      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 

      Cloutis, Edward A; Bell, James F. III (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 

      Baron, A .A. P.; Dyck, L. T.; Amjad, H.; Bragg, J.; Kroft, E.; Newson, J.; Oleson, K.; Casson, N. J.; North, R. L.; Venkiteswaran, J. J.; Whitfield., C. J. (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 

      Horgan, B. H.; Bell, J. F. III; Noe Dobrea, E. Z.; Cloutis, E. A.; Bailey, D. T.; Craig, M. A.; Roach, L. H.; Mustard, J. F. (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 

      Stanley, Emily H.; Casson, Nora J.; Christel, Samuel T.; Crawford, John T.; Loken, Luke C.; Oliver, Samantha K. (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 

      Kvern, Michael; Fitzpatrick, Patricia; Fishback, LeeAnn (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 ...
