  • Steven D. Vance –
    Steven D. Vance Research Focus My research focuses on using geophysical and geochemical methods to understand ocean worlds: how oceans couple to the thermal evolution and composition, and what this might mean for life. I am also interested in the global geochemical fluxes in ocean worlds, by analogy to biogeochemical fluxes in the Earth system. My experimental research involves collecting thermodynamic equations of state for fluids and ices. I have applied these equations of state to evaluating oceanic heat transport and double diffusive convection in Europa, and to the geophysical constraints imposed by ocean composition on the radial structures of Europa, Ganymede, Callisto, Enceladus, and Titan. In recent years I have used these models to explore the parameter space of possible geophysical signals—seismic, magnetic, and gravitational—in the interest of improving the fidelity of returned science from investigations of ocean composition and habitability.

  • I ABSTRACT a CONCEPTUAL MODEL of ICE SHELF
    i ABSTRACT A CONCEPTUAL MODEL OF ICE SHELF SEDIMENTATION Matthew Mayerle, M.S. Department of Geology and Environmental Geosciences Northern Illinois University 2014 Ross Powell, Director Sedimentation studies of polar glacimarine systems remain few relative to temperate glacimarine systems due to the problem of accessibility below ice shelves. This thesis presents a conceptual model of ice shelf sedimentation at the scale of a continental shelf, which is an update of Howat and Domack’s (2003) model. This update adds scale, a third dimension, a decade of research on new geologic/glaciological processes, depositional bias', and greater specificity to their model. The shelf-scale model groups facies into deformation till, glacigenic debris flows, shelfstone mud, and diatomaceous mud. Furthermore, the model is tested and shown to be capable of replicating the facies distribution and major landforms found in two distinctly different Antarctic paleo-ice stream troughs within time constraints dictated by radiometric dating. It is hoped that ideas and techniques presented by this conceptual model will serve as a launching pad for more advanced computational models in the future, which are badly needed in order to help constrain future behavior of ice sheets in a warming world. i NORTHERN ILLINOIS UNIVERSITY DE KALB, ILLINOIS DECEMBER 2014 A CONCEPTUAL MODEL OF ICE SHELF SEDIMENTATION BY MATTHEW WILLIAM MAYERLE ©2014 Matthew Mayerle A THESIS SUBMITTED TO THE GRADUATE SCHOOL IN PARTIAL FULLFILLMENT OF THE REQUIREMENTS FOR THE DEGREE OF MASTER OF SCIENCE DEPARTMENT OF GEOLOGY AND ENVIRONMENTAL GEOSCIENCES Thesis Director: Ross D.

  • Water Density
    Water Density For most normal substances, as heat is removed from the molecules, they are able to get closer together and become denser. And the solid form is the most dense form. However, water behaves much differently as we know well from having our solid ice cubes float atop our liquid sodas. The solid form of water – ice –is LESS dense than the liquid form Why? The shape of the water molecule of course. As long as water molecules have enough velocity, they can slide in and around each other. However, when they slow down enough, they pack together in a hexagonal structure based on hydrogen bonding. This structure leaves a large hole in the middle of every six water molecules and thus produces a more expanded less dense form. Let’s look at that more closely. Once water cools to very near its freezing temperature (zero degrees), it starts to develop zones of crystals in the hexagonal arrangement previously described – the ones that actually take up more space than the liquid form. When does that start to happen? About 4 degrees Celsius. The result? The liquid starts to expand. The water becomes less dense and rises!. And when, at zero degrees Celsius, it completely freezes, it’s now made up of 100% of that expanded crystal structure, and it is so low density that it floats. This behavior is important for natural freshwater bodies on land. It’s what allows fish to survive winter in the bottom of lakes that are frozen. If ice was denser than water, then lakes would freeze from the bottom upwards, and fish would get frozen out of the lakes.
