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 ...
Physical characterization of ~2 m diameter near-Earth asteroid 2015 TC25: A possible boulder from E-type asteroid (44) Nysa
(The Astronomical Journal, 2016-11-11)
Small near-Earth asteroids (NEAs) (<20 m) are interesting, because they are progenitors for meteorites in our terrestrial collection. The physical characteristics of these small NEAs are crucial to our understanding of 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 ...
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 ...
Oxo Crater on (1) Ceres: Geological History and the Role of Water-ice
(The Astronomical Journal, 2017-08-04)
Dwarf planet Ceres (∅ ∼ 940 km) is the largest object in the main asteroid belt. Investigations suggest that Ceres is a thermally evolved, volatile-rich body with potential geological activity, a body that was never ...
A model for the development of types of atolls and volcanic islands on the Pacific lithospheric plate
(The Smithsonian Institution, Washington, D.C., 1983-09)
A literature review on atoll origins and volcanic island development on the Pacific lithospheric plate is combined with bathymetric data on the Hawaiian, Marshall, Caroline, Tuamotu and Society island chains to produce a ...
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 ...
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 ...
Composition of Jupiter irregular satellites sheds light on their origin
(EDP Sciences, 2017)
Context. Irregular satellites of Jupiter with their highly eccentric, inclined and distant orbits suggest that their capture took place after the giant planet migration.
Aims. We aim to improve our understanding of the ...
More than Talking Heads?!? How do administrative tribunals hear from the public? A report prepared for the Consumers’ Association of Canada – Manitoba Branch
(2021-04-30)
Consumers and the general public want a say in the decisions which affect them. However, access to meaningful engagement in regulatory decisions is uneven across jurisdictions, as well as across types of tribunals. Scholarship ...
