Broadband seismology and noise under the ocean
Most of our understanding of the Earth's interior has been derived from measurements from global seismic networks, although no network has ever been truly “global” because some 71% of the Earth'sExpand

Infragravity waves in the deep ocean
Energetic pressure fluctuations at periods longer than 30 s are a ubiquitous feature of pressure spectra from instruments sited on the deep seafloor in both the Atlantic and the Pacific oceans. WeExpand

A Complex Pattern of Mantle Flow in the Lau Backarc
Shear-wave splitting analysis of local events recorded on land and on the ocean floor in the Tonga arc and Lau backarc indicate a complex pattern of azimuthal anisotropy that cannot be explained byExpand

Determination of surface‐wave phase velocities across USArray from noise and Aki's spectral formulation
[1] We use expressions for the cross-correlation of stochastic surface waves originally derived by Aki (1957) to develop an algorithm for determining inter-station phase-velocity measurements fromExpand

Identifying and Removing Tilt Noise from Low-Frequency (! 0.1 Hz) Seafloor Vertical Seismic Data
Low-frequency (<0.1 Hz) vertical-component seismic noise can be reduced by 25 dB or more at seafloor seismic stations by subtracting the coherent signals derived from (1) horizontal seismicExpand

A Deep-Sea Differential Pressure Gauge
Abstract A pressure gauge configured to respond to the difference between the ocean pressure and the pressure within a confined volume of compressible oil is found to be especially useful forExpand

Seismic attenuation tomography of the Tonga‐Fiji region using phase pair methods
The anelastic structure of the region surrounding the Tonga slab and Lau back arc spreading center in the southwest Pacific is studied using data from 12 broadband island stations and 30 ocean bottomExpand

Variations in the distribution of magma in the lower crust and at the Moho beneath the East Pacific Rise at 9°–10°N
Abstract Measurements of the seafloor deformation under ocean waves (compliance) reveal an asymmetric lower crustal partial melt zone (shear velocity less than 1.8 km/s) beneath the East Pacific RiseExpand

Controlled-source electromagnetic sounding of the oceanic lithosphere
The attenuation of ionospheric signals in the frequency range 0.06–24 Hz by sea water effectively precludes using the magnetotel-luric method to study the electrical structure of the upper oceanicExpand

Depth Extent of the Lau Back-Arc Spreading Center and Its Relation to Subduction Processes
Seismic tomography and wave form inversion revealed that very slow velocity anomalies (5 to 7 percent) beneath the active Lau spreading center extend to 100-kilometer depth and are connected toExpand
