Effects of Wind, Waves, and Currents on Icebergs and Surface Floats in the Labrador Sea: A Modeling Study

open access: yesJournal of Marine Science and Engineering, 2022
This article presents a model study of the dynamics of icebergs and surface floats in the Labrador Sea. The model was forced with data on the wind above the ocean surface, surface waves, and ocean currents. These data were obtained from the reanalysis of

A Variational Stereo Method for the Three-Dimensional Reconstruction of Ocean Waves [PDF]

open access: yes, 2011
We develop a novel remote sensing technique for the observation of waves on the ocean surface. Our method infers the 3-D waveform and radiance of oceanic sea states via a variational stereo imagery formulation.

Velocity Estimation of Ocean Surface Currents in along-Track InSAR System Based on Conditional Generative Adversarial Networks

open access: yesRemote Sensing, 2021
Velocity estimation of ocean surface currents is of great significance in the fields of the fishery, shipping, sewage discharge, and military affairs. Over the last decade, along-track interferometric synthetic aperture radar (along-track InSAR) has been

The physical oceanography of the transport of floating marine debris [PDF]

open access: yes, 2020
Marine plastic debris floating on the ocean surface is a major environmental problem. However, its distribution in the ocean is poorly mapped, and most of the plastic waste estimated to have entered the ocean from land is unaccounted for.

On Sub-ENSO Variability [PDF]

open access: yes, 2006
Multichannel singular spectrum analysis (MSSA) of surface zonal wind, sea surface temperature (SST), 20° isotherm depth, and surface zonal current observations (between 1990 and 2004) identifies three coupled ocean–atmosphere modes of variability in the ...

Integrated Observations of Global Surface Winds, Currents, and Waves: Requirements and Challenges for the Next Decade

open access: yesFrontiers in Marine Science, 2019
Ocean surface winds, currents, and waves play a crucial role in exchanges of momentum, energy, heat, freshwater, gases, and other tracers between the ocean, atmosphere, and ice.

Seasonal variations of sea-surface salinity and temperature in the tropical Indian Ocean [PDF]

open access: yes, 1996
Measurements of sea-surface temperature and sea-surface salinity obtained from ships-of-opportunity are used to map the fields in the tropical Indian Ocean.

Derivation and Evaluation of Satellite-Based Surface Current

open access: yesFrontiers in Marine Science, 2021
Observations of real-time ocean surface currents allow one to search and rescue at ocean disaster sites and investigate the surface transport and fate of ocean contaminants.

Surface-circulation change in the southwest Pacific Ocean across the Middle Eocene Climatic Optimum: inferences from dinoflagellate cysts and biomarker paleothermometry [PDF]

open access: yesClimate of the Past, 2020
Global climate cooled from the early Eocene hothouse (∼52–50 Ma) to the latest Eocene (∼34 Ma). At the same time, the tectonic evolution of the Southern Ocean was characterized by the opening and deepening of circum-Antarctic gateways ...
