Relationship between Large-Scale Variability of North Pacific Waves and El Niño-Southern Oscillation

open access: yesJournal of Marine Science and Engineering, 2023
Ocean waves are crucial for driving various oceanic processes. In this study, the spatial and temporal distribution of significant wave height (SWH) in the North Pacific (NP) is analyzed using the 42-year ERA5 reanalysis dataset from European Centre for ...

Effect of Geosynthetics on Swell Reduction During an Extreme Rainfall Event

open access: yes, 2023
Expansive (reactive) soils can swell during rainfall causing damage to engineering structures. This paper seeks to investigate the effect of geosynthetic material on the swell reduction of such soils.

Experimental Evidence of Swell Signatures in Airborne L5/E5a GNSS-Reflectometry

open access: yesRemote Sensing, 2020
As compared to GPS L1C/A signals, L5/E5a Global Navigation Satellite System-Reflectometry (GNSS-R) improves the spatial resolution due to the narrower auto-correlation function. Furthermore, the larger transmitted power (+3 dB), and correlation gain (+10

On the parameterization of the drag coefficient in mixed seas

open access: yesScientia Marina, 2012
An analysis of the performance of parameterizations for the drag coefficient CD over the ocean is presented. The results were obtained by considering detailed observations from the recent IntOA experiment in which a co-existence of wind sea and swell ...

Effect of Nonlinear Elasticity on the Swelling Behaviors of Highly Swollen Polyelectrolyte Gels

open access: yesGels, 2021
Polyelectrolyte gels exhibit swelling behaviors that are dependent on the external environment. The swelling behaviors of highly charged polyelectrolyte gels can be well explained using the Flory–Rehner model combined with the Gibbs–Donnan effect and ...

Swell

open access: yes, 2015
Swell is a visual deconstruction of the vital data many surfers use to plan the weekend activities. Based around wave direction and wind patterns, this set of hand pulled and vinyl posters explores the graphical journey in which we follow.
