In marine seismic exploration, seismograms recording reflected energy generated from the firing of a seismic source are used to measure the characteristics of the medium through which the energy passes. These measurements are converted into control parameters for an array of seismic sources.

Modal mapping experiments (MOMAX) previously described by Souza, Frisk, and Becker [J. Acoust. Soc. Am. 112, 2281 (2001)] employ a CW-source at a fixed water depth and a receiver also at a fixed depth, with the range between the two varying systematically.

AbstractAnticipating future global freshwater scarcity and providing mitigation require timely knowledge of spatiotemporal dynamics of discharge for gauged and, more challengingly, ungauged rivers. This study describes a coupled hydrologic (SWAT) and hydraulic (XSECT) modeling approach set in a genetic algorithm framework for estimating discharge and ...

Full Waveform Inversion Using Broadband Variable-depth Streamer Data in Deep Water West Africa
Proceedings, 2014Full waveform inversion (FWI) produces high-resolution velocity models through an iterative inversion scheme that minimizes the difference between real and modeled data. Due to the limitations of current FWI algorithms, clean, low-frequency data are desirable to minimize the potential for cycle skipping and crucial for a successful FWI update. We apply

Infrared extinction optical depth (500-5000 cm(-1)) has been measured with a Fourier transform infrared spectrometer for clouds produced with an ultrasonic nebulizer. Direct measurement of the cloud droplet size spectra agree with size spectra retrieved from inversion of the extinction measurements. Both indicate that the range of droplet sizes is 1-14

Fourier hybrid neural bathymetry network for active–passive fusion shallow water depth inversion
Applied OpticsIn this study, a shallow water inversion method based on the Fourier hybrid neural bathymetry network is proposed to address the weak representation of spatial context in active–passive fusion bathymetry. The method uses Ice, Cloud, and land Elevation Satellite-2 laser bathymetry as the reference ground truth and combines Gaofen-2 ...
