathymetry, satellite images, and hydrodynamic model outputs were used to map the seafloor and coastline of Galway Bay (western Ireland).

Measuring Centimeter-Scale Sand Ripples Using Multibeam Echosounder Backscatter Data from the Brown Bank Area of the Dutch Continental Shelf

Geosciences, 2020
Backscatter data from multibeam echosounders are commonly used to classify seafloor sediment composition. Previously, it was found that the survey azimuth affects backscatter when small organized seafloor structures, such as sand ripples, are present ...

Probabilistic Hazard Assessment of Coseismic Elastic Surface Deformation for the Leech River Valley–Devil's Mountain Fault System Using Stochastic Source Modeling

Earthquake Spectra, Volume 42, Issue 3, August 2026.
This study investigates the effect of incorporating the Devil's Mountain Fault (DMF) and its interaction with the Leech River Valley Fault (LRVF) on the elastic surface deformation hazard in and near the city of Victoria, British Columbia, Canada. Previously, the surface deformation hazard of the region has been characterized by considering the LRVF ...

Early deglaciation history of the southeastern Baffin Island shelf (Eastern Canadian Arctic Archipelago)

Journal of Quaternary Science, Volume 41, Issue 5, Page 686-701, July 2026.
ABSTRACT During the last glacial period, the Laurentide Ice Sheet (LIS) was the largest terrestrial ice sheet on Earth. Its evolution since the Last Glacial Maximum profoundly influenced Earth's geodynamics and surface processes. Investigating the past dynamics of the LIS provides critical insights into how contemporary ice sheets may respond to ...

Mapping Submarine Sand Wave Bathymetry from Sentinel-2 Texture Using a Spatial-Sequential Deep Learning Model

Remote Sensing
Submarine sand waves are widespread on shallow continental shelves. Their complex morphology and potential mobility create challenges for engineering surveys, navigation safety, and seabed stability assessment.

The Impact of Subglacial Drainage System Evolution and Glacier Lake Outburst on Arctic Fjord Macronutrient Dynamics

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 7, July 2026.
Abstract Global warming is amplified in the Arctic, accelerating glacier melt and freshwater runoff. At tidewater glaciers, runoff typically enters fjords at depth and generates buoyancy‐driven circulation that enhances glacier‐ocean exchanges of energy and matter, influencing macronutrient delivery and marine primary production.
