Video Sensing of Nearshore Bathymetry Evolution with Error Estimate
Although coastal morphology results essentially from underwater sediment transports, the evolution of underwater beach profiles along the diverse coastlines of the world is still poorly documented.

Uncertainties and shortcomings of ground surface temperature histories derived from inversion of temperature logs [PDF]
Analysing borehole temperature data in terms of ground surface history can add useful information to reconstructions of past climates. Therefore, a rigorous assessment of uncertainties and error sources is a necessary prerequisite for the meaningful ...

Underwater Topography Inversion in Liaodong Shoal Based on GRU Deep Learning Model
The Liaodong Shoal in the east of the Bohai Sea has obvious water depth variation. The clear shallow water area and deep turbid area coexist, which is characterized by complex submarine topography.

A simple but efficient non-linear method for 2D inversion of magnetic field data based on Ridge-Regression algorithm [PDF]
In geophysical exploration, inversion is carried out on the observed data to generate a geophysical model, approximating the subsurface geological structure.

Subsonic near-surface P-velocity and low S-velocity observations using propagator inversion [PDF]
Detailed knowledge of near-surface P- and S-wave velocities is important for processing and interpreting multicomponent land seismic data because (1) the entire wavefield passes through and is influenced by the near-surface soil conditions, (2) both ...

Temperature inversion on the surface of externally heated optically thick multigrain dust clouds [PDF]
It was recently discovered that the temperature in the surface layer of externally heated optically thick gray dust clouds increases with the optical depth for some distance from the surface, as opposed to the normal decrease in temperature with distance

Cenozoic evolution of the eastern Black Sea: a test of depth-dependent stretching models [PDF]
Subsidence analysis of the eastern Black Sea basin suggests that the stratigraphy of this deep, extensional basin can be explained by a predominantly pure-shear stretching history.

Depth Limits in Body Wave Inversions [PDF]
Summary The Wiechert-Herglotz integral provides a direct means of calculating a seismic velocity-depth (v-d) curve from a continuous ray parameter-distance (p-Δ) curve. There is a straightforward method by which this approach can be extended to determine a velocity-depth envelope for any set of T - Δ or p - Δ data.

Analytic Inversion of Emission Lines of Arbitrary Optical Depth for the Structure of Supernova Ejecta [PDF]
We derive a method for inverting emission line profiles formed in supernova ejecta. The derivation assumes spherical symmetry and homologous expansion (i.e., $v(r) \propto r$), is analytic, and even takes account of occultation by a pseudo-photosphere ...
