Seismic Effects of Large Earthquakes on Sea‐Level Budget Closures

Journal of Geophysical Research: Oceans, Volume 131, Issue 7, July 2026.
Abstract Large submarine earthquakes introduce significant distortions into the ocean bottom pressure (OBP) data from the Gravity Recovery and Climate Experiment (GRACE) and its follow‐on mission (GRACE‐FO), leading to non‐closure of regional sea‐level budgets in seismically active oceans.

On the Influence of Currents and Grain Size on Wave Orbital Motion Scaling Dependence of Sand Ripple Geometry

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 7, July 2026.
Abstract Using field observations from the MEGAPEX and Coastal Genesis 2.0 (CG2‐DVT2) campaigns along the Dutch coast, along with laboratory data from the DUNE3 experiment, we examine how ripple geometry responds to variations in orbital diameter, sediment grain size, and current forcing. Results show that ripple wavelength follows a weakly superlinear

Morphological Dating of Fluvial Terrace Risers Across Spatial and Temporal Scales

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 7, July 2026.
Abstract Fluvial terraces are valuable terrestrial records of past climatic and tectonic changes. Morphological dating, which quantifies the degradation of the riser between two terraces, offers a relatively simple and cost‐effective alternative to other dating methods.

Assessing the Relative Roles of Soil Water Potential and Atmospheric Demand on Vegetation Water Stress in Semi‐arid Ecosystems

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 7, July 2026.
Abstract Understanding vegetation's response to soil water availability and atmospheric demand is critical for assessing the impact of drought and climate change on semi‐arid ecosystems. However, limited field‐based research has been conducted to assess the relative importance of these drivers on vegetation productivity.

The Evidence for Linearly Scaling Ocean Gas Exchange With Sea Ice Needs Strengthening

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 7, July 2026.
Abstract Polar oceans are critical components of the oceanic uptake of atmospheric carbon dioxide. Estimates of this uptake across the air‐sea interface require parameterizations of gas transfer velocity that account for variable sea ice concentrations.
