    • In situ observation of the percolation threshold in multiphase magma analogues 

      Colombier, M.ORCIDiD; Wadsworth, F. B.; Scheu, B.ORCIDiD; Vasseur, J.ORCIDiD; Dobson, K. J.; Cáceres, F.ORCIDiD; Allabar, A.ORCIDiD; Marone, F.; Schlepütz, C. M.; Dingwell, D. B.ORCIDiD (Bulletin of Volcanology, 2020-03-04)
      Magmas vesiculate during ascent, producing complex interconnected pore networks, which can act as outgassing pathways and then deflate or compact to volcanic plugs. Similarly, in-conduit fragmentation events during ...

    • Macroporosity and Grain Density of Rubble Pile Asteroid (162173) Ryugu 

      Grott, MatthiasORCIDiD; Biele, JensORCIDiD; Michel, PatrickORCIDiD; Sugita, SeijiORCIDiD; Schröder, StefanORCIDiD; Sakatani, Naoya; Neumann, WladimirORCIDiD; Kameda, ShingoORCIDiD; Michikami, TatsuhiroORCIDiD; Honda, Chikatoshi (Journal of Geophysical Research: Planets, 2020-12-04)
      Rubble pile asteroids such as (162173) Ryugu have large bulk porosities, which are believed to result from void spaces in between the constituent boulders (macroporosity) as well as void spaces within the boulders themselves ...

    • Permeability estimation from induced polarization: an evaluation of geophysical length scales using an effective hydraulic radius concept 

      Weller, AndreasORCIDiD; Slater, Lee (Near Surface Geophysics, 2019)
      Geophysical length scales defined from induced-polarization measurements can be used in models of permeability (k) prediction. We explore the relative merit of different induced-polarization parameters as proxies of an ...
