    • Submicroscopic metallic iron in lunar soils estimated from the in situ spectra of the Chang’E-3 mission 

      Wang, Zhenchao; Wu, Yunzhao; Blewett, David T.; Cloutis, Edward A.; Zheng, Yongchun; Chen, Jun (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 ...

    • Summer storms trigger soil N₂O efflux episodes in forested catchments 

      Enanga, E.M.; Creed, I.F.; Casson, N.J.; Beall, F.D. (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 ...

    • Surface albedo and spectral variability of Ceres 

      Li (李荐扬), Jian-Yang; Reddy, Vishnu; Nathues, Andreas; Le Corre, Lucille; Izawa, Matthew R. M.; Cloutis, Edward A.; Sykes, Mark V.; Carsenty, Uri; Castillo-Rogez, Julie C.; Hoffmann, Martin; Jaumann, Ralf; Krohn, Katrin; Mottola, Stefano; Prettyman, Thomas H.; Schaefer, Michael; Schenk, Paul; Schröder, Stefan E.; Williams, David A.; Smith, David E.; Zuber, Maria T.; Konopliv, Alexander S.; Park, Ryan S.; Raymond, Carol A.; Russell, Christopher T. (The Astrophysical Journal Letters, 2016-01-29)
      Previous observations suggested that Ceres has active, but possibly sporadic, water outgassing as well as possibly varying spectral characteristics over a timescale of months. We used all available data of Ceres collected ...

    • Temporal observations of bright soil exposures at Gusev crater, Mars 

      Rice, M. S.; Bell, J. F. III; Cloutis, E. A.; Wray, J. J.; Herkenhoff, K. E.; Sullivan, R.; Johnson, J. R.; Anderson, R. B (Journal of Geophysical Research, 2011-01-27)
      The Mars Exploration Rover Spirit has discovered bright soil deposits in its wheel tracks that previously have been confirmed to contain ferric sulfates and/or opaline silica. Repeated Pancam multispectral observations ...

    • Visible/near-infrared spectral diversity from in situ observations of the Bagnold Dune Field sands in Gale Crater, Mars 

      Johnson, Jeffrey R.; Achilles, Cherie; Bell, James F. III; Bender, Steve; Cloutis, Edward; Ehlmann, Bethany; Fraeman, Abigail; Gasnault, Olivier; Hamilton, Victoria E.; Le Mouélic, Stéphane; Maurice, Sylvestre; Pinet, Patrick; Thompson, Lucy; Wellington, Danika; Wiens, Roger C. (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 ...

    • When Jewish settlers farmed in Manitoba 

      Richtik, J. [James]; Hutch, D. [Danny] (Royal Canadian Geographical Society, 1977)
      Traces the history of Bender Hamlet, a planned agricultural village located in the Interlake (the area between lakes Winnipeg and Manitoba), about 80 km from Winnipeg. The settlement was organized by a land speculator, ...
