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 ...

Benguela Upwelling Filaments Are a Significant Pathway of New Nutrients to the South Atlantic Subtropical Gyre

Journal of Geophysical Research: Oceans, Volume 131, Issue 8, August 2026.
Abstract In the transition zones between eastern boundary upwelling regions and subtropical gyres, upwelling and offshore moving filaments generated by frontal instabilities play an important role in the gyre‐ward transport of new nutrients and phytoplankton biomass. However, quantification of such transport using field data remains sparse.

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

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).

The ASTE‐BGC Data‐Assimilative Regional Ocean Biogeochemical Model

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 8, August 2026.
Abstract We present a data‐assimilative regional ocean biogeochemical model, ASTE‐BGC, which simulates the physical and biogeochemical state of the North Atlantic Ocean from 2002 to 2017. Model physics are provided by a physical state estimate (ASTE), which assimilates O(109) in situ and satellite‐based observations over the model domain and time ...

Data Driven Reconstruction of Upper Ocean Profiles for Improved State Estimation in the Philippine Sea

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 8, August 2026.
Abstract Despite significant advances in observational systems such as the global Argo array of autonomous profiling floats, the spatiotemporal coverage of subsurface ocean observations remains limited compared to the dense data provided by satellite platforms. This study develops a data‐driven framework to reconstruct synthetic profiles of upper ocean
