[1] Nonlinear wave‐wave interactions generate double‐ frequency (DF) microseisms, which include both surface waves (mainly Rayleigh‐type) and compressional (P) waves. Although it is unclear whether DF surface waves generated in deep oceans are observed on land, we show that beamforming of land‐based seismic array data allows detection of DF P waves generated by ocean waves from Super Typhoon Io...

In many ocean regions the archipelagoes or even isolated islands provide shelter and this effect has an influence on the wave climate for coasts or ocean areas located in the shadow zones. Incident waves from the deep ocean are blocked by the island boundaries and are refracted over the island shoals. The wave energy is partially dissipated in surf zones or reflected back to the deep ocean. How...

Radar remote sensing of the sea surface for the extraction of ocean surface wave fields requires separating wave and non-wave contributions to the sea surface measurement. Conventional methods of extracting wave information from radar measurements of the sea surface rely on filtering the wavenumber-frequency spectrum using the linear dispersion relationship for ocean surface waves. However, thi...

The primary focus of this research is to integrate dynamical processes of wave and turbulence in the upper ocean surface boundary layer (SBL) into a physics-based computational capability for the timedependent radiative transfer (RT) in the ocean. The combined capability we develop will provide direct forward predictions of the radiance distributions in the upper ocean. We aim to use this capab...

[1] A suite of satellite and in-situ observations are used to study ocean-atmospheric conditions over the tropical Southwest Indian Ocean (SWIO) during 2006–2007 when ElNino and an IndianOcean dipole took place simultaneously. Argo profiles reveal a pronounced up-westward propagation of subsurface warming in the southern tropical Indian Ocean associated with Rossby waves traveling on the slopin...

Many nations have expanded their national energy portfolio to ameliorate the effects of climate change and to ensure the security and certainty of energy availability. These efforts have led to scrutiny of marine renewable energy (MRE) as one of several viable new renewable energy sources. In addition to the need to prove the reliability and efficiency of current and wave energy converters, eff...

Remote sensors operating at electromagnetic wavelengths cannot significantly penetrate ocean water but are effective at observing surface phenomena (such as waves andwinds). Radar remote sensing can also be used to measure ocean currents and the presence of surfactants or slicks. These capabilities are presently being exploited to track the Gulf of Mexico oil spill, for example. For radars tran...

Based on cross-correlations of ambient seismic noise computed using 61 ocean bottom seismometers (OBSs) within the Juan de Fuca (JdF) plate from the Cascadia Initiative experiment and 42 continental stations near the coast of the western United States, we investigate the locations of generation of the primary (11–20 s period) and secondary (5–10 s period) microseisms in the northern Pacific Oce...
