Mapping Hydrothermally Altered Minerals and Gossans using Hyperspectral data …
Identification and delineation of alteration minerals and regolith play an important role in the discrimination of metallic and non-metallic minerals and are also significant for metallic and non-metallic mineralization zone identification. In this work, altered minerals and gossans have been identified in and around the Askot area in eastern Kumaon Himalaya using hyperspectral data. Analysis o…

Geomorphic mapping and investigation of the uplifted piedmont zone between Ha…
Active tectonics plays a crucial role in the landscape evolution at the decadal to thousand to million-year time scale. Datasets to examine landscape changes at a decadal scale are rare in the Indo-Gangetic Plain (IGP), which is one of the most dynamic areas in the Himalayan orogenic front. In this paper, we report decadal-scale landscape changes, which occurred in the last 40 years in the pied…

FracRough—Computer program to calculate fracture roughness from reservoir r…
Measuring roughness of fractures in buried rock is challenging, but important in estimating fracture shear strength and permeability. Here, we present FracRough, a first-of-its-kind computer program that was developed to calculate the joint roughness coefficient (JRC) of reservoir rock fractures from core exterior. Core is often acquired from oil and gas wells using particular drilling bits tha…

Development of a monitoring system for ionospheric TEC variability before the…
Total Electron Content (TEC) in the ionosphere changes before an earthquake and is one of the important parameters in the study of earthquake precursors. Monitoring of TEC in real-time may prove an excellent input for the effective precursory study of earthquakes. In the present study, a Monitoring system was developed to integrate TEC, geomagnetic storm, and solar flare data and to carry out a…

Visualization of evolutionary relationships through geologic time in Timescal…
Evolutionary trees showing interpretations of the divergences, lineages, extinctions and relative abundances of life forms through geologic time provide a very useful visualization for both public audiences and research communities. The Java-based TimeScale Creator platform was originally designed to present graphics of Earth history with a streamlined interface. We have added an evolutionary t…

Unsupervised clustering of LA-ICP-MS raster map data for geological interpret…
Raster element concentration maps created using laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) can be used to interpret microscale compositional and textural domains within mineral grains. Raster maps are typically evaluated element by element; however, application of statistical techniques (such as cluster analysis) can enhance the generation of geochemical domains to …

Robust input layer for neural networks for hyperspectral classification of da…
Hyperspectral classification using artificial neural networks is commonly applied on camera dependent interpolated data, or on the results of a dimensionality reduction algorithm. While these methods usually produce satisfactory results, they have severe limitations when part of the spectrum is missing, for example when parts of the image are overexposed or affected by bad pixels.

PS-InSAR derived deformation study in the Kachchh, Western India
The accumulation of crustal strain towards the western part of India, especially in the Kachchh Rift basin, is making one of the most seismically active parts of the Indian plate. Several strong to major earthquakes, including the recent 2001 (M7.7) Bhuj earthquake, were triggered in the Kachchh rift basin during the last two centuries. Therefore, in the present study, we have attempted to quan…

Monitoring and mapping of snow cover variability using topographically derive…
The Himalayas is an essential component of the cryosphere due to the large extent of snow or ice cover. The mapping and monitoring of snow cover variability over the Himalayas is the focus of many scientific studies due to the major source of water for Asian countries and equally important for climate change studies. This study describes the analysis of snow cover variability over North Indian …

Modeling the spatial pattern of sediment flow in lower Hugli estuary, West Be…
Suspended sediment concentration (SSC) information on the coastal waters is necessary for understanding and management of the estuarine environment. It serves as an indicator of coastal erosion and deposition. It is challenging for a macro-tidal estuary like the Hugli with a complex hydrodynamic condition and depth variations to estimate suspended sediment concentration by field observations on…
