Framework to Extract Extreme Phytoplankton Bloom Events with Remote Sensing Datasets: A Case Study

Remote Sensing, 2022
The chlorophyll-a concentration (CHL) is an essential climate variable. Extremes of CHL events directly reflect the condition of marine ecosystems. Here, we applied the statistical framework for defining marine heatwaves to study the extremes of winter ...

Submesoscale potential vorticity

, 2021
Ertel’s potential vorticity theorem is essentially a clever combination of two conservation principles. The result is a conserved scalar q that accurately reflects vorticity values that fluid parcels can possess and acts as a tracer for fluid flow. While true at large horizontal scales in the ocean and atmosphere, at increasingly smaller scales and in ...

Global Patterns of Submesoscale Surface Salinity Variability [PDF]

, 2019
Surface salinity variability on O(1-10) km lateral scales (the submesoscale) generates density variability and thus has implications for submesoscale dynamics.

Submesoscale cyclones in the Agulhas current [PDF]

Geophysical Research Letters, 2017
AbstractGliders were deployed for the first time in the Agulhas Current region to investigate processes of interactions between western boundary currents and shelf waters. Continuous observations from the gliders in water depths of 100–1000 m and over a period of 1 month provide the first high‐resolution observations of the Agulhas Current's inshore ...

Submesoscale Dynamics in the Gulf of Aden and the Gulf of Oman

Fluids, 2020
We have investigated the surface and subsurface submesoscale dynamics in the Gulf of Aden and the Gulf of Oman. Our results are based on the analyses of regional numerical simulations performed with a primitive equation model (HYCOM) at submesoscale ...

Scale dependence of the marine atmospheric boundary‐layer response to ocean surface‐temperature variability in the EUREC4$$ {\mathrm{EUREC}}^4 $$A region

Quarterly Journal of the Royal Meteorological Society, EarlyView.
With a minimal physics model and a high‐resolution fully 3D simulation, we demonstrate that the marine atmospheric boundary layer (MABL) response to sea‐surface temperature (SST) variability displays a dependence on the horizontal scales of motion.

Specialized SWOT SSH Data Assimilation Improves the Representation of Multiscale Variability in the Ocean Model

Geophysical Research Letters, Volume 53, Issue 21, 16 November 2026.
Abstract The Surface Water and Ocean Topography (SWOT) mission provides wide‐swath sea surface height (SSH) observations at scales poorly sampled by conventional altimetry. Assimilating SWOT data remains challenging because part of the short‐wavelength variance may not be dynamically representable by a given model configuration.

Eddy characteristics in the South Indian Ocean as inferred from surface drifters [PDF]

Ocean Science, 2015
Using a geometric eddy identification method, cyclonic and anticyclonic eddies from submesoscale to mesoscale in the South Indian Ocean (SIO) have been statistically investigated based on 2082 surface drifters from 1979 to 2013.

Mixed layer eddies supply nutrients to enhance the spring phytoplankton bloom

Frontiers in Marine Science, 2022
Mixed layer eddies resulting from baroclinic instability of fronts convert horizontal buoyancy gradients into vertical stratification, shoaling the mixed layer.

Evolution of Air‐Sea Fluxes in Modeled Long‐Lived Mesoscale Eddies in the South Atlantic Ocean

Journal of Geophysical Research: Oceans, Volume 131, Issue 11, November 2026.
Abstract Mesoscale eddies modify physical and biogeochemical properties, facilitating the exchange of heat and CO2 between the surface, mixed‐layer and ocean interior. Most state‐of‐the‐art Earth System Models fail to resolve mesoscale processes O $O$(10–100 km) due to computational constraints, thus contributing to uncertainties in current and future ...
