Research Projects

  • Characterizing Surface Environments on Mars Through Mineral Identification
    • Relating mineralogy and chemistry on Mars to understanding aqueous geochemistry and climate (Murchie et al., 2009a; 2019; Bishop, 2018; Bishop & Rampe, 2016; Bishop et al. 2016a, 2018a,b).
    • Characterization of phyllosilicate-rich outcrops at Mawrth Vallis (Bishop et al., 2008a; Mckeown et al., 2009a; Noe Dobrea et al., 2010; Bishop et al., 2013a; Bishop & Rampe, 2016; Wray et al., 2010; Loizeau et al., 2015), Libya Montes (Bishop et al., 2013b; Tirsch et al., 2018), and elsewhere (Mustard et al., 2008; Ehlmann et al., 2009; Wray et al., 2011; Weitz et al., 2014).
    • Analysis of sulfate-bearing regions near Valles Marineris and associated chasma (Bishop et al., 2009; Murchie et al., 2009b; Roach et al., 2009, 2010a,b; Weitz et al., 2010), Noctis Labyrinthus (Weitz et al., 2011, 2013; Thollot et al., 2012; Weitz & Bishop, 2016, 2018), Sinus Meridiani Planum (Wiseman et al., 2010) and Aram Chaos (Lichtenberg et al., 2010).
    • Investigation of carbonate-bearing sites (Ehlmann et al., 2008; Brown et al., 2010; Bishop et al., 2013c; Wray et al., 2016).
    • Advancing data-mining techniques (Parente and Bishop, 2008; Parente and Bishop, 2010), developing noise-reduction algorithms (Parente, 2008), creating simulated images for testing of algorithms and Gaussian modeling of CRISM data (Parente et al., 2009b; Parente et al., 2010).
    • Determination of mineral abundances through modeling of CRISM data (Poulet et al., 2014).
    • Identification of likely sulfate and phosphate minerals present in the bright salty outcrops of Gusev crater (Lane et al., 2008; Parente et al., 2009a). Related studies have involved analysis of Pathfinder multichannel images (Bishop et al., 1998; Bishop and Smith, 1999; Bell et al., 2000; Farrand et al., 2008).
    • Several studies integrate data from multiple instrument or multiple missions in order to gain insights about the surface of Mars. These include coordinated CRISM-HiRISE investigations of South Isidis (Bishop et al., 2013b), and chasma near Valles Marineris (Milliken et al., 2008; Bishop et al., 2009; Weitz et al., 2010a,b). Other projects involve integrating VNIR reflectance spectra with emission spectra and Mössbauer spectra (Lane et al., 2004; Bishop et al., 2005).
  • Spectroscopic Properties of Minerals
    • A variety of phyllosilicates and amorphous phases are under study. These include summaries of the spectral properties of many types of clays (Bishop et al., 2008b, 2017a), and additional investigations of smectites (Bishop et al., 1994, 1995, 1999, 2002a,b, 2011), kaolinites and serpentines (Bishop et al., 2002b), and the nanophase materials allophane and imogolite (Bishop et al., 2013d). Analysis of additional phyllosilicates and a large variety of opal, silica glass, imogolite and allophane samples are under way (e.g. Jeute et al., 2018).
    • Characterization of fine-grained hydrated minerals such as ferrihydrite (Bishop et al., 1993; Bishop and Murad, 2002), akaganéite (Murad and Bishop, 2000; Bishop et al., 2014) and schwertmannite (Bishop and Murad, 1996; Bishop et al., 2014). Alteration experiments on several ferrihydrites showed that low-temperature heating produces hematite when no organics are present and maghemite or magnetite when organics are present (Bishop et al., 2000; Bishop et al., 2004a).
    • Numerous studies on sulfates including Ca-sulfates (Bishop et al., 2014) and Fe-bearing sulfates (Lane et al., 2015). Ongoing projects involve characterization of anhydrous, monohydrated and polyhydrated sulfates (Bishop et al., 2005; Dyar et al., 2005; Lane et al., 2005; Bishop et al., 2008c; Lane et al., 2008; Bishop et al., 2009). Efforts are focused on minerals that could be present on Mars.
    • Spectral properties of carbonates and nitrates (Bishop et al., 2017b).
    • Spectral studies of selected phosphates have been initiated (Lane et al., 2007) and continued analyses of phosphate spectra are in progress.
    • Analysis of other aqueous minerals includes carbonate (Bishop et al., 2010a, 2017), perchlorates, nitrates and other N-bearing species (Bishop et al., 2002b). Other mafic minerals under investigation include olivine (Dyar et al., 2009; Lane et al., 2009; Isaacson et al., 2014)) and pyroxene.
    • Spectral properties of olivine (Dyar et al., 2009; Lane et al., 2011; Isaacson et al., 2014).
    • In addition to analysis of spectral features acquired under ambient or mildly dehydrating conditions to remove adsorbed water, some investigations involve low temperature and pressure studies (Bishop and Pieters, 1995; Bishop et al., 1995) and low-temperature heating of sulfates such as copiapite that appear to create a new phase formed on Mars (Bishop et al., 2008e; Milliken et al., 2008; Bishop et al., 2009; Lichtenberg et al., 2010).
    • NH4-treated clays and other materials (Bishop et al., 2002c; Berg et al., 2016) are important for understanding how these species are incorporated into planetary surface materials and identifying them on bodies such as Ceres.
  • Laboratory Mixture Experiments
    • Phyllosilicates and mafic components (Roush et al., 2015).
    • Nontronite, olivine and magnesite (Bishop et al., 2013e).
    • Gypsum with mafics (Clark et al., 2008), dolomite and quartz (King et al., 2013; Lafuente et al., 2014).
    • Cl-salts in mafic matrices (Bishop et al., 2016b).
    • Mixtures of phyllosilicates and sulfates with mafic components in order to understand formation of rock coatings on Mars and to identify chemical and physical mixtures in the martian regolith (Bishop et al., 2002d).
  • Investigation of Mars Analog Field Sites
    • Alteration of volcanic material in the Hawaiian islands (Bishop et al., 1998, 2007, 2016c; Schiffman et al., 2002, 2006) and Iceland (Bishop et al., 2002e; Bishop and Murad, 2002).
    • Precipitates from hot springs at Yellowstone National Park (Bishop et al., 2004b).
    • Soils from the Painted Desert National Park, AZ (McKeown et al., 2009b; Noe Dobrea et al., 2009; Perrin et al., 2018).
    • Sediments from the McMurdo Dry Valleys, Antarctica (Bishop et al., 1996, 2001, 2003, 2013f).
    • Gypsum-rich dunes at White Sands National Monument, NM (King et al., 2013; Lafuente et al., 2014; Fenton et al., 2017).
  • Investigation of Meteorites
    • Martian meteorites (Bishop et al., 1998c,d, 2002; Pieters et al., 2008).
    • Ureillites (Jenniskens et al., 2009; Cloutis et al., 2010; Hiroi et al., 2010).
