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 ... -
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 ... -
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 ... -
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 ... -
Visible/near-infrared spectral diversity from in situ observations of the Bagnold Dune Field sands in Gale Crater, Mars
(Journal of Geophysical Research: Planets, 2017-12-13)As part of the Bagnold Dune campaign conducted by Mars Science Laboratory rover Curiosity, visible/near-infrared reflectance spectra of dune sands were acquired using Mast Camera (Mastcam) multispectral imaging (445–1013 ... -
Nitrogen and phosphorus loads to temperate seepage lakes associated with allochthonous dissolved organic carbon loads
(American Geophysical Union, 2018-06-16)Terrestrial loads of dissolved organic matter (DOM) have increased in recent years in many north temperate lakes. While much of the focus on the “browning” phenomena has been on its consequences for carbon cycling, much ... -
A model for training undergraduate students in collaborative science
(American Geophysical Union, 2018-08-16)Engagement of undergraduate students in research has been demonstrated to correlate with improved academic performance and retention. Research experience confers many benefits on participants, particularly foundational ... -
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 ... -
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 ... -
The role of wetland coverage within the near-stream zone in predicting of seasonal stream export chemistry from forested headwater catchments
(John Wiley & Sons Ltd., 2019-02-19)Stream chemistry is often used to infer catchment‐scale biogeochemical processes. However, biogeochemical cycling in the near‐stream zone or hydrologically‐connected areas may exert a stronger influence on stream chemistry ... -
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 ... -
Reenvisioning an Energy Strategy for Manitoba: Planning for 2030 and Beyond
(University of Winnipeg, 2020)On March 10, 2020 the Re-envisioning an Energy Strategy for Manitoba: Planning for 2030 and Beyond workshop was held at The University of Winnipeg. The purpose of the event was to initiate a discussion amongst Manitobans ... -
Building the System: Follow-up, monitoring & adaptive management
(University of Winnipeg, 2020-04-08)Does impact assessment (IA) end when the license has been granted? While societal resources tend to focus on rigorous project approvals, what happens to the project, to the public and to the environment once approval is ... -
Access to Environmental Justice: A Manitoba Toolkit for Improving Public Participation; Final Project Report, February 2021
(Manitoba Eco-network, The University of Winnipeg, and Public Interest Law Centre, 2021-02)This final report details the implementation of the Manitoba Law Foundation funded project: Access to Environmental Justice: A Manitoba Toolkit for Improving Public Participation. The project materialized as a 6-part public ... -
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 ... -
Nitrogen dynamics and nitrogen-to-phosphorus stoichiometry in cold region agricultural streams
(Wiley Periodicals LLC on behalf of American Society of Agronomy, Crop Science Society of America, and Soil Science Society of America, 2021-05-12)Cold agricultural regions are getting warmer and experiencing shifts in precipitation patterns, which affect hydrological transport of nutrients through reduced snowpack and higher annual proportions of summer rainfall. ... -
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 ... -
