Submesoscale Ageostrophic Processes in the Kuroshio and Their Impact on Phytoplankton Community Distribution

Journal of Marine Science and Engineering
This study focuses on typical regions of strong ageostrophic processes in the Kuroshio using high-resolution remote sensing satellite reanalysis data and Argo float data. By analyzing the relationship between the Rossby number and chlorophyll concentration from June to August in the summer of 2020, the spatial characteristics of ageostrophic processes ...

Water exchange in the Baltic Sea: a historical view of research approaches from basin scales to submesoscale

Frontiers in Earth Science
At the beginning of the 20th century, Knudsen illustrated that the mean observed salinity of the Baltic Sea could be realistically estimated, assuming an inflow of saline Kattegat water equals the net freshwater supply, also called the Knudsen theorem ...

Submesoscale dynamics in tropical instability waves

, 2011
Submesoscale dynamics in tropical instability waves (TIWs) of the Pacific ocean are analyzed from nested numerical simulations of increasing resolution (36 km, 12 km, and 4 km).

Multi-scale eddy identification and analysis based on deep learning method and ocean color data

International Journal of Digital Earth
Oceanic eddies are ubiquitous phenomena that facilitate the horizontal and vertical transportation of substances under the combination of ocean currents and the Coriolis force, thus they are crucial for the regulation of marine ecosystems.

Submesoscale currents modulate the seasonal cycle of nutrients and productivity in the California Current System

, 2020
In the California Current, subduction by mesoscale eddies removes nutrients from the coastal surface layer, counteracting upwelling and quenching productivity.

Seasonality in submesoscale turbulence [PDF]

, 2014
Although the strongest ocean surface currents occur at horizontal scales of order 100 km, recent numerical simulations suggest that flows smaller than these mesoscale eddies can achieve important vertical transports in the upper ocean. These submesoscale

A numerical study of submesoscale processes in the coastal circulation of Madeira

, 2022
Submesoscale processes are defined geometrically by a lower length scale than the first baroclinic radius of deformation and dynamically by a Rossby number (Ro) of O(1), thus virtually unaffected by planetary forces. They have been widely studied in various environments using in-situ measurements, remote sensing, and numerical modelling.

Submesoscale cyclones in the Agulhas current

, 2017
Gliders 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 100-1000m and over a period of

Ocean forecasting of mesoscale features can deteriorate by increasing model resolution towards the submesoscale

, 2017
Submesoscale dynamics are ubiquitous in the ocean and important in the variability of physical, biological and chemical processes. Submesoscale resolving ocean models have been shown to improve representation of observed variability. We show through data

Uncovering Ocean Mixed Layer Dynamics From the Sea Surface State

Geophysical Research Letters
Submesoscale dynamics strongly influence the upper ocean, regulating mixing, air–sea exchange, and vertical heat transport. The recent Surface Water and Ocean Topography mission provides unprecedented high‐resolution observations of sea surface height ...
