Although 90% of Antarctica‟s discharge occurs via its fast-flowing ice streams, our ability to project future ice-sheet response has been limited by poor observational constraints on the ice-bed conditions used in numerical models to determine basal slip. We have helped address this observational deficit by acquiring and analysing a series of seismic reflection profiles to determine basal condi...

One of the most important components of the magmatic plumbing system of Kilauea Volcano is the shallow (2–4 km deep) magma storage reservoir that underlies the volcano’s summit region. Nevertheless, the geometry (shape and size) of Kilauea’s summit reservoir is controversial. Two fundamentally different models for the reservoir’s shape have been proposed based on geophysical observations: a ple...

We present zELDA(redshift Estimator for Line profiles of Distant Lyman-Alpha emitters), an open source code to fit (Lya) line profiles. The main motivation is provide the community with easy use and fast tool analyze Lya uniformly improve understating emitting galaxies. zELDA based on commonly used 'shell-model' pre-computed full Monte Carlo radiative transfer LyaRT. Via interpolation between t...

the analysis of geochemical data in frequency domain, as indicated in this research study, can provide new exploratory informationthat may not be exposed in spatial domain. to identify deep geochemical anomalies, sulfide zone and geochemical noises in dalli cu–au porphyry deposit, a new approach based on coupling fourier transform (ft) and principal component analysis (pca) has beenused. the re...

Characterization of material changes with depth (profiles) in many landfill sites can be problematic for some conventional geophysical methods. Localized anomalies within the landfill can complicate mapping of underlying layers, and layered-model techniques are inappropriate for imaging laterally discontinuous landfills. Recently-developed geophysical hardware and software tools provide the opp...
