In the eastern Gulf of Guinea (GG), freshwater originated from rivers discharges into the
ocean and high precipitation rate are key contributors to the upper ocean vertical density …

Representing and forecasting global ocean velocities is challenging. Velocity observations
are scarce and sparse, and are rarely assimilated in a global ocean configuration. Recently …

Accurate prediction of ocean surface currents is important for marine safety, ship routing,
tracking of pollutants and in coupled forecasting. Presently, velocity observations are not …

Many human activities rely on accurate knowledge of the sea surface dynamics. This is
especially true during storm events, when wave‐current interactions might represent a …

Ocean surface currents have a profound influence on human life through their role in
horizontal transport and dispersal of pollutants and physical, biological, and chemical …

Estimating the effects of wind and waves (EWW) on the Doppler centroid frequency shift is a
key step in the Synthetic Aperture Radar (SAR) retrieval of ocean currents. However …

The Doppler shift of microwave radar signal is determined by the relative motion between
radar and ocean surface, including contributions from the movement of the radar platform …

The Doppler shift of microwave radar sea surface echoes serves as the foundation for sea
surface current field retrieval; it includes the shift caused by satellite platform motion, ocean …

The Poseidon-4 radar altimeter on board Sentinel-6 “Michael Freilich”(S6-MF) offers unique
opportunities to assess the impact of ocean surface motion on Delay-Doppler altimetry. In …

This paper presents a novel algorithm for estimating the horizontal flow field using inter-
platform measurements of displacement among Lagrangian float systems. The primary …
