Seafloor cabled observatories have an obvious role as part of the sustained infrastructure needed to observe climate variability. To highlight this point a couple of important discoveries of the physical climate of the ocean that have been based on data acquired at open ocean “observatories” are reviewed. Perhaps the more important role for observatories in physical oceanography may be the prov...

Research toward the development of point absorber ocean wave energy converters (WEC) is migrating from energy absorption of ocean wave heave only, to the absorption of heave and surge. Due to the additional dimension of surge, the mathematic relationship between the ocean waves and the WEC has shifted from a linear model to a nonlinear model. This change has made back driven wave height from de...

This work shows results of sound signal amplitude fluctuation measurements in comparably narrow envelope frequency spectrum interval from 1.5 to 6.0 mHz obtained on different stationary tomographic systems 100 km, 100 Hz in Barentz sea and 320 km, 400 Hz in Okhotsk sea. Use of this range, from our point of view, in any ocean region allows to decrease influence of two meeting ocean wave processe...

Wind, wave and current interactions control the boundary fluxes, momentum and energy exchange between the atmosphere and the ocean, and within the water column. The wind wave effect on surface stress is investigated using a three-dimensional time-dependant ocean circulation model. The POM (Princeton Ocean Model) based model is implemented with realistic coastlines in South China Sea and emphasi...

Wave-mean flow equations for mass and momentum conservation in three dimensions, previously obtained with a vertical coordinate transform, are generalized here to random waves, and re-derived from the Generalized Lagrangian Mean equations. Combining the momentum equation with a three-dimensional equation for wave pseudo-momentum yields a set of equations describing the interactions of waves, me...

Wind, wave and current interactions control the boundary fluxes, momentum and energy exchange between the atmosphere and the ocean, and within the water column. The wind wave effect on the circulation is investigated in a threedimensional time-dependant ocean circulation model. This POM (Princeton Ocean Model) based model is implemented with realistic coastlines in South China Sea and emphasize...

[1] Earth’s background vibrations at frequencies below about 0.5 Hz have been attributed to ocean-wave energy coupling into the ground and propagating as surface waves and P-waves (compressional waves deep within the Earth). However, the origin and nature of seismic noise on land at frequencies around 1 Hz has not yet been well studied. Using array beamforming, we analyze the seismic noise fiel...

A two-dimensional numerical model with a space grid of about 14 km is applied to calculate diurnal tidal constituents K1 and O1 in the Arctic Ocean. Calculated corange and cotidal charts show that along the continental slope, local regions of increased sea level amplitude, highly variable phase and enhanced currents occur. It is shown that in these local regions, shelf waves (topographic waves)...

Among numerous sources emitting pressure waves a few are known to generate acoustic signals both in the earth, as seismic waves, and in the atmosphere, as infrasound, which were recorded over large distances. Those sources are near surface phenomena like volcanic eruptions, explosions, and ocean waves, which all occur at the boundary between the solid earth and the atmosphere, either shallow ab...
