Biplots for compositional data derived from generalized joint diagonalization…
Biplots constructed from principal components of a compositional data set are an established means to explore its features. Principal Component Analysis (PCA) is also used to transform a set of spatial variables into spatially decorrelated factors. However, because no spatial structures are accounted for in the transformation the application of PCA is limited. In geostatistics and blind source …

Animated visualization of post-glacial land uplift and shore displacement fro…
Post-glacial land uplift and shore displacement are dynamic processes that are challenging to present with cartography and geovisualization. To communicate these phenomena, we have created a dynamic visualization in the form of high-quality animation, utilizing automated processes in the computation and rendering of large raster datasets. We have developed a simplified model to assess the past …

MATLAB functions for extracting hypsometry, stream-length gradient index, ste…
The landscape, developed by the interaction of geological processes, is represented by Digital Elevation Models (DEMs) of various spatial resolutions. These DEMs can be variously analysed for the spatial and linear morphometric indices for landscape characterisation. We have developed MATLAB functions for extracting Hypsometric integral (Hi), Stream Length-gradient (SL) index, Normalized steepn…

Great SCO2T! Rapid tool for carbon sequestration science, engineering, and ec…
CO2 capture and storage (CCS) technology is likely to be widely deployed in the coming decades in response to major climate and economics drivers: CCS is part of every clean energy pathway that limits global warming to 2 °C or less and receives significant CO2 tax credits in the United States. These drivers are likely to stimulate the capture, transport, and storage of hundreds of millions …

Enabling student self-guided field expeditions in geoscience with the GeoXplo…
The pervasiveness of smartphones amongst the undergraduate population has been leveraged to deploy a student-centered learning platform that enables exploration of individual interests and empowers students to become their own fieldtrip guides. We describe an automated learning analytics platform developed by combining a set of readily available web applications with custom scripts to support s…

Comparative analysis of different vegetation indices with respect to atmosphe…
Several remote sensing based indices have been developed for studying vegetation using varied combinations of spectral bands. However, for regions like Gautam Buddha Nagar (GBN) district where the atmospheric condition is highly influenced by particulate matter loading and human-induced pollution, such indices produce faulty results because of the effects of scattering and absorption in the atm…

Relative landscape maturity in the South Rifian Ridges (NW Morocco): Inferenc…
In this paper we present the first landscape maturity analysis of the South Rifian Ridges, part of the southern branch of Gibraltar Arc (Morocco). Since the late Miocene, the southward propagation of anticlines structures is driven by the convergence between the Nubia and Eurasia plates, leading to the closure of the South Rifian Corridor and the ongoing motion of the Rif cordillera. So far lit…

Partial correlations in compositional data analysis
Partial correlations quantify linear association between two variables while adjusting for the influence of the remaining variables. They form the backbone for graphical models and are readily obtained from the inverse of the covariance matrix. For compositional data, the covariance structure is specified from log ratios of variables, which implies changes in the definition and interpretation o…

This research uses an urban soil geochemistry database of elemental concentration to examine the potential relationship between Standardised Incidence Rates (SIRs) of Chronic Kidney Disease (CKD) of uncertain aetiology (CKDu), and cumulative low level geogenic and diffuse anthropogenic contamination of soils with PTEs. A compositional data analysis approach was applied to determine the elementa…

The European Organisation for the Exploitation of Meteorological Satellites (EUMETSAT) disseminates weather and climate-related satellite data to its users via satellite broadcast. As part of this, the EUMETSAT Advanced Retransmission Service (EARS) provides Sensor Data Records (SDR) from the United States satellites Suomi National Polar-orbiting Partnership (S-NPP) and NOAA-20. Due to bandwidt…
