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 ...

Contribution of the SWOT (Surface Water Ocean Topography) satellite for ocean analysis and forecasting

, 2021
La mission SWOT (Surface Water Ocean Topography) qui sera lancée en 2022 doit permettre grâce à un nouveau système d’altimétrie à large fauchée d’observer beaucoup plus finement la topographie des océans (SSH). Cette capacité nouvelle d'observation pose d'importantes questions pour les communautés scientifique et océanographie opérationnelle : quelles ...

SWOT versus legacy satellite missions: assessing water surface elevation and surface water extent in complex river settings

Geocarto International
The Surface Water and Ocean Topography (SWOT) mission represents a significant advancement in satellite altimetry for hydrological applications, yet its performance in complex river systems remains insufficiently characterized.

Ageostrophic Velocities of Curved Ocean Fronts

Journal of Geophysical Research: Oceans, Volume 131, Issue 8, August 2026.
Abstract Ageostrophic velocities at ocean fronts play a key role in ventilating the upper ocean. The overturning circulation driven by cross‐front ageostrophic flow is widely recognized as the major mechanism of vertical transport, but the role of along‐front ageostrophic velocities remains underrepresented in existing theory.

Disentangling Internal Tides From Balanced Motions With Deep Learning and Surface Field Synergy

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 8, August 2026.
Abstract A fundamental challenge in ocean dynamics is disentangling balanced motions and internal waves. Extracting internal tidal (IT) imprints from surface data is a central part of this challenge. Traditional harmonic analysis fails under strong incoherence and poor temporal sampling, as in global satellite observations.

An Adaptive CNN-Based Approach for Improving SWOT-Derived Sea-Level Observations Using Drifter Velocities

Remote Sensing
The Surface Water and Ocean Topography (SWOT) mission provides unprecedented high-resolution observations of sea-surface height. However, their direct use in ocean circulation studies is complicated by the presence of small-scale unbalanced motion ...

A GRACE/‐FO‐Based Framework for Improved Reproduction of Water‐Balance‐Constrained Evapotranspiration Across Hydroclimatic Regimes

Earth and Space Science, Volume 13, Issue 8, August 2026.
Abstract Diagnosing monthly evapotranspiration (ET) under water‐balance constraints is essential for understanding land‐atmosphere interactions and managing water resources under changing climate conditions. Since 2002, the Gravity Recovery and Climate Experiment (GRACE) and its successor GRACE Follow‐On (GRACE/‐FO) missions have provided precise ...

Estimating Baseline Flow Resistance Parameters for Remote Sensing River Discharge (RSQ) From River Morphology Characteristics

JAWRA Journal of the American Water Resources Association, Volume 62, Issue 4, August 2026.
ABSTRACT This study demonstrates that flow resistance in rivers, quantified via calibration of a modified Manning's equation, can inform its estimation from channel hydrometric information available from regional or global datasets for a limited set (N = 14) of rigorously calibrated river reaches in Alaska and with less certainty in a large set (N ...

Characterizing Landslide‐Induced Floods Using the SWOT Mission: A Case Study on the Chilcotin River, Canada

Geophysical Research Letters
Monitoring small rivers during extreme events is challenging, especially in remote areas. This study assesses the accuracy of the Surface Water and Ocean Topography (SWOT) mission in characterizing an extreme hydrological event on a narrow river (∼60 m ...
