Martian Crater Morphology
ANALYSIS OF THE DEPTH-DIAMETER RELATIONSHIP OF MARTIAN CRATERS A Capstone Experience Thesis Presented by Jared Howenstine Completion Date: May 2006 Approved By: Professor M. Darby Dyar, Astronomy Professor Christopher Condit, Geology Professor Judith Young, Astronomy Abstract Title: Analysis of the Depth-Diameter Relationship of Martian Craters Author: Jared Howenstine, Astronomy Approved By: Judith Young, Astronomy Approved By: M. Darby Dyar, Astronomy Approved By: Christopher Condit, Geology CE Type: Departmental Honors Project Using a gridded version of maritan topography with the computer program Gridview, this project studied the depth-diameter relationship of martian impact craters. The work encompasses 361 profiles of impacts with diameters larger than 15 kilometers and is a continuation of work that was started at the Lunar and Planetary Institute in Houston, Texas under the guidance of Dr. Walter S. Keifer. Using the most ‘pristine,’ or deepest craters in the data a depth-diameter relationship was determined: d = 0.610D 0.327 , where d is the depth of the crater and D is the diameter of the crater, both in kilometers. This relationship can then be used to estimate the theoretical depth of any impact radius, and therefore can be used to estimate the pristine shape of the crater. With a depth-diameter ratio for a particular crater, the measured depth can then be compared to this theoretical value and an estimate of the amount of material within the crater, or fill, can then be calculated. The data includes 140 named impact craters, 3 basins, and 218 other impacts. The named data encompasses all named impact structures of greater than 100 kilometers in diameter. -

Mars, interior; Impact processes Abstract We derive synthetic electrical conductivity, seismic velocity, and density distributions from the results of martian mantle convection models affected by basin-forming meteorite impacts. The electrical conductivity features an intermediate minimum in the strongly depleted topmost mantle, sandwiched between higher conductivities in the lower crust and a smooth increase toward almost constant high values at depths greater than 400 km. The bulk sound speed increases mostly smoothly throughout the mantle, with only one marked change at the appearance of β-olivine near 1100 km depth. -
Appendix I Lunar and Martian Nomenclature
APPENDIX I LUNAR AND MARTIAN NOMENCLATURE LUNAR AND MARTIAN NOMENCLATURE A large number of names of craters and other features on the Moon and Mars, were accepted by the IAU General Assemblies X (Moscow, 1958), XI (Berkeley, 1961), XII (Hamburg, 1964), XIV (Brighton, 1970), and XV (Sydney, 1973). The names were suggested by the appropriate IAU Commissions (16 and 17). In particular the Lunar names accepted at the XIVth and XVth General Assemblies were recommended by the 'Working Group on Lunar Nomenclature' under the Chairmanship of Dr D. H. Menzel. The Martian names were suggested by the 'Working Group on Martian Nomenclature' under the Chairmanship of Dr G. de Vaucouleurs. At the XVth General Assembly a new 'Working Group on Planetary System Nomenclature' was formed (Chairman: Dr P. M. Millman) comprising various Task Groups, one for each particular subject. For further references see: [AU Trans. X, 259-263, 1960; XIB, 236-238, 1962; Xlffi, 203-204, 1966; xnffi, 99-105, 1968; XIVB, 63, 129, 139, 1971; Space Sci. Rev. 12, 136-186, 1971. Because at the recent General Assemblies some small changes, or corrections, were made, the complete list of Lunar and Martian Topographic Features is published here.

