Submicroscopic metallic iron in lunar soils estimated from the in situ spectra of the Chang’E-3 mission
(Geophysical Research Letters, 2017-04-22)
Submicroscopic metallic iron (SMFe) created by space weathering has strong effects on the optical properties of the lunar surface. Spectra measured in situ by the visible-near-infrared spectrometer (VNIS) on board the ...
Automated LULC Map Production using Deep Neural Networks
(Taylor & Francis, 2019-01-17)
This article presents an approach to automating the creation of land-use/land-cover classification (LULC) maps from satellite images using deep neural networks that were developed to perform semantic segmentation of natural ...
Summer storms trigger soil N₂O efflux episodes in forested catchments
(American Geophysical Union, 2016-01-14)
Climate change and climate-driven feedbacks on catchment hydrology and biogeochemistry have the potential to alter the aquatic versus atmospheric fate of nitrogen (N) in forests. This study investigated the hypothesis that ...
A Deep Learning Framework: Land-Use/Land-Cover Mapping and Analysis using Multispectral Satellite Imagery
(Springer, 2019-07-17)
In this article, we present an approach to land-use and land-cover (LULC) mapping from multispectral satellite images using deep learning methods. The terms satellite image classification and map production, although used ...
Analysis of Historical Evidence of Climate Change in Western and Northern Canada
(National Museum of Natural Sciences Project on Climatic Change in Canada During the Past 20,000 Years, 1981)
Analysis of historical climatic evidence, now in progress at the Universities of Manitoba and Winnipeg, are based entirely upon Hudson's Bay Company records. The objective is to thoroughly explore the utility of this ...
Stability of hydrated minerals on Mars
(Geophysical Research Letters, 2007-10-20)
The validity of recent identification of various hydrated minerals (kieserite, gypsum, hexahydrite, nontronite, chamosite, and montmorillonite) on Mars was assessed by exposing these minerals to simulated Martian surface ...
Reflectance spectra of "featureless" materials and the surface mineralogies of M- and E-class asteroids
(Journal of Geophysical Research, 1990-01-10)
The 0.3- to 2.6-μm reflectance spectra of meteoritic enstatite (nearly pure MgSiO3), iron meteorite metal, magnetite and amorphous carbon, and various mixtures of these materials with mafic silicates have been measured in ...
Metal-silicate mixtures: Spectral properties and applications to asteroid taxonomy.
(Journal of Geophysical Research, 1990-06-10)
The reflectance spectra of combinations of olivine, orthopyroxene, and iron meteorite metal show systematic variations in spectral properties which can be used to constrain many of the physical and chemical properties of ...
Detection of rotational spectral variation on the M-type asteroid (16) Psyche
(The Astronomical Journal, 2016-12-28)
The asteroid (16) Psyche is of scientific interest because it contains ∼1% of the total mass of the asteroid belt and is thought to be the remnant metallic core of a protoplanet. Radar observations have indicated the ...
Hydrological and seasonal controls of phosphorus in Northern Great Plains agricultural streams
(Alliance of Crop, Soil., and Environmental Science Societies, 2019)
Controls on nutrient transport in cold, low relief agricultural regions vary dramatically among seasons. The spring snowmelt is often the dominant runoff and nutrient loading event of the year. However, climate change may ...
