Ocean Wind and Current Retrievals Based on Satellite SAR Measurements in Conjunction with Buoy and HF Radar Data

open access: yesRemote Sensing, 2017
A total of 168 fully polarimetric synthetic-aperture radar (SAR) images are selected together with the buoy measurements of ocean surface wind fields and high-frequency radar measurements of ocean surface currents.

Ocean surface currents estimated from satellite remote sensing data based on a global hexagonal grid

open access: yesInternational Journal of Digital Earth, 2023
Global ocean surface currents estimated from satellite derived data based on a regular global grid are affected by the grid’s shape and placement.

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

Dual-Polarized Backscatter Features of Surface Currents in the Open Ocean during Typhoon Lan (2017)

open access: yesRemote Sensing, 2018
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).

A Low-Cost, Open-Source, Multi-Purpose Autonomous Surface Vehicle

open access: yesJournal of Marine Science and Engineering
Autonomous surface vehicles (ASVs) have played a crucial role in various areas, including oceanographic research, environmental monitoring, and asset inspection. However, the high cost and proprietary nature of many platforms limit accessibility.

Real-time Reconstruction of Surface Velocities from Satellite Observations in the Alboran Sea

open access: yesRemote Sensing, 2020
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

Observations of Upwelling and Downwelling Around Antarctica Mediated by Sea Ice

open access: yesFrontiers 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 ...

A hybrid breakwater–wave energy converter based on a passive oscillating hydrofoil: numerical assessment of wave attenuation and energy capture

open access: yesResults in Engineering
Floating breakwaters are widely used for coastal protection, yet their ability to harness incident wave energy remains limited. To address this limitation, the present study proposes a novel hybrid floating breakwater integrated with a passive ...

Characterizing the Effect of Ocean Surface Currents on Advanced Scatterometer (ASCAT) Winds Using Open Ocean Moored Buoy Data

open access: yesRemote Sensing, 2023
The ocean surface current influences the roughness of the sea surface, subsequently affecting the scatterometer’s measurement of wind speed. In this study, the effect of surface currents on ASCAT-retrieved winds is investigated based on in-situ ...