Park2 and Dah-Ning Yuan2 Submitted to: Science 12 October 2012 Spacecraft-to-spacecraft tracking observations from the Gravity Recovery and Interior Laboratory (GRAIL) have been used to construct a gravitational field of the Moon to spherical harmonic degree and order 420. The GRAIL field reveals features not previously resolved, including tectonic structures, volcanic landforms, basin rings, crater central peaks, and numerous simple craters. From degrees 80 through 300, over 98% of the gravitational signature is associated with topography, which reflects the preservation of craters in highly fractured crust. The remaining 2% represents fine details of subsurface structure not previously resolved. Ghost craters in the maria are not abundant, consistent with underlying highland crust being significantly modified by dikes and intrusions. GRAIL elucidates the role of impact bombardment in homogenizing the distribution of shallow density anomalies on terrestrial planetary bodies. _____________ The Moon is a key to deciphering the evolutionary history of the terrestrial planets because it is the most accessible planetary body that preserves a surface record spanning most of solar system history. Reconstructing planetary evolution requires an understanding of the structure of the interior, which contains information on bulk composition, differentiation, and the nature of heat generation and heat loss that has influenced the style, extent, and duration of volcanism and tectonics. -

ORIGIN of the VALLEY NETWORKS on MARS: a HYDROLOGICAL PERSPECTIVE Virginia C. Gulick* Space Science Division, MS 245-3 NASA-Ames
ORIGIN OF THE VALLEY NETWORKS ON MARS: A HYDROLOGICAL PERSPECTIVE Virginia C. Gulick* Space Science Division, MS 245-3 NASA-Ames Research Center Moffett Field, CA 94035 (415) 604-0781 vgulick @ mail.arc.nasa, gov Manuscript accepted for publication in the special Planetary issue of Geomorphology *also at Dept. of Astronomy, New Mexico State University, Las Cruces, NM 2" Abstract The geomorphology of the Martian valley networks is examined from a hydrological perspective for their compatibility with an origin by rainfall, globally higher heat flow, and localized hydrothermal systems. Comparison of morphology and spatial distribution of valleys on geologic surfaces with terrestrial fluvial valleys suggests that most Martian valleys are probably not indicative of a rainfall origin, nor are they indicative of formation by an early global uniformly higher heat flow. In general, valleys are not uniformly distributed within geologic surface units as are terrestrial fluvial valleys. Valleys tend to form either as isolated systems or in clusters on a geologic surface unit leaving large expanses of the unit virtually untouched by erosion. With the exception of fluvial valleys on some volcanoes, most Martian valleys exhibit a sapping morphology and do not appear to have formed along with those that exhibit a runoff morphology. In contrast, terrestrial sapping valleys form from and along with runoff valleys. The isolated or clustered distribution of valleys suggests localized water sources were important in drainage development. Persistent ground-water outflow driven by localized, but vigorous hydrothermal circulation associated with magmatism, volcanism, impacts, or tectonism is, however, consistent with valley morphology and distribution. Snowfall from sublimating ice-covered lakes or seas may have provided an atmospheric water source for the formation of some valleys in regions where the surface is easily eroded and where localized geothermal/hydrothermal activity is sufficient to melt accumulated snowpacks. -

Sustainable Development – an Empirical Study About Failure Or Success at the Local Government Level
EU Support for Cities towards Sustainable Development – An Empirical Study about Failure or Success at the Local Government Level Edward Cameron and Marko Joas1 Åbo Akademi University Abstract The European Union is often viewed as a quasi-federal construct characterised by a voluntary pooling of sovereignty by member national governments. However, the integration of Europe also has serious consequences for sub national governance including significant impacts on local authorities and cities. Over the past two decades in particular the relationship between Europe and local/regional government has undergone profound change. What began as an “ever closer union” between nation states fifty years ago is today showing more and more signs of an evolving system of multi-level governance. There is a growing activism in the relations between the EU and local government. Local and regional authorities are becoming far more insistent and dynamic in the way they demand a voice in the preparation of European plans, programmes and policies. In particular, local authorities stress that the principle of subsidiarity as enshrined in European treaties, gives them legal, moral, and practical credibility as stakeholders in the European policy process. From the EU perspective, it is clear that more and more European initiatives, whether legislative or funding in nature, permeate to the local level. The growing partnership is recognition of a fundamental understanding between the different levels of governance, namely that the European Union needs sub- national bodies to implement policy, and on the other side, that local and regional authorities need European assistance to build the necessary knowledge, human resource, and financial capacity to facilitate improved implementation. -
