On the global estimates of geostrophic and Ekman surface currents [PDF]
Limnology and Oceanography: Fluids and Environments, 2013 Lay AbstractA fundamental goal of physical oceanography is to provide a primary description of global ocean circulation. Historically, ocean surface currents were inferred from ship drift measurements, mainly in relation with navigational requirements. Ocean circulation was shown to play an important role in the last decades for studying the transport ...

Geophysical Research Letters, 2018 Although various numerical experiments have been carried out to investigate the cascade of internal tide energy associated with parametric subharmonic instability (PSI), most of them assume idealized oceanic situations, ignoring the existence of ...

Wind-induced variability in the Northern Current (northwestern Mediterranean Sea) as depicted by a multi-platform observing system [PDF]
Ocean Science, 2018 The variability and evolution of the Northern Current (NC) in the area off Toulon is studied for 2 weeks in December 2011 using data from a glider, a high-frequency (HF) radar network, vessel surveys, a weather station, and an atmospheric model.

Geostrophic Transport in the Benguela Current Region [PDF]
Journal of Physical Oceanography, 1989 Historical data from the region between the Greenwich meridian and the African continental shelf are used to compute the offshore geostrophic transport of the Benguela Current. At 32°S, the Benguela Current is located near the African coast, transporting about 21 Sv (1 Sv = 106 m3 s−1) of surface water toward the north relative to a potential density ...

Trends in Atlantic equatorial current variability [PDF]
, 1987 Approximately twice-monthly expendable bathythermograph (XBT) sections between Europe and Brazil, are used to characterize trends in the equatorial geostrophic surface currents orthogonal to the sections between September, 1980 and May, 1984.

Observations of Upwelling and Downwelling Around Antarctica Mediated by Sea Ice
Frontiers in Marine Science, 2022 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 ...

Sea surface height anomaly and geostrophic current velocity from altimetry measurements over the Arctic Ocean (2011–2020) [PDF]
Earth System Science Data, 2023 Satellite altimetry missions flying over the ice-covered Arctic Ocean have opened the possibility of further understanding changes in the ocean beneath the sea ice.

Bottom-trapped currents as statistical equilibrium states above topographic anomalies [PDF]
, 2012 Oceanic geostrophic turbulence is mostly forced at the surface, yet strong bottom-trapped flows are commonly observed along topographic anomalies. Here we consider the case of a freely evolving, initially surface-intensified velocity field above a ...

A novel filtering method for geodetically determined ocean surface currents using deep learning
Environmental Data Science, 2023 Determining an accurate picture of ocean currents is an important societal challenge for oceanographers, aiding our understanding of the vital role currents play in regulating Earth’s climate, and in the dispersal of marine species and pollutants ...

World ocean annual mean absolute geostrophic velocity on marine geoid of EIGEN‐6C4 from WOA13
Geoscience Data Journal, 2022 This data set was established from two open sources: (a) geoid undulation (N) from EIGEN‐6C4, which is a static global combined gravity field model up to degree and order 2,190, and (b) ‘World ocean geostrophic velocity inverted from World Ocean Atlas ...
