  • Olsen, K. S.; Cloutis, E.; Strong, K. (Geophysical Research Letters, 2012-10-11)
    Intense interest in the characteristics of a methane source on Mars has been spurred by recent observations of a plume structure. The current NASA Mars Science Laboratory and future landers and orbiters will be tasked with ...
  • Enanga, E.M.; Creed, I.F.; Fairweather, T.; Casson, N.J. (American Geophysical Union, 2016-08-25)
    The magnitude of net soil nitrous oxide (N₂O) production from a snow‐covered catchment in a northern temperate forest was investigated. There was considerable net soil N₂O‐N production and consumption through the snowpack, ...
  • Cloutis, Edward A.; Asher, Pranoti M.; Mertzman, Stanley A. (Journal of Geophysical Research, 2002-09-25)
    The 0.3- to 26-μm reflectance spectra of a suite of 28 zeolites were measured and analyzed to derive spectral-compositional-structural relationships. Below ~7 μm, the spectra are largely dominated by absorption features ...
  • Goltz, Douglas M.; Piniuta, Brent; Huebner, Erwin; Attas, Michael; Cloutis, Edward; Broomhead, John (International Journal of Conservation Science, 2013-01-01)
    In this study we describe the application of X-ray fluorescence, variable pressure scanning electron microscopy and visible (420-720 nm) hyperspectral imaging to assess the surface properties of a wood tally stick that was ...
  • Attas, Michael; Cloutis, Edward; Collins, Catherine; Goltz, Douglas; Majzels, Claudine; Mansfield, James R.; Mantsch, Henry H. (The MIT Press, 2003-08-01)
  • Cloutis, Edward A.; Craig, Michael A.; Mustard, John F.; Kruzelecky, Roman V.; Jamroz, Wes R.; Scott, Alan; Bish, David L.; Poulet, François; Bibring, Jean-Pierre; King, Penelope L. (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 ...
  • Attas, Michael; Cloutis, Edward; Collins, Catherine; Goltz, Douglas; Majzels, Claudine; Mansfield, James R.; Mantscha, Henry H. (Leonardo Electronic Archive, 2002-09)
  • 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 ...
  • 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 ...
  • 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 ...
  • 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 ...
  • 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 ...
