Increasing Frequency of Coastal Erosion Indicated by a Hindcast Model of Storm‐Driven Forcing Calibrated With Beach Stratigraphy

Earth's Future, Volume 14, Issue 8, August 2026.
Abstract Beach stratigraphy at North Beach, Sandy Hook, New Jersey is used to calibrate a model of coastal erosion, establish a model‐based erosion threshold, and evaluate how often threshold conditions have been exceeded since 1979 through hindcast analysis.

Bathymetry Prediction With SWOT Gravity Anomaly Using Machine Learning Methods: Paper 1–Model Development

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 8, August 2026.
Abstract Only one quarter of the global ocean floor has been directly surveyed; the remaining three quarters are inferred from satellite altimeter‐derived gravity data using techniques developed in the 1990s. These classical methods correlate gravity anomalies with known depths and extrapolate bathymetry in unsounded regions.

Bathymetry Prediction With SWOT Gravity Anomaly Using Machine Learning Methods: Paper 2—Model Evaluation and Uncertainty Analysis

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 8, August 2026.
Abstract Despite millions of ship soundings, bathymetry from satellite derived gravity is still necessary to fill in approximately three quarters of the global oceans. The methods used to carry out this inference have not changed significantly since the 1990s; however new methodology involving Machine Learning (ML) improves the bathymetric predictions ...

Coastal Marine Carbon and Air‐Sea Fluxes Quantified From pH Sensors on an Extended AUV Deployment

Journal of Geophysical Research: Oceans, Volume 131, Issue 8, August 2026.
Abstract For the first time, the Autosub Long Range (ALR) completed a fully autonomous, long‐distance (2,000 km) scientific mission, delivering new insight into coastal carbonate dynamics and air‐sea CO2 ${\text{CO}}_{2}$ fluxes. Equipped with a suite of oceanographic sensors, including a Lab‐on‐Chip (LOC) pH sensor and a Sea‐Bird SeaFET pH sensor, the

Seasonal Forecasts of pH and Aragonite Saturation for the Bering Sea Shelf

Journal of Geophysical Research: Oceans, Volume 131, Issue 8, August 2026.
Abstract The number of numerical model forecasts of ocean environmental conditions has greatly expanded in recent years, including biogeochemical variables. Forecasts can provide marine resource managers with advance warning of extreme events such as heatwaves and hypoxia, though forecast products are scarcer in high‐latitude environments.

A new approach to satellite-derived bathymetry: the use of NDWI and ANN with bathymetry sections for reservoir mapping

Boletim de Ciências Geodésicas
Abstract: Mapping the submerged bottom is a hampered task when traditional vessels are inserted in shallow places that pose a danger to navigation. In this sense, current research has sought optical remote sensing to obtain bathymetry estimates in larger locations in less time.

Preconditioning of Polynya Formation by Ocean Mixing at Maud Rise, Antarctica

Journal of Geophysical Research: Oceans, Volume 131, Issue 8, August 2026.
Abstract Antarctic open‐ocean polynyas trigger vigorous wintertime convection, influencing ocean circulation and atmospheric processes. In the Weddell Sea, interaction between the Weddell Gyre and the Maud Rise seamount generates a Taylor column that favors polynya formation.

Lethal by Design? Resolving Differences Between Experimental and Real‐World Alkalinity Perturbations in Ocean Alkalinity Enhancement

Journal of Geophysical Research: Oceans, Volume 131, Issue 8, August 2026.
Abstract Ocean alkalinity enhancement (OAE) aims to mitigate climate change by increasing the chemical capacity of seawater to store anthropogenic CO2. OAE can be implemented through multiple pathways, each of which intentionally modifies marine carbonate chemistry through increases in total alkalinity (TA).

Estimating Submesoscale‐Driven Particulate Organic Carbon Flux From Remote Sensing at a Dynamic Upwelling Front

Journal of Geophysical Research: Oceans, Volume 131, Issue 8, August 2026.
Abstract Submesoscale (1–10 km) vertical velocities at fronts enhance the exchange of particulate organic carbon (POC) and heat between the surface ocean and depth. While POC and temperature can be readily assessed in situ, direct quantification of flux remains uncertain due to the observational challenges of measuring submesoscale vertical velocities ...

Submarine Flank Collapses at Tagoro Volcano: Insights From Bathymetric Surveys and 3D Multiphase Simulations

Journal of Geophysical Research: Oceans, Volume 131, Issue 8, August 2026.
Abstract Volcanic islands are prone to flank instabilities that can generate tsunamis even when mobilized volumes are moderate. This study investigates submarine collapses during the 2011–2012 eruption south of El Hierro, which built the Tagoro submarine volcano.
