Green’s functions for geophysics: a review

The Green's function (GF) method, which makes use of GFs, is an important and elegant tool for solving a given boundary-value problem for the differential equation from a real engineering or physical field. Under a concentrated source, the ...

Geophysics Under Stress

This is a recording of the 2010 Distinguished Instructor Short Course (DISC) by Colin Sayers. The state of stress within the earth has a profound effect on the propagation of seismic and borehole acoustic waves, this leads to many important...

Fractals in Geology and Geophysics

The definition of a fractal distribution is that the number of objects N with a characteristic size greater than r scales with the relation N ~ r −D . The frequency-size distributions for islands, earthquakes, fragments, ore deposits, and o...

Integrated geochemical evaluation of hydrocarbon source potential in late quaternary sediments of the Nkhata basin, Malawi

Abstract The Nkhata basin located in the central part of the Malawi rift consists of Late Quaternary (Chibanian to present;  6.02 wt% and S2 > 25.55 mg HC/g rock; 1 C: TOC up to 6.16 wt%, S2 up to 56.9 mg HC/g rock). The sediments were domi...

Anomalous effect in Schumann resonance phenomena observed in Japan, possibly associated with the Chi-chi earthquake in Taiwan

The Schumann resonance phenomenon has been monitored at Nakatsugawa (near Nagoya) in Japan since the beginning of 1999, and due to the occurance of a severe earthquake (so-called Chi-chi earthquake) on 21 September 1999 in Taiwan we have...

Comparison of the GOSAT TANSO-FTS TIR CH volume mixing ratio vertical profiles with those measured by ACE-FTS, ESA MIPAS, IMK-IAA MIPAS, and 16 NDACC stations

The primary instrument on the Greenhouse gases Observing SATellite (GOSAT) is the Thermal And Near infrared Sensor for carbon Observations (TANSO) Fourier transform spectrometer (FTS). TANSO-FTS uses three short-wave infrared (SWIR) band...

Pb, Sr, and Nd isotopic characteristics of a variety of lithologies from the Guerrero composite terrane, west-central Mexico: constraints on their origin

Análisis isotópicos de Pb, Sr y Nd de rocas mesozoicas y cenozoicas de la parte sur del terreno Guerrero en México contribuyen una mejor comprensión de su origen. Rocas metamórficas colectadas al sur de Arteaga (terreno Zihuatanejo) tienen ...

Multitask Learning Mechanism for Remote Sensing Image Motion Deblurring

As a fundamental preprocessing technique, remote sensing image motion deblurring is important for visual understanding tasks. Most conventional approaches formulate the image motion deblurring task as a kernel estimation. Because the kernel...

Automated Burris gravity meter for single and continuous observation

The Burris Gravity Meter™ manufactured by ZLS Corporation, Austin/Texas, USA, is based on the invention of L&R (L. LaCoste and A. Romberg): The ZLS (zero-length spring). A digital feedback system (range of about 50 mGal) is used to null the...

Turbulence properties and kinetic signatures of electrons in Kelvin-Helmholtz waves during a geomagnetic storm

The Kelvin–Helmholtz instability (KHI), in its nonlinear phase, plays a significant role in transporting solar-wind plasma into Earth’s magnetosphere. This study investigates the turbulence properties and reconnection signatures observed at...

Terrestrial Remote Sensing of Snowmelt in a Diverse High-Arctic Tundra Environment Using Time-Lapse Imagery

Snow cover is one of the crucial factors influencing the plant distribution in harsh Arctic regions. In tundra environments, wind redistribution of snow leads to a very heterogeneous spatial distribution which influences growth conditions f...

Assessment of climate change impact on wheat crop using MarkSim GCM in Varanasi, Uttar Pradesh

GFLD-CM3 model was used to generate weather data under RCPs scenario i.e. RCP 2.6, 4.5, 6.0 and 8.5 for years 2010, 2035, 2065 and 2095 for Varanasi, Uttar Pradesh. The generated data were used to assess the impact of climate change on phen...
