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 ... -
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 ... -
Diaspores and related hydroxides' Spectral-compositional properties and implications for Mars
(Journal of Geophysical Research, 2000-03-25)Differences in spectral reflectance properties (0.3-26 μm) of a suite of metal hydroxides (gibbsite, böhmite, diaspore, goethite, and manganite) have been found to be a function of both structural and compositional differences ... -
Differences in ebullitive methane release from small, shallow ponds present challenges for scaling
(Elsevier B.V., 2022)Small, shallow waterbodies are potentially important sites of greenhouse gas release to the atmosphere. The role of ebullition may be enhanced here relative to larger and deeper systems, due to their shallow water, but ... -
Distribution of hydrated minerals in the north polar region of Mars
(Journal of Geophysical Research, 2009-01-28)The previous discovery of extensive deposits of hydrated minerals in Olympia Planum in the north polar region of Mars by the Mars Express OMEGA instrument raises important questions about the origin and subsequent ... -
The ecology of methane in streams and rivers: patterns, controls, and global significance
(Ecological Society of America, 2015-12-07)Streams and rivers can substantially modify organic carbon (OC) inputs from terrestrial landscapes, and much of this processing is the result of microbial respiration. While carbon dioxide (CO₂) is the major end‐product ... -
Empowering Churchill: Exploring energy security in northern Manitoba
(Arctic Institute of North America, 2022-06-11)To those living in Churchill, Manitoba, having power means much more than being able to turn on the lights. Using Churchill as a case study, we examine how local context can improve the suitability of energy security ... -
Evolution of Occator Crater on (1) Ceres
(The Astronomical Journal, 2017-02-17)The dwarf planet Ceres (diameter 939 km) is the largest object in the main asteroid belt. Recent investigations suggest that Ceres is a thermally evolved, volatile-rich body with potential geological activity, a body which ... -
Forestry and Kaiñgining in the Philippines: A Selected Bibliography
(1980)An annotated bibliography on forests and forestry in the Philippines. Table of contents: 1. Aforestation - Reforestation; 2. Deforestation; 3. Forest Laws/Agencies; 4. Vegetation Cover of R.P.; 5. Parang - Fallow; 6. ... -
Framing Indigenous Partnerships in Energy and Allied Renewable Resource Sectors. Final Report to the Social Sciences and Humanities Research Council of Canada
(2017)Canada is a top five global energy producer and thus is in a leadership position with respect to how it engages in international markets and, increasingly, energy partnerships. Growing global energy demand and international ... -
Hydrological and catchment controls on event-scale dissolved organic carbon dynamics in boreal headwater streams
(Wiley, 2021-06-23)Hydrological events transport large proportions of annual or seasonal dissolved organic carbon (DOC) loads from catchments to streams. The timing, magnitude and intensity of these events are very sensitive to changes in ... -
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 ... -
Imaging spectroscopy of geological samples and outcrops: Novel insights from microns to meters
(GSA Today, 2015-12-01)Imaging spectroscopy is a powerful, non-destructive mineralogic tool that provides insights into a variety of geological processes. This remote measurement technique has been used for decades from orbital or aerial platforms ... -
Intra-urban analysis of commercial locations: A GIS-based approach
(2013)The urban landscape is an interspersed mixing of residences, shops, theatres, parks, natural areas, and a multitude of other uses. From the early days of the central markets, to the planned downtown, to the heavily planned ... -
Isotopic reconstruction of the weaning process in the archaeological population of Canímar Abajo, Cuba: A Bayesian probabilities mixing models approach
(Public Library of Science, 2017-05-01)The general lack of well-preserved juvenile skeletal remains from Caribbean archaeological sites has, in the past, prevented evaluations of juvenile dietary changes. Canímar Abajo (Cuba), with a large number of well-preserved ... -
Lake Manitoba and its Watershed: Knowledge Gaps & Next Steps
(2016)Lake Manitoba is a large, shallow prairie lake located in central Manitoba. The lake and watershed are subject to numerous environmental pressures including climate change, land use change, and regulation of water levels, ... -
Light-toned salty soils and coexisting Si-rich species discovered by the Mars Exploration Rover Spirit in Columbia Hills
(Journal of Geophysical Research, 2008-12-19)Light-toned soils were exposed, through serendipitous excavations by Spirit Rover wheels, at eight locations in the Columbia Hills. Their occurrences were grouped into four types on the basis of geomorphic settings. At ... -
Linking dominant rainfall-runoff event hydrologic response dynamics with nitrate and chloride load estimates of three boreal Shield catchments
(American Geophysical Union, 2021-08-21)Understanding hydrological dynamics in boreal Shield catchments is critical for projecting changes in stream runoff and chemistry in a region that is sensitive to climate change. Previous work has mostly focused on a limited ... -
Manganese-rich olivines: Identification from spectral reflectance properties
(Journal of Geophysical Research, 1997-11-25)Reflectance spectra of manganese-rich olivines were examined to determine which spectral features allow these minerals to be distinguished from forsteritic-fayalitic olivines. The results indicate that manganese-rich ...
