Ocean surface currents estimated from satellite remote sensing data based on a global hexagonal grid
Global ocean surface currents estimated from satellite derived data based on a regular global grid are affected by the grid’s shape and placement.

Observations of Upwelling and Downwelling Around Antarctica Mediated by Sea Ice
We infer circumpolar maps of stress imparted to the ocean by the wind, mediated by sea-ice, in and around the Seasonal Ice Zone (SIZ) of Antarctica. In the open ocean we compute the wind stress using surface winds from daily atmospheric reanalyses and ...

Real-time Reconstruction of Surface Velocities from Satellite Observations in the Alboran Sea
Surface currents in the Alboran Sea are characterized by a very fast evolution that is not well captured by altimetric maps due to sampling limitations. On the contrary, satellite infrared measurements provide high resolution synoptic images of the ocean

Dual-Polarized Backscatter Features of Surface Currents in the Open Ocean during Typhoon Lan (2017)
Ocean surface current measurements from satellites have historically been limited. We propose a new approach to detect ocean surface currents as observed by dual-polarized (VV and VH) spaceborne synthetic aperture radar (SAR).

Wind work at the air-sea interface: a modeling study in anticipation of future space missions [PDF]
Wind work at the air-sea interface is the transfer of kinetic energy between the ocean and the atmosphere and, as such, is an important part of the ocean-atmosphere coupled system.

GEST Ocean Surface Current product is an estimation of ocean surface current at 15 m depth based on multi-scale physical processes, including geostrophic and Ekman currents, wave-induced tidal currents and Stokes drift. This global daily product covers the period of 2013-2019, with a 0.25° spatial resolution, and is likely to be a good indicator of the

On the Factors Driving Upper-Ocean Salinity Variability at the Western Edge of the Eastern Pacific Fresh Pool [PDF]
The tropical Eastern Pacific Fresh Pool (EPFP) has some of the highest precipitation rates and lowest sea surface salinities found in the open ocean. In addition, the sea surface salinity in the EPFP exhibits one of the strongest annual cycles in the ...

Surface Gravity Wave Interferometry and Ocean Current Monitoring With Ocean‐Bottom DAS
AbstractThe cross‐correlation of a diffuse or random wavefield at two points has been demonstrated to recover an empirical estimate of the Green's function under a wide variety of source conditions. Over the past two decades, the practical development of this principle, termed ambient noise interferometry, has revolutionized the fields of seismology ...

The Particulate Organic Carbon-to-Nitrogen Ratio Varies With Ocean Currents
Ocean currents could adjust ocean carbon and nitrogen composition which are an important part of the global carbon and nitrogen cycle. We procured global concentrations of particulate carbon and nitrogen in different depths, classified them according to ...
