Deep Learning‐Based Statistical Downscaling of Sea Surface Temperature Using a Residual Corrective Neural Network

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 5, October 2026.
Abstract The large‐scale oceanic and atmospheric forecasts provided by global climate models typically lack sufficient resolution to accurately capture the response of the coastal ocean to atmospheric forcing and coastal circulation that drive fine‐scale sea surface temperature (SST) variability.

The role of submesoscale currents in structuring marine ecosystems [PDF]

Nature Communications, 2018
AbstractFrom microbes to large predators, there is increasing evidence that marine life is shaped by short-lived submesoscales currents that are difficult to observe, model, and explain theoretically. Whether and how these intense three-dimensional currents structure the productivity and diversity of marine ecosystems is a subject of active debate. Our

Evaluating SWOT Satellite Data With Gage Information in the United States and Canada

Water Resources Research, Volume 62, Issue 10, October 2026.
Abstract The Surface Water and Ocean Topography (SWOT) satellite mission represents a transformative approach to water resources management, offering high‐resolution data on water‐surface elevations (WSE) and extents. This study evaluates SWOT WSE accuracy in the United States and Canada with in situ streamgage and lake and reservoir gage data.

Coherent Lagrangian swirls among submesoscale motions [PDF]

Proceedings of the National Academy of Sciences, 2018
Significance The detection of vortices in geophysical flows is important because of their role in global circulation and transport. The recent theory of elliptic Lagrangian coherent structures has shown that long-lived, coherent material eddies exhibiting no filamentation can be extracted from altimetry-derived surface velocities ...

Residence Time of Lagrangian Profiling Floats: Observational Assessment and Numerical Simulation of Station Keeping Ability

Earth and Space Science, Volume 13, Issue 10, October 2026.
Abstract Autonomous profiling floats have revolutionized global ocean observation, yet their passive drift limits their ability to remain within desired regions. Using observations and simulations with numerical ocean models, we quantify observed and potential residence time (RT) of profiling floats and explore station‐keeping strategies.

Drifter Observations Reveal Intense Vertical Velocity in a Surface Ocean Front

Geophysical Research Letters, 2022
Measuring vertical motions represent a challenge as they are typically 3–4 orders of magnitude smaller than the horizontal velocities. Here, we show that surface vertical velocities are intensified at submesoscales and are dominated by high frequency ...

Microbial Respiration Across Subtropical Eddies: Submesoscale Variability and Biogeochemical Drivers

Journal of Geophysical Research: Oceans, Volume 131, Issue 10, October 2026.
Abstract Island‐induced eddies from the Canary Islands region propagate southwestward along the Canary Eddy Corridor, exporting biological and biogeochemical properties to the oligotrophic open ocean. However, their contribution to organic matter remineralization, and consequently to the biological carbon pump, throughout their life cycle remains ...
