Interpretation of magnetic anomalies using the horizontal gradient analytic signal
horizontal gradient analytie signal horizontal derivative vertical derivative interpretation aeromagnetic anomaly magnetic anomaly
2015/9/28
In recent years the analytic signal method has been of great utility in the interpretation of potential field data. The amplitude of the 3D analytic signal of magnetic data yields information on the l...
Microgravity vertical gradient measurement in the site of VIRGO interferometric antenna (Pisa plain, Italy)
Microgravity vertical gradient near surface geology gravity modeling
2015/9/1
The site of the European Gravitational Observatory (EGO) located in the countryside near Pisa (Tuscany, Italy) was investigated by a microgravity vertical gradient (MVG) survey. The EGO site houses th...
Multichannel seismic imaging of ocean water column features is a new interdisciplinary study that may become an accepted oceanographic tool in coming years. We now know that reflectors are associated ...
An experimental study of pyroxene crystallization during rapid cooling in a thermal gradient: application to komatiites
Pyroxene crystallization mattie rocks thermal gradient cooling rapidly komatiite lava flow
2015/1/6
To investigate the crystallization of pyroxene in spinifex-textured komatiites, we undertook a series of experiments in which compositions in the CaO-MgO-Al2O3-SiO2 CMAS system were cooled rapidly in ...
Some remarks about lidar data preprocessing and different implementations of the gradient method for determining the aerosol layers
Lidar Aerosol Wavelet Preprocessing
2015/8/17
The determination of atmospheric aerosol layers from lidar returns is possible through automated algorithms. This product is useful, for example, in monitoring the Boundary Layer Height (BLH) as well ...
Flux-gradient relationship for turbulent dispersion over complex terrain
Flux-gradient relationship turbulent dispersion complex terrain
2009/11/16
The transfer of a passive tracer in inhomogeneous turbulent flow is investigated. Starting from Lumley's constitutive equation, we derived an expression for the ratio between the effective eddy diffus...
Gradient evolution for potential vorticity flows
Gradient evolution potential vorticity flows
2009/11/12
Two-dimensional unsteady incompressible flows in which the potential vorticity (PV) plays a key role are examined in this study, through the development of the evolution equation for the PV gradient. ...
Analytical expressions and distributions of vertical gradient of gravity caused by model bodies symmetry with respect to a vertical axis, and characteristics of these maps
gravity model body vertical gradient
2009/3/4
We can find many symmetrical gravity anomalies such as center point symmetry in the gravity map series (1 : 200,000) published by Geological survey of Japan, AIST. To analyze these gravity anomalies, ...
